Zwaggen Desktop

Coming Soon

Zwaggen Desktop is in active development and will be released soon. Watch the GitHub repository for the announcement.

A native desktop app for editing specs and running requests against any API, with no CORS limitations. The hosted Zwaggen Web is great for browsing the spec builder UX and generating specs, but every cross-origin request hits browser CORS — which most APIs reject without explicit allow-list rules. Zwaggen Desktop runs requests through the OS network stack instead, the same way curl or Postman does.

Why you'll want it

• CORS-free API testing — point an endpoint at any URL and run it. No proxy, no extension, no browser flag, no server-side allow-list. The request goes out the same way curl does.
• Native file dialogs — open and save .zwag specs with your OS's real picker.
• .zwag file association — double-click a spec in Finder/Explorer to open it in Zwaggen.
• Recent files in the File menu — backed by the OS recent-docs surface (macOS dock right-click, Windows jump list).
• Cross-platform — macOS (Intel + Apple Silicon), Windows, Linux.
• Local-first, no telemetry — your specs stay on your disk; nothing phones home.

Until it ships

Use Zwaggen Web for spec editing and demo requests, plus the @zwaggen/cli for headless / CI runs. Both work today.
