Onlook

Onlook positions itself as the designer's counterpart to Cursor, providing a visual editor for live React codebases. You edit on an infinite canvas with AI help, staying in control of the output. The designer-first positioning sets it apart from developer-focused builders.

Being open-source and self-hostable means you own the setup, unlike closed-source alternatives, giving teams full deployment flexibility. For organizations wanting transparency and control over their tools, the open-source model is a genuine differentiator.
