BloomRPC

GUI client for gRPC, REST and WebSocket APIs with innovative features for environments, authorizations and more

It is a modern, minimalist type-safe gRPC framework for Node.js. It has @grpc/grpc-js as a dependency, so no further production dependencies are required. You will need to generate JavaScript (optionally TypeScript) stubs from your proto files. These will be generated before the start of the app and are usually development dependencies.

It is an open-source gRPC client, an alternative to Postman and Insomnia. It works with your requests in a multi-tabs way, it is a fully-featured desktop gRPC/gRPC-Web client that makes your development experience effortless.
