OBS Studio

OBS Studio (Open Broadcaster Software) is free, open-source software for screen recording and live streaming, widely used by streamers on Twitch and YouTube as well as anyone recording tutorials, gameplay, or presentations. Its plugin API lets developers extend functionality with native plugins for performance-critical integrations or scripts written in Lua or Python for lighter customization.

At its core, OBS offers high-performance real-time video and audio capturing and mixing, letting you build scenes from multiple sources at once - window captures, static images, text overlays, browser sources, webcams, and capture cards can all be combined into a single composed output.

You can set up an unlimited number of scenes and switch between them using custom transitions, including your own stinger video clips for a more polished on-stream look. Hotkeys can be assigned to nearly any action: switching scenes, starting or stopping a recording or stream, muting a specific audio source, or enabling push-to-talk - all of which make live production manageable without a dedicated production team.
