AppImages

But what if you still don't see what you're looking for. In some cases then, you might consider AppImages.

Like Flatpaks these are distro agnostic meaning they work on any version of Linux. Like Windows exe's they simply require a download and double-click to install and use. They were used frequently before the introduction of Flatpaks and serve a similar purpose but ultimately have mostly been replaced by them. If you can't find something it's worth checking to see if an AppImage exists of it.
