Onlook
The Developer Tool for Designers
Onlook is a free, open-source visual editor for React and Tailwind CSS applications. It addresses the disconnect between design and development by allowing designers to edit components visually in the browser, with the tool updating the actual code files in real time. This approach ensures the code remains the source of truth, turning visual edits into production-ready code rather than static mockups.
The editor provides an infinite canvas with drag-and-drop functionality, direct element manipulation, and a layer panel for navigating the React component tree. It includes an AI assistant that can generate and iterate on UI components, understanding existing React components and design tokens. Key capabilities include a component library for reusable elements, centralized theming and brand management, automatic version history, and support for importing existing React or Next.js codebases. The tool is built for designers and teams working with React and Tailwind CSS.
Onlook is open source and can be self-hosted for free. A hosted cloud version is available in closed beta. The product is packaged with a free tier, and the website indicates a waitlist for access.
