Eclipse Theia

Open a real repository in Eclipse Theia with its language servers, terminal, debugger, and extensions. Complete a small bug fix, run tests, and measure startup and responsiveness in the desktop or browser deployment you intend to use.

If hosted remotely, test authentication, workspace persistence, file permissions, and recovery after the browser disconnects. Theia is a foundation for customizable IDEs; evaluate the complete setup your developers will receive, not an empty demo instance.
