OBS Studio is the industry standard for open-source screen recording and live streaming. It supports scene composition with multiple sources, real-time audio/video mixing, custom transitions, and streaming to platforms like Twitch and YouTube simultaneously.
It is completely free with no paid tier or feature restrictions. The plugin ecosystem extends functionality enormously, though the learning curve is steeper than simpler recording tools. Available on Windows, macOS, and Linux.
