Onlook reimagines the React development experience by providing a visual editing layer that sits on top of real codebases. Designers and developers can select elements, modify styles, adjust layouts, and add components through a visual interface while the tool generates clean React code that integrates directly into the project repository. Unlike design-to-code tools that produce throwaway markup, Onlook works with existing code.
The platform supports both greenfield projects and brownfield codebases, meaning teams can adopt it for new features without rewriting existing applications. AI assistance helps generate component variations, suggest layout improvements, and convert visual changes into idiomatic React patterns. The open-source architecture with 22,000+ stars ensures transparency and community-driven development.
Onlook experienced 275% organic growth in late 2025, signaling strong market validation for the visual-first development approach. SaaS subscription plans include Pro and Enterprise tiers with team collaboration features. The tool focuses on producing maintainable code over one-off hacks, making it suitable for production applications rather than just prototyping.
