Raco is a high-performance HTTP client for the terminal, designed for developers working on the command line. The tool integrates support for HTTP, WebSocket, and gRPC protocols in a three-panel interface operable with Vim-style keyboard shortcuts or a mouse.

Dual operation mode. Raco functions as a Textual User Interface (TUI) for interactive exploration and as a Command-Line Interface (CLI) for automation, scripting, and integration into continuous integration and continuous delivery (CI/CD) systems.
