About:
grpcui is a command-line utility that presents a web UI for gRPC services. It inspects a gRPC endpoint via reflection and renders an interactive form for making RPC calls. This allows developers to test and debug gRPC APIs in a browser, similar to how Postman is used for REST.
Key Features:
  • Automatic discovery of gRPC services via reflection
  • Interactive web UI for constructing and sending requests
  • Support for TLS and custom credentials
  • Displays responses and metadata in a readable format
Use Cases:
  • Debugging gRPC API endpoints during development
  • Manually testing gRPC services without writing client code
  • Inspecting the API surface of a gRPC server
Alternatives:
  • grpcurl – grpcurl is the command-line counterpart for making gRPC calls, while grpcui provides a graphical web interface.
