Cocoa Rest Client

The application provides a native macOS interface for constructing and sending HTTP requests such as GET, POST, PUT, DELETE, and HEAD. Users can configure request headers, authentication (Basic or Digest), and body content either as raw text, parameter lists, or multipart file uploads. Responses are displayed with automatically formatted XML or JSON, and response headers are shown alongside a unified diff tool for comparing results.

It stores request URLs, bodies, and headers in a drawer for quick reuse, supports SSL including untrusted certificates, and can follow redirects optionally. Memory usage is low, and the tool includes syntax highlighting and Base64 encoding utilities. The software runs on macOS 10.12 and newer and is distributed under the New BSD License.

Developers who need a lightweight, open‑source alternative to command‑line tools for testing RESTful APIs on Apple platforms will find it useful. Contributions are accepted via GitHub, and updates are delivered through an integrated auto‑update mechanism.
