## What it is
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

## Facets
- artifact type: cli-tool
- maturity: maintenance
- function: proxy, rpc, middleware, logging
- domain: developer-tools, apis, networking, testing
- platform: windows, go, cli
- tags: grpc, grpc-debugging, traffic-dumping, request-replay, charles-for-grpc, debugging, linux, macos
