Altium Designer

Altium Designer is a comprehensive PCB design platform used by professional engineers for schematic capture, layout, and manufacturing output. It offers strong supply-chain integration through ActiveBOM and part-sourcing panels that surface stock and pricing from major distributors. While it lacks SnapMagic's natural-language circuit chat, Altium provides rule-driven automation and extensive component libraries. Pricing follows a subscription model that is higher than many startups expect, making it a fit for larger teams needing enterprise features rather than lightweight AI copilots.
