## Manage Flagship from the command line with Wrangler

Jul 16, 2026 

[ Flagship ](https://edgetunnel-b2h.pages.dev/flagship/) 

**[Wrangler](https://edgetunnel-b2h.pages.dev/workers/wrangler/)** now includes `wrangler flagship`, a command suite for managing [Flagship](https://edgetunnel-b2h.pages.dev/flagship/) apps and feature flags from your terminal.

Create an app and, if you use it from a Worker, add it to your `wrangler.json` or `wrangler.jsonc` file as a binding:

```bash
wrangler flagship apps create "My Worker App" \
  --binding FLAGS \
  --update-config
```

Then create flags for the behavior you want to control. Flags can be booleans, strings, numbers, or JSON values:

```bash
wrangler flagship flags create <APP_ID> new-checkout


wrangler flagship flags create <APP_ID> checkout-flow \
  --variation control=old-checkout \
  --variation treatment=new-checkout \
  --default control \
  --type string
```

After a flag exists, change its default variation or use enable and disable commands as kill switches. Existing targeting rules continue to apply unless you change or clear them explicitly:

```bash
wrangler flagship flags update <APP_ID> checkout-flow --default treatment
wrangler flagship flags disable <APP_ID> checkout-flow
wrangler flagship flags enable <APP_ID> checkout-flow
```

For release workflows, use `rollout`, `split`, and `rules` to change exposure without redeploying your Worker:

```bash
wrangler flagship flags rollout <APP_ID> new-checkout \
  --to on \
  --percentage 25 \
  --by user_id


wrangler flagship flags split <APP_ID> checkout-flow \
  --weight control=80 \
  --weight treatment=20 \
  --by user_id


wrangler flagship flags rules update <APP_ID> checkout-flow \
  --priority 1 \
  --when "country equals US"
```

These commands can also be used from CI/CD pipelines, scripts, and AI agents to inspect Flagship state, update flag behavior, or roll back changes through Wrangler.

Refer to the [wrangler flagship command reference](https://edgetunnel-b2h.pages.dev/flagship/reference/wrangler-commands/) for the full command guide.
