Arc is a library of React components and blocks with motion built in. The core is free and open source (MIT) and installs with the shadcn CLI, so the code lives in your project and you can change anything. Every component has Markdown docs, llms.txt and an MCP server, so Claude Code or Cursor can pick and install the right piece instead of inventing one. Pro adds showpiece motion components and full app screens. New components ship every day.
Hi Product Hunt, I'm Elia.
I built Arc alone over the last months because every UI I shipped ended the same way: me rebuilding the same dialog, select and table until they finally felt right. Arc is the version I wanted to install once and stop rebuilding.
What makes it different:
• Motion is part of every component, not added on later. Opening, closing and interrupting all feel physical.
• The core is MIT and installs with the shadcn CLI, so you own the code.
• It's built for AI tools too. Every component has Markdown docs, and there's an MCP server, so your agent uses real components instead of guessing.
Pro adds the bigger showpiece components and full app screens, and it pays for my time.

I'd love your honest feedback, especially on what feels off or what's missing. I'll be here all day answering everything.
Hands down the best UI library I've come across - bought Pro instantly. Congrats on the launch!
Congrats on the launch, @kuratlielia ! Really like the attention to detail in the components, and animations feel smooth, definitely see the value in not having to rebuild these UI components. Great work!
