Flatpak

intro paragraph

To install Flatpak, go the Quick Setup page on Flatpak.org, pick your distro, and follow the instructions. You can skip all the pointless GUI plugins for GNOME/Plasma/etc as they will only add bloat. You can very quickly manage all of your Flatpak apps with just a handful of terminal commands, which we will explain next.

Snap is the Ubuntu equivalent of Flatpak, packaged with Ubuntu straight from Canonical. It is less open of a platform (the community is limited to Ubuntu users, and Canonical controls the repositories) and startup times are usually slower than Flatpaks as well. It's Foss has a writeup explaining these differences in detail.

Because of those drawbacks, many Ubuntu desktop users prefer to remove Snap entirely, and replace it with Flatpak. We recommend this as well, as it will allow your Ubuntu system access to a wider library of Linux applications than you would normally get with Snap. This is done with the Github package popey/unsnap. There is a guide about how to do this at FOSSlife that explains this further.
