Composter

The problem

Developers build the same navbar, modal and pricing table over and over. The good versions are buried in old repos, so they copy and paste from memory or rebuild from scratch.

The insight

Components need a home, like a password manager but for UI, reachable from wherever the developer is working, including the AI tools they now code with.

What we built

A full product with three ways in: a web dashboard with live component previews and one-click copy; a CLI (composter-cli on npm) to push and pull components from the terminal; and an MCP server (composter-mcp on npm), so assistants like Claude, Cursor and GitHub Copilot can fetch your components directly.

Under the hood

• Turborepo
• React
• Vite
• Tailwind
• shadcn/ui
• Node.js
• Prisma
• PostgreSQL
• Better Auth
• Sandpack
• npm packages (composter-cli, composter-mcp)

What it proves

We can take an idea from zero to a shipped, multi-surface product that real developers use.
