KiCad… In The Browser? hackaday.com

Akshay Rukade created ZiroEDA, a browser-based TypeScript port of KiCad 10.0.6 that includes schematic and PCB editors, interactive routing, and electrical and design-rule checks. It can open and save KiCad project files; compatibility tests reportedly produced zone fills with vertices identical to KiCad’s, though the project is still a work in progress with some dialogs missing.
