Recoil

Every developer has been there: you try to start your local dev server, and you get that dreaded error: Port 3000 is already in use.

For years, my workflow was the same:

1. lsof -i :3000

2. Scour the terminal output for the PID.

3. kill -9 <PID>

4. Repeat for the next ghost process.

It’s a small friction, but when you do it 10 times a day, it adds up. I wanted a way to "snipe" these processes instantly without leaving my mouse or opening a terminal.

Enter Recoil I decided to build Recoil—a tactical system monitor that lives in your tray. It lists all active TCP listeners and gives you a literal "Sniper Button" to terminate them with zero friction.

The Tech Stack (The "How") I chose a stack that focuses on being lightweight and fast:

• Tauri v2 + Rust: I wanted to avoid the memory bloat of Electron. Recoil runs with a tiny footprint and handles system-level process management through a low-overhead Rust core.

• React + Tailwind: To give it that "tactical" dark-mode aesthetic that feels like a professional engineering tool rather than a generic utility.

Why I’m sharing this here I just released v1.4.3 and I’m looking for two things from the Indie Hackers community:

1. Feedback on the "Tactical" UX: Does it feel intuitive, or is it too niche?

2. Feature Ideas: What else should a "tactical" monitor track? (Currently, it does real-time CPU/Memory telemetry alongside port monitoring).

If you’ve ever been frustrated by zombie processes, I’d love for you to check it out. It’s open-source and currently optimized for macOS.

I'll be hanging out in the comments to answer any questions about the Rust/Tauri implementation!
