Ship your desktop app to the web by changing nothing

You built a Linux desktop app. Now everyone wants it "in the browser": which usually means an Electron rebuild or a year-long web port.

Or: install the app, unmodified, in a container. Launch it on a display. That display is a URL, and the URL is your app running in a browser tab: same binary, same toolkit, same pixels. Spin a fresh container per trial user so nobody shares state, and put the demo behind a "Try it now" link on your landing page. Visitors are inside the real product in seconds, with nothing downloaded and nothing to uninstall when the trial ends.

Your codebase has no idea any of this happened.
