About opentrack

Head tracking, without the price tag

opentrack reads where your head is pointing and feeds that motion to your game as a virtual camera, across all six axes - yaw, pitch, roll and three lean directions. It does the job people once needed a dedicated TrackIR rig for, except it is free, open source, and happy to work with a plain webcam, an infrared LED clip, an eye tracker, a joystick, a phone or a home-built Arduino sensor. Once your head pose is captured and smoothed, opentrack hands it off to whatever your sim expects: SimConnect for Microsoft Flight Simulator, the FreeTrack protocol for most combat sims, X-Plane, FlightGear, a virtual joystick, or SteamVR. It runs on Windows, Linux and macOS.

Why this site exists

opentrack.cc is run independently by people who fly sims and got tired of pointing friends at scattered forum threads. The idea is simple: one tidy place to grab the latest build and learn how to set it up properly, with plain-English guides in our Wiki. The file we point you to is the genuine release - nothing is re-packaged, wrapped in an installer of our own, or padded with extras.

The project and how to help

opentrack grew out of the older FaceTrackNoIR project, was rewritten almost from the ground up, and is looked after today by Stanisław Halik together with a crew of contributors. Nearly all of it ships under the permissive ISC license, so you are free to read, build and modify the source. If it saves you money or a headache, the most valuable thank-you is to pitch in: head over to the official opentrack repository on GitHub to star it, file a bug, sharpen the docs, write a new tracker or output module, or sign on as a contributor.

opentrack.cc is an independent website. It is not affiliated with, endorsed by, or operated by the opentrack project or its maintainers, and it links only to the original software from the official releases.
