Steam is a video game digital distribution service by Valve. It was launched as a standalone software client in September 2003 as a way for Valve to provide automatic updates for their games, and expanded to include games from third-party publishers. Steam has also expanded into an online web-based and mobile digital storefront. Steam offers digital rights management (DRM), server hosting, video streaming, and social networking services. It also provides the user with installation and automatic updating of games, and community features such as friends lists and groups, cloud storage, and in-game voice and chat functionality.

The Steam Controller is a game controller developed by Valve for use with personal computers running Steam on Windows, macOS, Linux, smartphones or SteamOS. The controller was designed not only for games developed for controller users, but also for games traditionally played with keyboard and mouse controls so that they can be played through the controller. It was released in November 2015 to support Valve's Steam Machine and discontinued in November 2019.

Due Process is an online multiplayer tactical first-person shooter video game developed by American studio Giant Enemy Crab, and published by Annapurna Interactive released into early access on November 4, 2020. The game's core revolves around teamwork and communication, allowing players to draw a "playbook" during the planning phase onto the hand-curated, procedurally generated maps. The visuals are inspired by '90s arcade light gun games, such as Time Crisis, and it is set in a cyberpunk dystopia.

Steam Link is a hardware and software solution made by Valve Corporation for streaming Steam content from a personal computer or Steam Machine wirelessly to a mobile device or other monitor. Steam Link was originally released as a hardware device alongside the debut of Steam Machines in November 2015. Valve discontinued the Steam Link hardware device in November 2018, in favor of supporting its software-based Steam Link application for mobile devices and smart televisions, as well as providing Steam Link as a software package for the Raspberry Pi microcomputer.

Steam Machine was a series of prebuilt small form factor gaming PCs designed to operate Valve's SteamOS to provide a video game console-like experience. Several computer vendors were engaged with Valve to develop their own versions of Steam Machines for retail, offering additional options atop Valve's requirements such as dual-booting options with Microsoft Windows and the ability to upgrade the computer.

SteamOS is the primary operating system for the Steam Machine gaming platform and Steam Deck hybrid video game console by Valve.

Steam Trading Cards are a digital commodity issued by Valve for use on its digital distribution platform, Steam. Steam Trading Cards are a non-physical analogue of conventional trading cards, which are periodically granted to Steam users for playing games, fulfilling tasks, or by random chance. Cards can be "crafted" to acquire Steam-centric awards such as emoticons or profile backgrounds, traded to other Steam users, or sold through the Steam Community Market for store credit.
