Restfox

Restfox is a REST client designed for the web that emphasizes offline‑first operation. It lets users construct and send HTTP requests, inspect responses, and manage collections of endpoints without requiring a constant network connection. When connectivity is restored, any pending requests can be synchronized automatically.

The application runs natively on macOS, providing a desktop experience tailored to that platform’s conventions and performance characteristics. Its stable release status indicates that core functionality such as request editing, header configuration, and response viewing is fully implemented and reliable for regular use.

Targeted at developers, testers, and anyone who needs to interact with RESTful APIs, Restfox offers a straightforward interface for crafting queries, handling authentication, and reviewing server replies, all while supporting work in environments where internet access may be intermittent or unavailable.
