The OpenFeature specification defines a vendor-agnostic, community-driven API standard for feature flag evaluation, maintained as a CNCF incubating project. This repository contains the normative requirements (RFC 2119 style) that SDKs and providers across languages must conform to.
Use cases
- standardize feature flag evaluation across vendors
- avoid vendor lock-in when switching feature flag tools
- build a conformant OpenFeature SDK for a new language
- implement a custom feature flag provider
- understand requirements for feature flag evaluation context and hooks
- unify multiple flag management systems behind one API
When to choose
- you want a common, vendor-neutral API for feature flagging across your stack
- you are building or certifying an OpenFeature SDK or provider
- you need to switch or consolidate feature flag platforms without refactoring code
When to avoid
- you need a runnable feature flag service or UI rather than a specification
- you want a single-vendor feature flag solution with batteries included
- you need flag storage, admin dashboards, or audit trails - the spec only defines the client evaluation API
