About:
The go-feature-flag-relay-proxy is a standalone server that acts as a high-performance intermediary for GO Feature Flag clients. It caches flag evaluations and reduces latency by handling requests locally instead of calling the central API for every check. This proxy is essential for scaling feature flag usage in distributed systems and serverless environments.
Key Features:
  • High-performance evaluation caching
  • Reduces load on the central GO Feature Flag API
  • Supports OpenTelemetry for distributed tracing
  • Easy deployment as a sidecar or standalone service
Use Cases:
  • Reducing latency in feature flag checks for high-traffic applications
  • Scaling feature flag usage in serverless or edge computing environments
  • Centralizing flag management for multiple downstream services
Alternatives:
  • Unleash Proxy – Similar concept for Unleash, but specifically designed for the GO Feature Flag ecosystem
  • Local Flag Evaluation – Embedding the SDK directly; the proxy offers centralized caching and reduced SDK overhead
