BloomRPC is a graphical user interface client for discovering, testing, and querying gRPC service endpoints. It functions as an API tester that allows for sending requests and validating responses through a visual interface without the need to write manual client code.
The tool supports service discovery via the gRPC reflection API or by parsing protobuf definition files to generate request and response structures. It translates human-readable JSON input into binary protobuf format and utilizes an HTTP/2 transport layer to communicate with backend services.
The application provides capabilities for API exploration, service testing, and client development prototyping. It is delivered as a cross-platform desktop application.
