4 sourcesShow HN: OpenPencil - Open-source vector design tool controlled by AI Agents
Hey! I'm the creator of OpenPencil, and I'm super excited to share it with you today.
We are entering the era of AI Agents, but our design tools are still stuck in the GUI era. We are constantly downloading "final_v9.fig" and manually clicking to tweak UI elements. I wanted to change that.
OpenPencil isn't just another design tool with a magic AI button. It is structurally built for AI.
Here is why it's different:
Agentic Design (MCP Server): You can connect Claude, Cursor, or any MCP-compatible agent directly to your design. Tell your AI IDE to "update the login screen to match the new dark mode theme," and it modifies the design file without you ever touching a mouse.
Design-as-Code: The .op format is pure JSON. Finally, you can Git commit, diff, and PR your design files just like your codebase.
100% Open Source (MIT): No subscriptions,

no vendor lock-in. Build on top of it, fork it, make it yours.
I built this because I believe the future of design is Human creativity + Agent execution.
I'd love your feedback! Drop your questions below, and let me know what features you want to see next!
