(tscircuit maintainer here) It might be easier to think of tscircuit as an electronics CAD kernel. We're MIT licensed and web-compatible, so we would make a great foundation for people building new EDA tools or people who would like to generate electronics (think domain-specific tools, e.g. a website that allows you to quickly build a custom keyboard)

FWIW In this case I think this board called out to freerouting for the routing. Companies have reached out to us with autorouting APIs, so we'll support different vendors and hopefully allow enough constraint-specification for people to get good results. Autorouting is important for reusability, even if it's routing between manually-routed sections (e.g. fanouts)
