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.
