A blank canvas, an existing screenshot, or a text prompt describing what you want.
Drag, drop, and edit with real components — what you see is actual code underneath.
Generate layouts from screenshots or prompts, then refine by hand where it matters.
Ship clean React/Tailwind/CSS you can actually maintain, not a dead mockup.
Design directly on the canvas with real components and styles.
Screenshot-to-code and prompt-to-UI that produce editable results.
Exports are maintainable codebases, not locked-in proprietary files.
Multiplayer editing and commenting for teams.
Your design files live on your infrastructure.
No proprietary lock-in on your own work.
Download the source and move into the project folder.

It is an open-source project at onlook-dev/onlook with 2,116 forks. Check the repo's contributors and recent commits to see how active maintenance is.
Typically React with Tailwind or plain HTML/CSS, depending on the tool.
The open-source tools here are free to use and self-host.
