About Onlook

Onlook is an open-source, visual-first code editor for building websites, prototypes and designs in Next.js and Tailwind CSS. Edits are made directly on the browser DOM with a Figma-like interface, while the changes are written to real code, so design and development share one source of truth.

You can create a Next.js app from text or an image or start from templates, then edit it visually, manage brand assets and tokens, create pages, browse layers and manage images. Developer tools include a real-time code editor, checkpoints you can restore, branching for design experiments, a CLI, an app marketplace, one-click deploys, shareable links and custom domains. Team collaboration is on the roadmap.

The README describes this repository as the open-source editor that started Onlook, while the hosted product for AI-native designers is in early access through a waitlist. It is licensed under Apache-2.0 and presented as an open alternative to tools such as Webflow, Figma Make, V0, Replit Agent, Lovable and Bolt.new. It suits designers who want to ship real code and developers who want a visual layer.
