CopperRoute, a PCB autorouter that stays in the browser
An open-source browser tool that routes KiCad and Specctra circuit boards locally, then exports the result as PCB, SES, or SVG files.
Field notes
CopperRoute accepts KiCad PCB and Specctra DSN files, applies either project rules or manually entered dimensions, and produces routed-board downloads alongside an SES session for returning the work to a source editor. The examples span small and comparatively dense boards, from Hubble jacks with 9 nets to a real-time chess board with 225. The page explicitly excludes several geometry types, including cutouts and custom pads, and advises refilling zones and running KiCad DRC afterward.
