RestApia

RestApia is a desktop client for constructing, sending, and inspecting HTTP requests against web APIs. It provides an interface where developers can define request methods, headers, query parameters, and body payloads, then view the full response including status code, headers, and body content. The tool supports saving and reusing request configurations, enabling iterative testing of API endpoints during development.

The application is packaged for macOS on Apple Silicon, with installers available as a PKG file or via Homebrew cask. It is positioned as a developer‑oriented utility for API testing, offering a graphical alternative to command‑line tools. The client is listed as stable and is part of a broader set of developer tools focused on HTTP interactions.

While the current distribution targets macOS, the project’s documentation mentions additional platforms such as Windows and Linux, though installers for those are not provided at this time. Users can consult the supported platforms guide for details on availability.
