OBS Studio is used for live streaming and screen recording. It lets you combine sources like your screen, webcam, microphone, images, text, and overlays into a polished broadcast or video.

What people use it for

  • Streaming gameplay to platforms like Twitch or YouTube.
  • Recording tutorials, presentations, and demos.
  • Making webinars and online classes with multiple audio/video sources.
  • Creating custom scenes with transitions, overlays, and on-screen text.

Why it’s popular

OBS is free, open-source, and cross-platform , so it works on Windows, macOS, and Linux. It’s also known for giving users a lot of control over scene layout, audio mixing, and capture quality.

Quick example
