HeyPCB is an AI PCB designer that runs in the browser. Tell Inky, our design agent, what the board should do. Inky picks the parts, draws the schematic, places and routes the board, and checks it with DRC, ERC and a circuit simulation before calling it done. You keep the KiCad project, plus the Gerbers, drill files, BOM, CPL and STEP a board house needs.

Add HeyPCB to Claude Code:
claude mcp add --transport http --scope user heypcb https://api.heypcb.ai/mcpor to Codex:
codex mcp add heypcb --url https://api.heypcb.ai/mcp && codex mcp login heypcbThen ask for a board in plain words, for example "a 40 × 20 mm USB-C board with an ATtiny85, four WS2812B LEDs and a button". Inky builds it on heypcb.ai and your agent can read, check and change it from there. Cursor and claude.ai are on heypcb.ai/mcp; the source is in heypcb-mcp.
- heypcb.ai: the full editor, with schematic, PCB, 3D and enclosure, each editable by hand. Free trial, no card needed.
- AI agents (MCP): design boards from Claude Code, Codex, Cursor or claude.ai.
- KiCad plugin: Inky beside the board open in KiCad 10's PCB Editor. In beta.
Also in the editor: Multiplayer (edit one board together, live), Time Machine (every edit by you, your team or Inky, and any version brought back in one step) and Comment (pin a question to any spot on the board).
These boards were designed with HeyPCB. Each repo has the KiCad 10 project, and most include Gerbers, BOM and CPL. Each repo names its licence.
