ShareX is not available for Linux but there are plenty of alternatives that runs on Linux with similar functionality. The best Linux alternative is Flameshot, which is both free and Open Source. If that doesn't suit you, our users have ranked more than 100 alternatives to ShareX and many of them are available for Linux so hopefully you can find a suitable replacement. Other interesting Linux alternatives to ShareX are Ksnip, SimpleScreenRecorder, Spectacle and VokoscreenNG.

In my experience, Flameshot has worked far quicker than ShareX. While ShareX does have more features, Flameshot works well as an alternative if you only require a good screenshot tool.
