What is Open Source UI?
Open Source UI is a free UI library for React and Next.js with more than 200 MIT-licensed, copy-paste components, Tailwind CSS blocks, iPhone and MacBook mockups, Apple Watch frames and TypeScript source. Every component has a live preview at opensourceui.in, so you can see exactly what you are copying before dropping it into your own project.
Pros
- 200+ ready-to-use React and Next.js components
- Live previews for every component before copying
- MIT licensed for personal and commercial projects
Cons
- Focused on React/Next.js and Tailwind users; other stacks need adaptation
- Some premium-style finishes may require customisation for unique branding
Who should use Open Source UI
Developers, designers and indie builders who want free, copy-paste React and Next.js components with live previews and Tailwind-ready styling.
Who may not need it
Teams using a different frontend stack or those wanting a managed, hosted design system with ongoing support.
