A Go library of gRPC middleware (interceptors) providing chained, ready-to-use implementations for auth, logging, tracing, metrics, retries, recovery, and more. It is the official grpc-ecosystem collection for building consistent cross-cutting concerns across gRPC servers and clients.

Use cases

• chain grpc interceptors in go
• add authentication to grpc server
• add logging and tracing to grpc services
• grpc retry and rate limiting middleware
• add prometheus metrics to grpc
• recover from panics in grpc handlers
• build consistent observability across microservices

When to choose

• you build gRPC services in Go and need standard cross-cutting middleware
• you want consistent logging, tracing, and metrics instrumentation across multiple microservices
• you need chained interceptors for auth, retries, and panic recovery

When to avoid

• you use a non-Go language (see language-specific gRPC middleware instead)
• your framework is HTTP/REST rather than gRPC
• you need highly custom interceptor behavior beyond what the provided middlewares offer
