Spaceman
A cross-platform gRPC client for manual testing and debugging, available as both a desktop GUI and CLI.
What is Spaceman?
Spaceman is a cross-platform gRPC client designed for manual testing and debugging of gRPC servers. It allows developers to load Protobuf descriptors, choose requests, fill input message bodies, and send them easily. The tool solves the problem of interactively testing gRPC services without writing custom code.
Developers and engineers working with gRPC-based services who need a tool for manual testing, debugging, and exploration of APIs. It's particularly useful for those in small teams or projects where Protobuf schemas serve as documentation.
Spaceman offers a dual GUI and CLI interface built entirely in Rust, ensuring performance and cross-platform compatibility. Its integration with Protobuf provides strong typing and schema-based editing, making gRPC testing more intuitive compared to generic HTTP clients.
