Advanced REST Client17.0.9

Send requests to REST services and examine their responses while testing how an API behaves from a Mac. Advanced REST Client provides a desktop workspace for calling REST-based services, giving developers and other technical users a dedicated client for API testing. It is useful during API development when an endpoint or service needs to be exercised directly rather than through a finished application.

The software is aimed at developers, QA engineers, and technical teams who work with REST interfaces on macOS. Its central capability is sending requests to REST services and reviewing the resulting exchanges, keeping API checks in one desktop application. Documentation for the application is available through the project’s dedicated documentation site.

Advanced REST Client runs on MacOS with either Intel or Apple Silicon architecture, and the current version is 17.0.9. It is freeware, so the main installation consideration is choosing the build that matches the Mac hardware. Developers interested in contributing can also consult the application architecture and contribution guidance, install its development dependencies, and run the application from the development environment.
