Valve has released a first beta of their upcoming SteamOS



We've been hard at work to deliver on our promise of a new kind of living room entertainment environment - one that is accessible, powerful and open.

In making the SteamOS Beta available to you, we're excited to take the next major step towards that goal. But before you dive in, please take a few minutes to understand what SteamOS Beta is and what it is not (yet).

So, what is SteamOS Beta?

SteamOS Beta is an early, first-look public release of our Linux-based operating system. The base system draws from Debian 7, code named Debian Wheezy. Our work builds on top of the solid Debian core and optimizes it for a living room experience. Most of all, it is an open Linux platform that leaves you in full control. You can take charge of your system and install new software or content as you want.

So, what is it not?

As an early release, much is changing, so expect rough edges. In its current state, SteamOS is definitely not a finished product ready for a non-technical user.

Most importantly, it currently only supports a certain set of hardware (you can read more in our FAQ). We are hard at work to expand this list.

That being said, we already use it in our living rooms. We are excited about what it is and what it will become. And the more of you do the same and tell us about your experiences, the quicker those rough edges will be sanded off.

Users should not consider SteamOS as a replacement for their desktop operating system. SteamOS is being designed and optimized for the living room experience.

Is all of SteamOS Beta open source software?

No. SteamOS Beta ships with our Steam Client program, which is proprietary software, in addition to proprietary 3rd party drivers. In the SteamOS Beta standard configuration, the Steam Client program serves as a user interface and provides connectivity to our Steam online services. That being said, you can still access standard Linux desktop.
