Hey HN! We built
https://harnesshive.com, a browser based tool to help you design wiring harnesses together.
HarnessHive has three key features 1) multiple engineers editing the same harness in real time 2) BOM and drawings that stay in sync automatically and 3) AI-native agent + MCP to assist designing.
We hope HarnessHive can make harness design less painful than Excel and Visio for some of you :). Let me know if you have any questions/comments/feature requests!
