OBS Studio

OBS Studio is a powerful, free alternative to paid screen recording tools. It supports multiple scenes, source composition, and high-quality recording settings. The open-source project runs on Windows, macOS, and Linux, backed by an active community of educators and creators.

It works for instructors who want advanced features without cost. The learning curve is steeper than browser-based tools, but the flexibility is worth it. You can save recordings locally or stream live to multiple platforms simultaneously.
