Since Wrangler handles authentication, you do not need to pass API tokens in your commands. The following commands are available: | Command | Description | | ----------------------- | ---------------------------- | | wrangler browser create | Create a new browser session | | wrangler browser close | Close a session | | wrangler browser list | List active sessions | | wrangler browser view | View a live browser session | The `create` command spins up a browser instance on Cloudflare's network and returns a session URL. Once created, you can connect to the session using any [CDP](https://edgetunnel-b2h.pages.dev/browser-run/cdp/)\-compatible client like [Puppeteer](https://edgetunnel-b2h.pages.dev/browser-run/cdp/puppeteer/), [Playwright](https://edgetunnel-b2h.pages.dev/browser-run/cdp/playwright/), or [MCP clients](https://edgetunnel-b2h.pages.dev/browser-run/cdp/mcp-clients/) to automate browsing, scrape content, or debug remotely. ```sh wrangler browser create ``` Use `--keepAlive` to set the session keep-alive duration (60-600 seconds): ```sh wrangler browser create --keepAlive 300 ``` The `view` command auto-selects when only one session exists, or prompts for selection when multiple sessions are available. All commands support `--json` for structured output, and because these are CLI commands, you can incorporate them into scripts to automate session management. For full usage details, refer to the [Wrangler commands documentation](https://edgetunnel-b2h.pages.dev/browser-run/reference/wrangler-commands/). Apr 14, 2026 1. ### [Introducing Cloudflare Mesh](https://edgetunnel-b2h.pages.dev/changelog/post/2026-04-14-cloudflare-mesh/) [ Cloudflare One ](https://edgetunnel-b2h.pages.dev/cloudflare-one/) [Cloudflare Mesh](https://edgetunnel-b2h.pages.dev/cloudflare-one/networks/connectors/cloudflare-mesh/) is now available ([blog post ↗](https://blog.cloudflare.com/mesh/)). Mesh connects your services and devices with post-quantum encrypted networking, allowing you to route traffic privately between servers, laptops, and phones over TCP, UDP, and ICMP. ![Cloudflare Mesh network map showing nodes and devices connected through Cloudflare](https://edgetunnel-b2h.pages.dev/_astro/mesh-network-map.CED6jNHK_ZlOsym.webp) #### What Cloudflare Mesh does * Assigns a private [Mesh IP](https://edgetunnel-b2h.pages.dev/cloudflare-one/networks/connectors/cloudflare-mesh/#mesh-ips) to every enrolled device and node. * Enables any participant to reach any other participant by IP — including client-to-client, without deploying any infrastructure. * Supports [CIDR routes](https://edgetunnel-b2h.pages.dev/cloudflare-one/networks/connectors/cloudflare-mesh/routes/) for subnet routing through Mesh nodes. * Supports [high availability](https://edgetunnel-b2h.pages.dev/cloudflare-one/networks/connectors/cloudflare-mesh/high-availability/) with active-passive replicas for nodes with routes. * All traffic flows through Cloudflare, so [Gateway network policies](https://edgetunnel-b2h.pages.dev/cloudflare-one/traffic-policies/network-policies/), [device posture checks](https://edgetunnel-b2h.pages.dev/cloudflare-one/reusable-components/posture-checks/), and access rules apply to every connection. #### What changed * **WARP Connector** is now **Cloudflare Mesh**. Existing WARP Connectors are now called mesh nodes. All existing deployments continue to work — no migration required. * **Peer-to-peer connectivity** is now called **Mesh connectivity** and is part of the Cloudflare Mesh documentation. * **Mesh node limit** increased from 10 to **50 per account**. * New [dashboard experience ↗](https://dash.cloudflare.com/?to=/:account/mesh) at **Networking** \> **Mesh** with an interactive network map, node management, route configuration, diagnostics, and a setup wizard. #### Get started Refer to the [Cloudflare Mesh documentation](https://edgetunnel-b2h.pages.dev/cloudflare-one/networks/connectors/cloudflare-mesh/) to set up your first Mesh network. Apr 14, 2026 1. ### [Detect Cloudflare API tokens with DLP](https://edgetunnel-b2h.pages.dev/changelog/post/2026-04-14-cloudflare-api-token-detections/) [ Data Loss Prevention ](https://edgetunnel-b2h.pages.dev/cloudflare-one/data-loss-prevention/) The **Credentials and Secrets** DLP profile now includes three new predefined entries for detecting Cloudflare API credentials: | Entry name | Token prefix | Detects | | ---------------------------------- | ------------ | ------------------------- | | Cloudflare User API Key | cfk\_ | User-scoped API keys | | Cloudflare User API Token | cfut\_ | User-scoped API tokens | | Cloudflare Account Owned API Token | cfat\_ | Account-scoped API tokens | These detections target the new [Cloudflare API credential format](https://edgetunnel-b2h.pages.dev/fundamentals/api/get-started/token-formats/), which uses a structured prefix and a CRC32 checksum suffix. The identifiable prefix makes it possible to detect leaked credentials with high confidence and low false positive rates — no surrounding context such as `Authorization: Bearer` headers is required. Credentials generated before this format change will not be matched by these entries. #### How to enable Cloudflare API token detections 1. In the [Cloudflare dashboard ↗](https://dash.cloudflare.com/), go to **Zero Trust** \> **DLP** \> **DLP Profiles**. 2. Select the **Credentials and Secrets** profile. 3. Turn on one or more of the new Cloudflare API token entries. 4. Use the profile in a Gateway HTTP policy to log or block traffic containing these credentials. Example policy: | Selector | Operator | Value | Action | | ----------- | -------- | ------------------------- | ------ | | DLP Profile | in | _Credentials and Secrets_ | Block | You can also enable individual entries to scope detection to specific credential types — for example, enabling **Account Owned API Token** detection without enabling **User API Key** detection. For more information, refer to [predefined DLP profiles](https://edgetunnel-b2h.pages.dev/cloudflare-one/data-loss-prevention/dlp-profiles/predefined-profiles/). Apr 14, 2026 1. ### [Configure how sensitive data appears in DLP payload logs](https://edgetunnel-b2h.pages.dev/changelog/post/2026-04-14-configurable-payload-log-masking/) [ Gateway ](https://edgetunnel-b2h.pages.dev/cloudflare-one/traffic-policies/)[ Data Loss Prevention ](https://edgetunnel-b2h.pages.dev/cloudflare-one/data-loss-prevention/) You can now configure how sensitive data matches are displayed in your DLP payload match logs — giving your incident response team the context they need to validate alerts without compromising your security posture. To get started, go to the [Cloudflare dashboard ↗](https://dash.cloudflare.com/), select **Zero Trust** \> **Data loss prevention** \> **DLP settings** and find the **Payload log masking** card. Previously, all DLP payload logs used a single masking mode that obscured matched data entirely and hid the original character count, making it difficult to distinguish true positives from false positives. This update introduces three options: * **Full Mask (default):** Masks the match while preserving character count and visual formatting (for example, `***-**-****` for a Social Security Number). This is an improvement over the previous default, which did not preserve character count. * **Partial Mask:** Reveals 25% of the matched content while masking the remainder (for example, `***-**-6789`). * **Clear Text:** Stores the full, unmasked violation for deep investigation (for example, `123-45-6789`). **Important:** The masking level you select is applied at detection time, before the payload is encrypted. This means the chosen format is what your team will see after decrypting the log with your private key — the existing encryption workflow is unchanged. **Applies to all enabled detections:** When a masking level other than Full Mask is selected, it applies to all sensitive data matches found within a payload window — not just the match that triggered the policy. Any data matched by your enabled DLP detection entries will be masked at the selected level. For more information, refer to [DLP logging options](https://edgetunnel-b2h.pages.dev/cloudflare-one/data-loss-prevention/dlp-policies/logging-options/#log-the-payload-of-matched-rules). Apr 14, 2026 1. ### [Improved OAuth experience for consent and management](https://edgetunnel-b2h.pages.dev/changelog/post/2026-04-14-oauth-consent-and-revoke/) [ Cloudflare Fundamentals ](https://edgetunnel-b2h.pages.dev/fundamentals/) OAuth allows third-party applications to access your Cloudflare account on your behalf — like when Wrangler deploys Workers or when monitoring tools read your analytics. You now have **granular control** over which accounts these applications can access, plus the ability to revoke access anytime. #### What's new #### Choose which accounts to authorize When authorizing an OAuth application, you can now **select specific accounts** instead of granting access to all your accounts: * **Account-by-account selection** — Choose exactly which accounts the application can access * **"All accounts" option** — Still available for trusted tools like Wrangler This gives you precise control who can access your data. #### Clear consent screens The OAuth consent screen now shows: * **What the application can access** — Explicit list of permissions being requested * **Who created the application** — Application owner and contact information * **Which accounts you're authorizing** — Checkboxes for account selection #### Revoke access anytime Manage authorized OAuth applications from your profile: * **See all connected apps** — View every OAuth application with access to your accounts * **Review permissions and scope** — Check what each application can do and which accounts it can access * **Revoke instantly** — Remove access with one click when you no longer need it To manage your OAuth applications, navigate to **Profile** \> **Access Management** \> **[Connected Applications ↗](https://dash.cloudflare.com/profile/access-management/authorization)**. #### Why this matters These updates give you: * **Granular control** — Authorize apps per-account instead of all-or-nothing * **Transparency** — Know exactly what you're authorizing before you consent * **Security** — Limit blast radius by restricting access to only necessary accounts * **Easy cleanup** — Revoke access when applications are no longer needed #### Learn more Read more about these improvements in our blog post: [Improving the OAuth consent experience ↗](https://blog.cloudflare.com/improved-developer-security/#improving-the-oauth-consent-experience). Apr 14, 2026 1. ### [Logpush to BigQuery — Cloudflare dashboard support](https://edgetunnel-b2h.pages.dev/changelog/post/2026-04-14-bigquery-dashboard-support/) [ Logpush ](https://edgetunnel-b2h.pages.dev/logs/logpush/)[ Logs ](https://edgetunnel-b2h.pages.dev/logs/) You can now configure Logpush jobs to Google BigQuery directly from the Cloudflare dashboard, in addition to the existing API-based setup. Previously, setting up a BigQuery Logpush destination required using the Logpush API. Now you can create and manage BigQuery Logpush jobs from the **Logpush** page in the Cloudflare dashboard by selecting **Google BigQuery** as the destination and entering your Google Cloud project ID, dataset ID, table ID, and service account credentials. For more information, refer to [Enable Logpush to Google BigQuery](https://edgetunnel-b2h.pages.dev/logs/logpush/logpush-job/enable-destinations/bigquery/). Apr 14, 2026 1. ### [Generate citations on Cloudflare Radar](https://edgetunnel-b2h.pages.dev/changelog/post/2026-04-14-radar-citations/) [ Radar ](https://edgetunnel-b2h.pages.dev/radar/) [**Radar**](https://edgetunnel-b2h.pages.dev/radar/) shareable widgets now include a **generate citation** action, making it easier to reference [Cloudflare Radar ↗](https://radar.cloudflare.com) data in research papers and other publications. ![Screenshot of the generate citation icon in the widget action bar](https://edgetunnel-b2h.pages.dev/_astro/citation-action-icon.B2QPGPhA_Z1HBoYT.webp) Select the citation icon to open a modal with five supported citation styles: * **BibTeX** * **APA** * **MLA** * **Chicago** * **RIS** ![Screenshot of the citation modal with format options](https://edgetunnel-b2h.pages.dev/_astro/citation-modal.Bf5eDHwO_2t0GWX.webp) Explore the feature on any shareable widget at [Cloudflare Radar ↗](https://radar.cloudflare.com). Apr 14, 2026 1. ### [Email obfuscation decode script is now non-render-blocking](https://edgetunnel-b2h.pages.dev/changelog/post/2026-04-14-email-obfuscation-defer/) [ WAF ](https://edgetunnel-b2h.pages.dev/waf/) The decode script injected by [Email Address Obfuscation](https://edgetunnel-b2h.pages.dev/waf/tools/scrape-shield/email-address-obfuscation/) now loads with the `defer` attribute. This means the script no longer blocks page rendering. It downloads in parallel with HTML parsing and executes after the document is fully parsed, before the `DOMContentLoaded` event. This improves page loading performance, contributing to better Core Web Vitals, for all zones with Email Address Obfuscation on. No action is required. If you have custom JavaScript that depends on email addresses being decoded at a specific point during page load, note that the decode script now executes after HTML parsing completes rather than inline during parsing. Apr 14, 2026 1. ### [VPC Networks and Cloudflare Mesh support now in public beta](https://edgetunnel-b2h.pages.dev/changelog/post/2026-04-14-vpc-networks/) [ Workers VPC ](https://edgetunnel-b2h.pages.dev/workers-vpc/) [VPC Network](https://edgetunnel-b2h.pages.dev/workers-vpc/configuration/vpc-networks/) bindings now give your Workers access to any service in your private network without pre-registering individual hosts or ports. This complements existing [VPC Service](https://edgetunnel-b2h.pages.dev/workers-vpc/configuration/vpc-services/) bindings, which scope each binding to a specific host and port. You can bind to a [Cloudflare Tunnel](https://edgetunnel-b2h.pages.dev/cloudflare-one/networks/connectors/cloudflare-tunnel/) by `tunnel_id` to reach any service on the network where that tunnel is running, or bind to your [Cloudflare Mesh](https://edgetunnel-b2h.pages.dev/cloudflare-one/networks/connectors/cloudflare-mesh/) network using `cf1:network` to reach any Mesh node, client device, or subnet route in your account: * [ wrangler.jsonc ](#tab-panel-5027) * [ wrangler.toml ](#tab-panel-5028) **JSONC** ```jsonc { "vpc_networks": [ { "binding": "MESH", "network_id": "cf1:network", "remote": true } ] } ``` **TOML** ```toml [[vpc_networks]] binding = "MESH" network_id = "cf1:network" remote = true ``` At runtime, `fetch()` routes through the network to reach the service at the IP and port you specify: **JavaScript** ```js const response = await env.MESH.fetch("http://10.0.1.50:8080/api/data"); ``` For configuration options and examples, refer to [VPC Networks](https://edgetunnel-b2h.pages.dev/workers-vpc/configuration/vpc-networks/) and [Connect Workers to Cloudflare Mesh](https://edgetunnel-b2h.pages.dev/workers-vpc/examples/connect-to-cloudflare-mesh/). Apr 13, 2026 1. ### [Containers and Sandboxes are now generally available](https://edgetunnel-b2h.pages.dev/changelog/post/2026-04-13-containers-sandbox-ga/) [ Containers ](https://edgetunnel-b2h.pages.dev/containers/) Cloudflare [Containers](https://edgetunnel-b2h.pages.dev/containers/) and [Sandboxes](https://edgetunnel-b2h.pages.dev/sandbox/) are now generally available. Containers let you run more workloads on the Workers platform, including resource-intensive applications, different languages, and CLI tools that need full Linux environments. Since the initial launch of Containers, there have been significant improvements to Containers' performance, stability, and feature set. Some highlights include: * [Higher limits](https://edgetunnel-b2h.pages.dev/changelog/post/2026-02-25-higher-container-resource-limits/) allow you to run thousands of containers concurrently. * [Active-CPU pricing](https://edgetunnel-b2h.pages.dev/changelog/post/2025-11-21-new-cpu-pricing/) means that you only pay for used CPU cycles. * [Easy connections to Workers and other bindings](https://edgetunnel-b2h.pages.dev/changelog/post/2026-03-26-outbound-workers/) via hostnames help you extend your Containers with additional functionality. * [Docker Hub support](https://edgetunnel-b2h.pages.dev/changelog/post/2026-03-24-docker-hub-images/) makes it easy to use your existing images and registries. * [SSH support](https://edgetunnel-b2h.pages.dev/changelog/post/2026-03-12-ssh-support/) helps you access and debug issues in live containers. The [Sandbox SDK](https://edgetunnel-b2h.pages.dev/sandbox/) provides isolated environments for running untrusted code securely, with a simple TypeScript API for executing commands, managing files, and exposing services. This makes it easier to secure and manage your agents at scale. Some additions since launch include: * [Live preview URLs](https://edgetunnel-b2h.pages.dev/changelog/post/2025-08-05-sandbox-sdk-major-update/) so agents can run long-lived services and verify in-flight changes. * [Persistent code interpreters](https://edgetunnel-b2h.pages.dev/changelog/post/2025-08-05-sandbox-sdk-major-update/) for Python, JavaScript, and TypeScript, with rich structured outputs. * [Interactive PTY terminals](https://edgetunnel-b2h.pages.dev/changelog/post/2026-02-09-pty-terminal-support/) for real browser-based terminal access with multiple isolated shells per sandbox. * [Backup and restore APIs](https://edgetunnel-b2h.pages.dev/changelog/post/2026-02-23-sandbox-backup-restore-api/) to snapshot a workspace and quickly restore an agent's coding session without repeating expensive setup steps. * [Real-time filesystem watching](https://edgetunnel-b2h.pages.dev/changelog/post/2026-03-03-sandbox-watch-file-events/) so apps and agents can react immediately to file changes inside a sandbox. For more information, refer to [Containers](https://edgetunnel-b2h.pages.dev/containers/) and [Sandbox SDK](https://edgetunnel-b2h.pages.dev/sandbox/) documentation. Apr 13, 2026 1. ### [Secure credential injection and dynamic egress policies for Sandboxes](https://edgetunnel-b2h.pages.dev/changelog/post/2026-04-13-sandbox-outbound-workers-tls-auth/) [ Containers ](https://edgetunnel-b2h.pages.dev/containers/)[ Agents ](https://edgetunnel-b2h.pages.dev/agents/) Outbound Workers for [Sandboxes](https://edgetunnel-b2h.pages.dev/sandbox/) and [Containers](https://edgetunnel-b2h.pages.dev/containers/) now support zero-trust credential injection, TLS interception, allow/deny lists, and dynamic per-instance egress policies. These features give platforms running agentic workloads full control over what leaves the sandbox, without exposing secrets to untrusted workloads, like user-generated code or coding agents. #### Credential injection Because outbound handlers run in the Workers runtime, outside the sandbox, they can hold secrets the sandbox never sees. A sandboxed workload can make a plain request, and credentials are transparently attached before a request is forwarded upstream. For instance, you could run an agent in a sandbox and ensure that any requests it makes to Github are authenticated. But it will never be able to access the credentials: **TypeScript** ```ts export class MySandbox extends Sandbox {} MySandbox.outboundByHost = { "github.com": (request: Request, env: Env, ctx: OutboundHandlerContext) => { const requestWithAuth = new Request(request); requestWithAuth.headers.set("x-auth-token", env.SECRET); return fetch(requestWithAuth); }, }; ``` You can easily inject unique credentials for different instances by using `ctx.containerId`: **TypeScript** ```ts MySandbox.outboundByHost = { "my-internal-vcs.dev": async ( request: Request, env: Env, ctx: OutboundHandlerContext, ) => { const authKey = await env.KEYS.get(ctx.containerId); const requestWithAuth = new Request(request); requestWithAuth.headers.set("x-auth-token", authKey); return fetch(requestWithAuth); }, }; ``` No token is ever passed into the sandbox. You can rotate secrets in the Worker environment and every request will pick them up immediately. #### TLS interception Outbound Workers now intercept HTTPS traffic. A unique ephemeral certificate authority (CA) and private key are created for each sandbox instance. The CA is placed into the sandbox and trusted by default. The ephemeral private key never leaves the container runtime sidecar process and is never shared across instances. With TLS interception active, outbound Workers can act as a transparent proxy for both HTTP and HTTPS traffic. #### Allow and deny hosts Easily filter outbound traffic with `allowedHosts` and `deniedHosts`. When `allowedHosts` is set, it becomes a deny-by-default allowlist. Both properties support glob patterns. **TypeScript** ```ts export class MySandbox extends Sandbox { allowedHosts = ["github.com", "npmjs.org"]; } ``` #### Dynamic outbound handlers Define named outbound handlers then apply or remove them at runtime using `setOutboundHandler()` or `setOutboundByHost()`. This lets you change egress policy for a running sandbox without restarting it. **TypeScript** ```ts export class MySandbox extends Sandbox {} MySandbox.outboundHandlers = { allowHosts: async (req: Request, env: Env, ctx: OutboundHandlerContext ) => { const url = new URL(req.url); if (ctx.params.allowedHostnames.includes(url.hostname)) { return fetch(req); } return new Response(null, { status: 403 }); }, noHttp: async () => { return new Response(null, { status: 403 }); }, }; ``` Apply handlers programmatically from your Worker: **TypeScript** ```ts const sandbox = getSandbox(env.Sandbox, userId); // Open network for setup await sandbox.setOutboundHandler("allowHosts", { allowedHostnames: ["github.com", "npmjs.org"], }); await sandbox.exec("npm install"); // Lock down after setup await sandbox.setOutboundHandler("noHttp"); ``` Handlers accept `params`, so you can customize behavior per instance without defining separate handler functions. #### Get started Upgrade to `@cloudflare/containers@0.3.0` or `@cloudflare/sandbox@0.8.9` to use these features. For more details, refer to [Sandbox outbound traffic](https://edgetunnel-b2h.pages.dev/sandbox/guides/outbound-traffic/) and [Container outbound traffic](https://edgetunnel-b2h.pages.dev/containers/platform-details/outbound-traffic/). Apr 13, 2026 1. ### [Local Explorer for local resource data](https://edgetunnel-b2h.pages.dev/changelog/post/2026-04-13-local-explorer/) [ Workers ](https://edgetunnel-b2h.pages.dev/workers/) Local Explorer is a browser-based interface and REST API for viewing and editing local resource data during development. It removes the need to write throwaway scripts or dig through `.wrangler/state` to understand what data your Worker has stored locally. Local Explorer is available in Wrangler 4.82.1+ and the Cloudflare Vite plugin 1.32.0+. Start a local development session and press `e` in your terminal, or navigate to `/cdn-cgi/explorer` on your local dev server. #### Supported resources Local Explorer supports five resource types and works across multiple workers running locally: * **[KV](https://edgetunnel-b2h.pages.dev/kv/)** — Browse keys, view values and metadata, create, update, and delete key-value pairs. * **[R2](https://edgetunnel-b2h.pages.dev/r2/)** — List objects, view metadata, upload files, and delete objects. Supports directory views and multi-select. * **[D1](https://edgetunnel-b2h.pages.dev/d1/)** — Browse tables and rows, run arbitrary SQL queries, and edit schemas in a full data studio. * **[Durable Objects](https://edgetunnel-b2h.pages.dev/durable-objects/)** (SQLite storage) — Browse individual object SQLite tables, run SQL queries, and edit schemas. * **[Workflows](https://edgetunnel-b2h.pages.dev/workflows/)** — List instances, view status and step history, trigger new runs, and pause, resume, restart, or terminate instances. #### OpenAPI-powered REST API Local Explorer exposes a REST API at `/cdn-cgi/explorer/api` that provides programmatic access to the same operations available in the browser. The root endpoint returns an [OpenAPI specification ↗](https://www.openapis.org/) describing all available endpoints, parameters, and response formats. ```sh curl http://localhost:8787/cdn-cgi/explorer/api ``` Point an AI coding agent at `/cdn-cgi/explorer/api` and it can discover and interact with your local resources without manual setup. This enables iterative development loops where an agent can populate test data in KV or D1, inspect Durable Object state, trigger Workflow runs, or upload files to R2. For more details, refer to the [Local Explorer documentation](https://edgetunnel-b2h.pages.dev/workers/local-development/local-explorer/). Apr 10, 2026 1. ### [Canvas Remoting optimizes performance for productivity applications](https://edgetunnel-b2h.pages.dev/changelog/post/2026-04-10-canvas-remoting-performance/) [ Browser Isolation ](https://edgetunnel-b2h.pages.dev/cloudflare-one/remote-browser-isolation/) Remote Browser Isolation now supports **Canvas Remoting**, improving performance for HTML5 Canvas applications by sending vector draw commands instead of rasterized bitmaps. #### Key improvements * **10x bandwidth reduction:** Microsoft Word and other Office apps use 90% less bandwidth * **Smooth performance:** Google Sheets maintains consistent 30fps rendering * **Responsive terminals:** Web-based development environments and AI notebooks work in real-time * **Zero configuration:** Enabled by default for all Browser Isolation customers #### How it works Instead of sending rasterized bitmaps for every Canvas update, Browser Isolation now: 1. Captures Canvas draw commands at the source 2. Converts them to lightweight vector instructions 3. Renders Canvas content on the client This reduces bandwidth from hundreds of kilobytes per second to tens of kilobytes per second. #### Managing Canvas Remoting To temporarily disable for troubleshooting: * Right-click the isolated webpage background * Select **Disable Canvas Remoting** * Re-enable the same way by selecting **Enable Canvas Remoting** #### Limitations Currently supports 2D Canvas contexts only. WebGL and 3D graphics applications continue using bitmap rendering. For more information, refer to [Canvas Remoting](https://edgetunnel-b2h.pages.dev/cloudflare-one/remote-browser-isolation/canvas-remoting/). Apr 10, 2026 1. ### [Browser Rendering adds Chrome DevTools Protocol (CDP) and MCP client support](https://edgetunnel-b2h.pages.dev/changelog/post/2026-04-10-browser-rendering-cdp-endpoint/) [ Browser Run ](https://edgetunnel-b2h.pages.dev/browser-run/) [Browser Rendering](https://edgetunnel-b2h.pages.dev/browser-run/) now exposes the [Chrome DevTools Protocol (CDP)](https://edgetunnel-b2h.pages.dev/browser-run/cdp/), the low-level protocol that powers browser automation. The growing ecosystem of CDP-based agent tools, along with existing CDP automation scripts, can now use Browser Rendering directly. Any CDP-compatible client, including [Puppeteer](https://edgetunnel-b2h.pages.dev/browser-run/cdp/puppeteer/) and [Playwright](https://edgetunnel-b2h.pages.dev/browser-run/cdp/playwright/), can connect from any environment, whether that is [Cloudflare Workers](https://edgetunnel-b2h.pages.dev/workers/), your local machine, or a cloud environment. All you need is your Cloudflare API key. For any existing CDP script, switching to Browser Rendering is a one-line change: **JavaScript** ```js const puppeteer = require("puppeteer-core"); const browser = await puppeteer.connect({ browserWSEndpoint: `wss://api.cloudflare.com/client/v4/accounts/${ACCOUNT_ID}/browser-rendering/devtools/browser?keep_alive=600000`, headers: { Authorization: `Bearer ${API_TOKEN}` }, }); const page = await browser.newPage(); await page.goto("https://example.com"); console.log(await page.title()); await browser.close(); ``` Additionally, MCP clients like Claude Desktop, Claude Code, Cursor, and OpenCode can now use Browser Rendering as their remote browser via the [chrome-devtools-mcp ↗](https://github.com/ChromeDevTools/chrome-devtools-mcp) package. Here is an example of how to configure Browser Rendering for Claude Desktop: ```json { "mcpServers": { "browser-rendering": { "command": "npx", "args": [ "-y", "chrome-devtools-mcp@latest", "--wsEndpoint=wss://api.cloudflare.com/client/v4/accounts//browser-rendering/devtools/browser?keep_alive=600000", "--wsHeaders={\"Authorization\":\"Bearer \"}" ] } } } ``` To get started, refer to the [CDP documentation](https://edgetunnel-b2h.pages.dev/browser-run/cdp/). Apr 10, 2026 1. ### [API tokens now detectable by secret scanning tools](https://edgetunnel-b2h.pages.dev/changelog/post/2026-04-10-secret-scanning-support/) [ Cloudflare Fundamentals ](https://edgetunnel-b2h.pages.dev/fundamentals/) Cloudflare API tokens now include **identifiable patterns** that enable secret scanning tools to automatically detect them when leaked in code repositories, configuration files, or other public locations. #### What changed API tokens generated by Cloudflare now follow a standardized format that secret scanning tools can recognize. When a Cloudflare token is accidentally committed to GitHub, GitLab, or another platform with secret scanning enabled, the tool will flag it and alert you. #### Why this matters Leaked credentials are a common security risk. By making Cloudflare tokens detectable by scanning tools, you can: * **Detect leaks faster** — Get notified immediately when a token is exposed. * **Reduce risk window** — Exposed tokens are deactivated immediately, before they can be exploited. * **Automate security** — Leverage existing secret scanning infrastructure without additional configuration. #### What happens when a leak is detected When a third-party secret scanning tool detects a leaked Cloudflare API token: 1. **Cloudflare immediately deactivates the token** to prevent unauthorized access. 2. **The token creator receives an email notification** alerting them to the leak. 3. **The token is marked as "Exposed"** in the Cloudflare dashboard. 4. **You can then roll or delete the token** from the token management pages. #### Supported platforms * **GitHub Secret Scanning** — Automatically enabled for public repositories For more information on token formats and secret scanning, refer to [API token formats](https://edgetunnel-b2h.pages.dev/fundamentals/api/get-started/token-formats/).

Previously, each Worker invocation was limited to six open connections at a time for the entire lifetime of each connection, including while reading the response body. Now, a connection is freed as soon as response headers arrive, so the six-connection limit only constrains how many connections can be in the initial "waiting for headers" phase simultaneously. #### Before: New connections are blocked until an earlier connection fully completes ![A 7th fetch is queued until an earlier connection fully completes, including reading its entire response body](https://edgetunnel-b2h.pages.dev/_astro/connection-limit-before.DA5Xnf2k_Z15lWkB.svg) #### After: New connections can start as soon as response headers arrive ![A 7th fetch starts as soon as any earlier connection receives its response headers](https://edgetunnel-b2h.pages.dev/_astro/connection-limit-after.BnN2EWxG_Z15lWkB.svg) This means Workers can now have many more connections open at the same time without queueing, as long as no more than six are waiting for their initial response. This eliminates the `Response closed due to connection limit` exception that could previously occur when the runtime canceled stalled connections to prevent deadlocks. Previously, the runtime used a deadlock avoidance algorithm that watched each open connection for I/O activity. If all six connections appeared idle — even momentarily — the runtime would cancel the least-recently-used connection to make room for new requests. In practice, this heuristic was fragile. For example, when a response used `Content-Encoding: gzip`, the runtime's internal decompression created brief gaps between read and write operations. During these gaps, the connection appeared stalled despite being actively read by the Worker. If multiple connections hit these gaps at the same time, the runtime could spuriously cancel a connection that was working correctly. By only counting connections during the waiting-for-headers phase — where the runtime is fully in control and there is no ambiguity about whether the connection is active — this class of bug is eliminated entirely. #### Before: Connections could be canceled during brief internal pauses ![A connection with gaps from gzip decompression appears idle and is canceled by the runtime](https://edgetunnel-b2h.pages.dev/_astro/connection-cancel-before.B6J6v5SX_ZdXLqG.svg) #### After: Connections complete normally regardless of internal pauses ![The same connection completes normally because the body phase is no longer counted against the limit](https://edgetunnel-b2h.pages.dev/_astro/connection-cancel-after.0sUzrfMs_2fzdYj.svg) Apr 08, 2026 1. ### [Website Source CSS content selectors for precise content extraction in AI Search](https://edgetunnel-b2h.pages.dev/changelog/post/2026-04-09-ai-search-content-selectors/) [ AI Search ](https://edgetunnel-b2h.pages.dev/ai-search/) [AI Search](https://edgetunnel-b2h.pages.dev/ai-search/) now supports [CSS content selectors](https://edgetunnel-b2h.pages.dev/ai-search/configuration/data-source/website/#content-selectors) for website data sources. You can now define which parts of a crawled page are extracted and indexed by specifying CSS selectors paired with URL glob patterns. Content selectors solve the problem of indexing only relevant content while ignoring navigation, sidebars, footers, and other boilerplate. When a page URL matches a glob pattern, only elements matching the corresponding CSS selector are extracted and converted to Markdown for indexing. Configure content selectors via the dashboard or API: ```bash curl "https://api.cloudflare.com/client/v4/accounts/{account_id}/ai-search/instances" \ -H "Authorization: Bearer {api_token}" \ -H "Content-Type: application/json" \ -d '{ "id": "my-ai-search", "source": "https://example.com", "type": "web-crawler", "source_params": { "web_crawler": { "parse_options": { "content_selector": [ { "path": "**/blog/**", "selector": "article .post-body" } ] } } } }' ``` Selectors are evaluated in order, and the first matching pattern wins. You can define up to 10 content selector entries per instance. For configuration details and examples, refer to the [content selectors documentation](https://edgetunnel-b2h.pages.dev/ai-search/configuration/data-source/website/#content-selectors).

This update allows security teams to automatically elevate a user's risk score when they visit high-risk or malicious domains, providing a more holistic view of internal threats. #### Why this matters Browsing activity is a primary indicator of potential compromise. By tying Gateway DNS logs to specific users, administrators can now flag individuals interacting with: * **Security threats**: Domains associated with malware, phishing, or command-and-control (C2) centers. * **High-risk content**: Categories such as questionable content or violence that may violate corporate compliance. Even if a Gateway policy is set to **Block** the traffic, the interaction is still captured as a "hit" to ensure the user's risk profile reflects the attempted activity. #### New risk behaviors Two new behaviors are now available in the dashboard: * **Suspicious Security Domain Visited**: Triggers when a user visits a domain in the security threats or security risk categories. * **High risk domain visited**: Triggers when a user visits domains categorized as questionable content, violence, or CIPA. To learn more and get started, refer to the [User Risk Scoring documentation](https://edgetunnel-b2h.pages.dev/cloudflare-one/team-and-resources/users/risk-score/).
