Embed a live Linux desktop in any document

You write a tutorial in Notion about deploying a Python app. Instead of screenshots and a Loom video, you paste a URL into an iframe block. The iframe is a real Ubuntu desktop, running in a container, that the reader can click into and use.

They follow your tutorial on the actual desktop you're describing. They type the commands you wrote about. The terminal in the iframe responds. When they break it, they refresh the page and start over from the snapshot.

This works in Notion. It works in a Google Doc embed. It works in your product's onboarding modal. It works in a confluence page. It works in a tweet. Anywhere an iframe renders, a computer renders.

Documentation stops describing computers and starts being computers.
