Port Radar for macOS

Port Radar is a free, open-source macOS menu bar utility that surfaces every localhost server listening on a Mac, groups processes by project, lets developers stop or force quit them, and adds an on-device Apple Intelligence layer to explain what each process is and whether it is safe to stop. It also offers one-click Cloudflare Tunnel sharing for local previews. The website frames it around a clear daily developer pain: forgotten Vite servers, mystery ports, and random node processes eating CPU. Revenue, growth, and team size are not publicly disclosed, and no pricing page or paid plan is visible. As a product, it is polished and strongly positioned; as a business, it currently behaves like an open-source utility or top-of-funnel tool rather than a monetized startup.
