Best alternatives to Sonar in 2026
Every developer has been there: you try to start your dev server and get "port 3000 already in use," so you go hunting with lsof or ss to figure out what's squatting on that port, then kill it by PID. Sonar turns that whole ritual into a single readable command — it shows you every service listening on localhost, what process owns it, and lets you kill it directly, with extras like Docker container names and resource usage baked in. Sonar is a free, MIT-licensed, Go-based CLI (worth noting: it has no relation to SonarQube, the code-quality/security-scanning product from SonarSource — same-ish name, completely different tool). It works cross-platform using each OS's native tools under the hood (lsof on macOS, ss on Linux, netstat on Windows), and beyond basic port listing it shows CPU, memory, thread count, uptime, and health-check status for each service, can kill single processes or filtered groups (by Docker project, by user, with confirmation skipping), tails logs, and even opens a shell into a running container. There's an optional native Swift menu bar app for macOS if you want the same information without opening a terminal.
