Flatpak
Linux system for building, distributing and running sandboxed desktop applications across distributions.
HN commenters like it for running up-to-date desktop apps on stable distros like Debian or Alpine without dependency conflicts123, and for sandboxing that leaves little behind when an app is removed.45 The most common complaint is that sandbox permissions break features like file access, game controllers and theming678, and several users found it buggy or unreliable.910
