stitch-kit

Your coding agent designs terrible UI. stitch-kit wires it into Google Stitch MCP and teaches it the whole pipeline — ideation, screen generation, design systems, production components. Maintained by gabelul on GitHub, where it has earned 39 stars from the community.

It's actively developed around claude-code, claude-code-plugin, design-to-code, and is a solid reference for anyone building with these tools.
