A Screen Studio alternative for Mac, and others
People arrive here from a few different searches: an alternative to Screen Studio because they want a one-time licence or local-only recording, an alternative to Loom because the screen cannot be uploaded, a replacement for OBS Studio because live streaming tools are more than a tutorial needs. Each product above has its own comparison, with the other tool's own documentation cited and a clear verdict on who should choose which. The Screen Studio comparison is the closest for anyone who wants automatic zoom, and apps like OBS Studio for Mac lists the alternatives for people leaving it.
How to read the comparisons
Each comparison states who should choose the other product as plainly as who should choose ReScreen, and every comparison article cites the other vendor's own documentation, with the date it was checked implied by the article's own date.
