A suite of Go-based gRPC debugging tools, including grpc-dump (a transparent proxy that logs gRPC/gRPC-Web traffic as JSON), grpc-replay, grpc-fixture, and a reusable intercepting proxy library. It works like Fiddler or Charles but for gRPC, without requiring code changes to apps or servers.

Use cases

• debug grpc traffic between services
• dump grpc requests as a proxy like charles
• replay recorded grpc requests to a server
• mock grpc server responses from saved fixtures
• inspect grpc messages without proto files
• capture grpc-web requests with metadata

When to choose

• you need to inspect or debug gRPC traffic transparently without modifying application code
• you want to record and replay gRPC requests or serve fixture responses
• you lack .proto files but still need human-readable message dumps

When to avoid

• you need a mature, production-hardened tool - the project is explicitly in alpha with breaking changes
• you only need HTTP/REST debugging, where Fiddler or Charles are better fits
• you need actively maintained tooling - the latest release was in 2023
