grpcmd

What grpcmd is

grpcmd is a command-line tool for working with gRPC services on Linux, macOS, and Windows. It can use server reflection to find available services and methods, explain a method’s request and response messages, and send calls. Requests and responses can stream, with headers, message data, and trailers shown in output. If you prefer not to use reflection, you can supply .proto files and import search paths instead. grpcmd can also launch a server implementing grpcmd.GrpcmdService with reflection, and its documentation includes shell-completion setup for Bash, Zsh, fish, and PowerShell. The related grpcmd-script tool lets you write endpoint tests in JavaScript and check response headers, messages, and trailers; it is distributed as a binary and does not need Node.js. A separate open-source, local-first desktop app, grpcmd-gui, offers reflection-based method lookup, request headers, JSON templates, streaming, response headers and trailers, and themes. grpcmd is free; grpcmd-script is listed at $9 a year.
