We're building Signex — an open-source, AI-first electronics design automation tool.
Signex is a KiCad-compatible schematic and PCB editor built in Rust with GPU-accelerated rendering. It aims to deliver Altium Designer-quality UX on top of the open KiCad file format — so engineers get a better editor without leaving the ecosystem they trust.
Two editions from one codebase:
- Signex Community (Apache-2.0) — full schematic editor, PCB editor with interactive routing and DRC, 3D viewer, simulation, plugin system. Free forever.
- Signex Pro (subscription) — adds Signal AI (Claude-powered design copilot), real-time collaboration, and Signex 365 cloud PLM.
We're currently building v0.6 (full schematic editor). The schematic viewer, editor, and canvas are working. Next up: ERC validation, PDF/BOM output, then PCB.
