GitHub·high signal

Onlook is an open-source AI-first design tool that provides a WYSIWYG layer directly on top of running Next.js + Tailwind CSS projects. Designers can select, drag, resize, recolor elements or describe changes in plain English, with changes syncing to .tsx and .css files in real-time and submitted as PRs. Apache 2.0 licensed with real-time collaboration, spatial comments, and self-hosting — bridging the designer-developer gap with live code editing rather than static mockups.
