I replaced lsof, ss, and netstat with a single Rust binary

The problem Every developer has been here: something is hogging port 3000 and you need to find out what. On Linux you try ss -tlnp | grep 3000 . On macOS it's lsof -i :3000 . On Windows... good luck. Each gives different output, different flags, and none of them tell you how long the process has been running, how much memory it's eating, or whether it's a Docker container. I got tired of this. So I built portview . One command, everything you need $ portview That's it. Every listening port, the process behind it, PID, user, uptime, memory usage, and the full command -- in a colored table. Cross-platform. ~1.3 MB single binary. Zero runtime dependencies.
