Monosnap
Free screenshots, annotation and recording with cloud sharing
About Monosnap
Monosnap is the closest free match to CleanShot X's full workflow: capture, annotate, record video or GIF, then upload and share a link — the loop support teams and QA testers live in all day.
It has been around for a decade, which shows in both maturity and a slightly dated interface, and it is a regular in CleanShot-alternative roundups as the no-cost option that does not cut features.
The free tier covers personal use with cloud upload; paid plans add storage and team management.
