About:
flagd is a feature flag daemon that provides a unified API for evaluating feature flags across various providers.

The tool is designed to be lightweight and follows Unix philosophy principles.

- Multiple protocol support (gRPC, HTTP, JSON-RPC)
- Declarative configuration via YAML/JSON
|
Use Cases:
