Caret

Caret is an AI design-to-code tool that keeps your design layer inside the git repository as real React components, built for developers and design-engineers who are tired of design files drifting out of sync with the app they ship. Rather than exporting from a separate design file, Caret stores design as actual .tsx files in a .caret/ directory that tracks alongside your code, so a fix you make once stays fixed tomorrow. You edit on a live canvas where React components render directly, and you manage design tokens for color, typography, spacing, and border radius in the same place. Caret integrates with AI coding agents through MCP, working with Claude Code and Cursor to sync design changes into your application. Its framework-agnostic sync translates React designs out to Next, Remix, Vue, Svelte, and Rails, so the design source does not lock you to one stack. The whole thing runs locally with no cloud account and no code transmitted off your machine, which matters for teams with source-control or privacy constraints. Caret is open source under Apache-2.0 and free. For teams looking for the best AI for design-to-code without rebuilding components by hand, it collapses the gap between the design canvas and the repo.
