Open Source CleanShot X Alternative
CleanShot X set the bar for Mac capture tooling. The reasons people look for an alternative are usually specific: the licence, the price, or wanting to read the code that handles their screen.
This guide will cover the features worth comparing rather than counting, what open source does and does not guarantee about your data, and how the current Mac capture tools line up.
The side-by-side table is already on the site: how Sealshot compares. Sealshot itself is free, open source, and on GitHub.
The full guide is being written. In the meantime the comparison above covers the same ground.
