Onlook

Onlook: Onlook Overview

Onlook is an open-source visual editor for React and Tailwind apps that lets you design directly on your live codebase. Edit styles, layout, and content visually in the browser and Onlook writes the changes back to your real code — closing the gap between design and development.

Key Features

1. Design on real code: Manipulate live React components visually, with edits saved to source.
2. Tailwind-aware: Adjust spacing, color, and type and get clean Tailwind classes.
3. AI assistance: Generate and refine UI with prompts on top of your project.
4. Open source: Self-hostable and transparent, built for developer trust.

Who It's For

Onlook is for people who live between design and code:

• Frontend developers who want a visual layer
• Designers comfortable working in React projects
• Founders iterating on their own product UI
• Teams wanting design changes committed as code

Conclusion

Onlook treats the codebase as the source of truth, giving design-minded builders a visual canvas that produces real, mergeable React code instead of throwaway mockups.
