Project history and usage
GO Feature Flag Relay Proxy is the server component of GO Feature Flag, an open-source feature flag system written in Go. The relay proxy exposes feature-flag evaluation APIs so applications in several languages can use GO Feature Flag through OpenFeature providers or direct HTTP calls.
Project history
The parent GO Feature Flag repository was created in 2020 as a Go-oriented feature flag library. Its README explains that the project began as a solution for the Go language and later expanded through OpenFeature standardization, with the relay proxy providing an API layer over the Go module so non-Go applications could share the same evaluation logic.
Adoption history
The project sits in the OpenFeature ecosystem and advertises provider support across backend, frontend, and mobile languages. Its adopters list includes organizations and open-source projects using it for backend services, frontend applications, OpenFeature-based flagging, and relay-proxy deployments.
How it is used
Practitioners run the relay proxy as the central flag-evaluation service, usually with a YAML configuration file passed through `--config` or mounted into a container. The proxy loads flag definitions from retrievers such as files, HTTP, S3, or Kubernetes, stores them in memory, polls for changes, and exposes APIs that OpenFeature SDK providers call from application code.
Why package nerds care
For package maintainers, the relay proxy is the packaged operational face of a library-first Go project. Shipping it as a Homebrew formula gives developers a database-free feature-flag daemon they can install locally for testing, wire into containers, or run as infrastructure beside services.
