Stripchat Recorder

Open-source browser app to record your screen, tab, window, and/or webcam locally—with PiP, teleprompter, and optional in-browser MP4 conversion—no install required.

Loom is software that lets you instantly record your screen. Once the recording is complete, it's automatically uploaded to your user account, where you can share it via a link so others can watch it immediately. Of course, if you don't like the video, you can delete it before anyone else sees it.
