### Social Sharing
- Twitter/X: "Tired of `lsof -i :3000 | kill -9`? Try `portctl fix 3000` -- identifies the process, checks safety, kills gracefully, suggests restart. Built in Rust, ~1.2MB. https://github.com/abhishekayu/portctl"
- Reddit r/rust: "I built portctl -- a CLI that replaces the lsof+kill workflow for fixing port conflicts. Written in Rust, classifies 13+ service types, has safety checks, and auto-restarts dev servers."
- Reddit r/webdev: "Every developer hits 'Port 3000 is already in use'. I built a CLI that fixes it in 3 seconds with safety checks and auto-restart."
- Hacker News: "Show HN: portctl -- Stop guessing what's running on your machine (Rust CLI)"
