Steam is Valve's gaming platform client for Linux, providing game library management, automatic updates, social features, and the Steam Workshop for community content. Games and applications are identified by app IDs, which can be used with steam:// URLs for direct launching, installation, and file verification.
Big Picture mode provides a controller-friendly, full-screen interface designed for TVs and the Steam Deck. On Linux, Steam includes Proton, a Wine-based compatibility layer that enables running many Windows games natively. Offline mode allows playing downloaded games without an internet connection.
