Please first refer to for new user guide, frequent answers, specific tracker/filter documentation. See also the gameplay video with opentrack set up.

Looking for railway planning software?

Railway planning software HERE had the name opentrack first. Apologies for the long-standing naming conflict.


opentrack is an application dedicated to tracking user's head movements and relaying the information to games and flight simulation software. The octopus will rotate as you move your head.

opentrack allows for output shaping, filtering, and operating with many input and output devices and protocols; the codebase runs Microsoft Windows, Apple OSX (currently unmaintained), and GNU/Linux.

Don't be afraid to submit an issue/feature request if you have any problems! We're a friendly bunch.
