Know exactly what's running on every port of your Mac

Portero is a free, open source Mac app that shows every open port and the process behind it. See what's running, kill processes on busy ports, fix 'address already in use' errors, and block ports with the built-in macOS firewall.
Are you planning to support deep Docker integration where Portero queries the local Docker socket? If we could resolve a generic docker-proxy process down to the exact container name and Docker Compose service, this would instantly become a must-have tool for local microservice debugging.
the visibility ceiling is worth spelling out — unprivileged lsof only sees sockets owned by your own uid, so a root daemon listening on a port stays invisible until the app escalates. for a dev tool that's fine. tagged as security software, that's exactly the port you'd want to see.
Congrats @ctresb on the launch, "Which node?" is the whole developer experience in two words, I've killed the wrong process on the wrong project more times than I'll admit.
Can't you view and terminate processes using the built-in macOS tools? As far as I remember, you can't manage ports, but you can manage processes.
It doesn't work; it detects it as malware.
Turning port management into a visual, one click experience is such a smart touch, especially building on the native macOS firewall instead of reinventing it.
