OBS Studio is free, open-source software for livestreaming and video recording, rather than a game with its own playable world or competitive loop. Its role is to help creators assemble and manage a broadcast or recording: sources can include a game, webcam, images, text, browser windows, and other inputs. Any displayed activity reflects people using the software through Steam, not necessarily people playing one shared game.
The distinctive work happens in arranging those ingredients into scenes and controlling the audio and transitions. Users can switch between scenes, configure per-source audio filters, and use hotkeys for actions such as starting a recording or muting an input. Studio Mode offers a chance to preview and adjust scenes before putting them live, while Multiview provides an overview for monitoring and cueing scenes. These are production controls, not game mechanics, and the software supports both streaming to services such as Twitch and YouTube and saving recordings locally.
The tool itself does not define what its users are playing or recording. Its scenes, mixing, and preview features explain why someone might open it alongside a game, but the count cannot identify which games or streaming destinations are involved.
