This purchase does not include a Steam key. The offline version does not support the Steam Workshop and not all mods are available outside the Steam Workshop. You can buy Software Inc. on Steam at the bottom of the page.

The purchase includes:

  • Immediate access to the current version
  • All future updates
  • The final release
  • Windows, Mac and Linux builds
  • No ads and no In-app purchases, ever

Note that the difference between the Steam release and the version you can buy on this site, is that the Steam version will require that Steam is running when you launch Software Inc. The version sold on this site will not have any Steam synchronization. Buying the game on Steam does not include the version sold on this site.

If you have any problems please contact me at SoftwareInc at
