Valve Steam Deck

The Steam Deck is a portable handheld gaming computer developed and marketed by Valve Corporation. Launched in February 2022, it represents a significant milestone in mobile PC gaming, designed to play a user's entire Steam library on the go. The device runs on SteamOS, a custom Linux-based operating system that utilizes the Proton compatibility layer to run Windows games seamlessly.

While the brand is rooted in the United States, the physical manufacturing of the Steam Deck primarily takes place in China. This follows common industry practices for high-tech electronics, leveraging established supply chains and specialized facilities for assembly. Valve manages the hardware development in-house, moving away from previous strategies of relying on third-party manufacturers.

Ownership of the Steam Deck brand belongs entirely to Valve Corporation, a private American company led by co-founder Gabe Newell. Valve is best known for creating iconic game franchises like Half-Life and Counter-Strike, as well as operating Steam, the world's largest digital distribution platform for PC gaming. The company remains independent, with no external parent corporation.
