Wishmock

Wishmock is a gRPC and Connect RPC mock server (v0.9.9, released monthly) with hot reload, rule-based responses, built-in protovalidate support, and native gRPC-Web without a proxy. It runs as a global CLI, auto-creates project structure, and features a Web UI, Admin API, and MCP server for AI integration. Compared to alternatives like grpc-mock, it offers Connect RPC support and TLS/mTLS out of the box.
