grpcc - gRPC CLI testing tool

grpcc is a Node.js command-line tool for interacting with gRPC servers, enabling rapid testing and debugging of gRPC services without writing client code. Version 1.1.3 (latest) offers a simple REPL interface that loads .proto files and provides autocomplete for gRPC calls. Key differentiators: no need to write a client program, supports streaming RPCs, and uses Node.js REPL for interactive exploration. Currently in maintenance mode with sporadic updates, but remains functional for Node.js-based gRPC testing.
