Subframe

Subframe is a code-first UI builder where every layer maps directly to React and Tailwind components — no mockup-to-code translation gap. It ships 200+ pre-built components, design system support, and clean code export you actually own. A standout feature is MCP integration with Cursor and Claude Code, letting developers prompt new designs from their IDE. Aimed at backend-heavy teams that need to ship quality UI without a dedicated designer.
