OTF

OTF is a production-ready component library offering 215+ cross-platform UI components with a single API for both web and native development. Built on Radix primitives and designed for React, Expo, TypeScript, and Tailwind CSS, OTF provides composable, unstyled components that developers can customize and own entirely.

The library includes a live Storybook, Figma integration, and specialized AI configurations for Cursor, Claude Code, and Lovable, enabling AI agents to read the documentation like code and generate complete screens from day one. Components cover essential UI needs including buttons, charts, commands, metrics, badges, kanban boards, calendars, and more advanced features like Gantt charts and color pickers.

OTF is ideal for developers and teams building full-stack applications who want to eliminate repetitive component coding, maintain code ownership, and leverage AI-assisted development. The MIT-licensed, open-source project offers free component browsing and kits with a 15% founding discount for early adopters.
