grpcui is a web UI tool for interactively calling gRPC servers from the browser, like Postman. It reads service and method definitions from server reflection or proto files and automatically generates input forms for request messages, supports specifying metadata and streaming calls, and displays responses as JSON. It pairs with grpcurl, a command-line tool from the same developer, and is written in Go and distributed as a single binary.
