Screenie

Screenie is a macOS screen recorder written in Swift that edits the recording for you: automatic click zooms, cursor tracking, speed ramps, and the finished clip copied straight to your clipboard.

Demo videos usually mean recording, then twenty minutes in an editor adding zooms so viewers can follow the cursor. Screenie does that during capture — stop recording and the edited version is already on your clipboard, ready to paste into Slack or a PR.
