Open-source AI platform Copperhead automates KiCad circuit board design and verification
↗
Copperhead provides an open-source AI agent that edits KiCad files, runs checks, and commits verified hardware changes automatically.
By enforcing a gate-based workflow, it ensures that no change is committed until KiCad’s ERC and DRC checks pass, eliminating drift between design and documentation. The CLI is free and runs locally, while paid Cloud and Team tiers add hosted runs, a web viewer, and CI integration for private repositories. Teams can thus treat hardware development as a software-like process with automated verification and traceable decision logs.

The CLI is free, Apache-2.0 licensed, runs locally on KiCad files without metering and requires only a user-provided LLM key.
Cloud ($49per user / month) and Team ($49per user / month + $199 / mo platform) tiers provide hosted runs, web viewer, ERC/DRC status, run history, and CI bot integration.
Each stage of the workflow acts as a gate, specification, architecture, parts, schematic, layout, outputs, firmware, and dev plan, so work is only committed after its validation passes.
