What Restfox is

Restfox is a free, open-source client for testing HTTP and socket connections, designed for web and desktop use. The web app supports HTTP, GraphQL, and WebSocket requests. Plugins can alter request and response data, set environment variables from responses, and run tests; they can also read or change methods, URLs, headers, query parameters, bodies, and response data. JavaScript automation scripts can assert API behavior, and a plugin can save values such as an access token for later requests. The interface includes response history, while collection exports support Restfox, Postman, and Insomnia formats. Desktop installation options cover macOS, Windows, and Linux distributions. Self-hosting instructions use Docker or Docker Compose, with port 4004 as the default. GitHub identifies the project as MIT-licensed. The free Restfox plan includes web and desktop access and Docker deployment. One documented plugin method for reading a local file is desktop-only.

Who it suits

It suits developers testing APIs and socket connections across web or desktop environments. Teams needing scripts, plugins, collection exports, or self-hosting can use the listed capabilities.

Verdict

Restfox combines API request tools, scripting, plugins, history, and collection export in a free open-source package. Its desktop-only local-file method is the main documented limitation for cross-platform workflows.
