Cloudflare's feature flag service.
About
- Cloudflare's feature flag service for controlling which features are exposed without redeploying code
- Flags are defined with targeting rules and percentage-based rollouts and are evaluated directly through a native Workers binding. Provides type-safe methods and automatic fallback to default values
- OpenFeature-compatible. The
@cloudflare/flagshipSDK works as an OpenFeature provider in Workers, Node.js, and the browser, so you can switch from another provider with a one-line config change - Targeting on user attributes supports 11 comparison operators, AND/OR groups, and sequential evaluation. Consistent hashing always gives the same user the same value
- Variant values can be booleans, strings, numbers, or JSON objects; object variants let a single flag deliver an entire configuration block
- Flags are created, edited, and deleted in the Cloudflare dashboard and managed per app, which corresponds to a project or service
- Uses the Workers KV infrastructure to deliver flag configuration
