OMOS is proprietary software, but proprietary doesn’t mean paid. The compiled system is free to download and use for almost everyone — a royalty is owed only by large commercial users.

​
What’s free

You can install and use OMOS at no charge, with no per-machine fee and nothing to buy, for:
  • Personal use.
  • Education and academic use.
  • Non-profit use.
  • Commercial use by any individual or company with under $1,000,000 in annual revenue.
That covers essentially everyone building, learning, tinkering, or running a smaller business.

​
When a royalty applies

If your annual revenue is **1,000,000ormore∗∗andyou′reusingOMOScommercially,thatuseneedsapaidcommerciallicense:a∗∗51,000,000 or more** and you're using OMOS commercially, that use needs a paid commercial license: a **5% royalty** — applied only to the portion of the relevant revenue *above* 1,000,000, not the whole amount. Personal, education and non-profit use stays free no matter your revenue. It is not an auto-renewing subscription. For a commercial license at scale, get in touch at burakov.work@gmail.com.
