What is gazectl?

gazectl is a Swift CLI tool for macOS 14+ that turns your webcam into a head tracking system, using Apple's Vision framework for real-time head pose estimation to detect which display you're looking at and switch focus automatically. It solves the annoyance of clicking or alt-tabbing between monitors by calibrating yaw/pitch angles per screen on first run—look at each one, hit Enter, done. Install globally via npm, grant camera and accessibility perms, and run `gazectl` for hands-free display focus.

Why is it gaining traction?

No third-party window managers or hardware needed—just native macOS APIs for cursor moves and clicks, with hysteresis to avoid boundary flicker. Stands out with polished CLI options like `--calibrate`, `--verbose` yaw logging, and npm releases for quick github head tracker tests. Delivers smooth ~30fps head tracking pc webcam performance that feels responsive for everyday multi-monitor workflows.

Who should use this?

macOS developers with 2+ screens who hate manual focus switches during coding/debugging sessions. Sim enthusiasts tweaking head tracking ets2, head tracking ls25, or head tracking mit webcam setups without buying trackers. Remote workers or gamers seeking head tracking software for pc/ps5 display juggling.

Verdict

Try it if you're on macOS with multiple monitors—simple, effective for the niche despite 49 stars and 1.0% credibility score. Docs are crisp, calibration reliable post-setup, but monitor maturity as an early project before production use.
