Web & Desktop App
Stoplight has a desktop app! Download the appropriate version here.
Web or Local?
The main difference between the Stoplight desktop app and the web app is that the desktop app can store requests and test data offline. The desktop app can also connect with APIs that are behind firewalls or otherwise not available on the public internet (localhost as well).
When you start the Stoplight desktop app, it will start an instance of Prism on http://localhost:4010. The desktop Prism instance is identical to the downloadable Prism binary run manually from your terminal. When you run local tests in the desktop app, it automatically calls a local Prism instance with the correct arguments and spec files.
