OBS Studio is the free, open-source software for live streaming and video recording that powers a huge share of the world’s streamers, podcasters, and video creators.
OBS (Open Broadcaster Software) lets you compose scenes from any combination of sources — game or window capture, webcams, capture cards, images, text, and browser pages — then switch between scenes live while streaming to Twitch, YouTube, Facebook, or any RTMP destination, or recording locally. A built-in audio mixer gives every source its own filters, including noise gate, noise suppression, and compressor, plus VST plugin support. Studio Mode previews edits before they go live, Multiview monitors up to eight scenes at once, and every action can be bound to hotkeys. Recordings support high-quality local capture with a replay buffer, and a virtual camera output feeds your composed scene into Zoom or Teams. An extensive plugin ecosystem and scripting API (Lua and Python) extend it further, with tools like remote control over WebSocket. OBS runs on Windows, macOS, and Linux and is maintained by a large community. It has also become the foundation that many commercial streaming apps are built on.
OBS Studio is completely free and open source (GPL). There are no watermarks, no feature locks, and no subscriptions — download it from obsproject.com.
OBS Studio is for streamers, podcasters, educators, and anyone who needs professional control over live broadcasts and recordings without paying for studio software.
