What is LangUI?

LangUI is an open‑source Tailwind CSS component library for AI and GPT projects. It provides more than 60 ready‑made, fully responsive components that support dark and light modes. Components require zero dependencies and can be added with a simple copy‑paste, removing installation overhead.

A two‑color palette of slate and blue enables easy customization to match brand or design systems. The MIT license allows free use in personal and commercial projects. Hosted on GitHub, the library encourages community contributions and lets users request new components via issues.

LangUI streamlines UI development for web developers building AI interfaces, saving time while maintaining visual consistency. It integrates with modern frontend stacks and can be extended by adding Tailwind classes. Comprehensive documentation and code examples aid rapid prototyping and deployment.
