Cartero

Compose HTTP requests and inspect API responses in a native desktop client.

Cartero is a graphical HTTP client for testing web APIs. It lets users configure request methods, headers, and body payloads, bind variables, and save requests in text-based TOML files for reuse.

The application is implemented in Rust with GTK4 and libadwaita. Its workspace separates HTTP handling, request-file formats, and interface objects into Rust crates.
