If you want to delete the app, you just delete the file. - There is no central "App Store" to -weight: 500;">update them. If a new version comes out, you have to go to the website and download the new file manually. - It doesn't automatically add a shortcut to your desktop menu (unless you -weight: 500;">install a third-party tool like AppImageLauncher). - It handles background services and CLI tools very well. If you need to -weight: 500;">install a database or a server utility, Snap is actually pretty great. - Auto-updates are forced in the background, so you are always on the latest version. - Proprietary Backend: The client is open source, but the server that hosts the Snaps is closed source and controlled 100% by Canonical. The Linux community generally hates this. - Clutter: Snaps mount themselves as virtual hard drives. If you type lsblk in your terminal, you will see a massive, ugly list of "loop devices" clogging up your screen. - Performance: Historically, Snaps have been very slow to -weight: 500;">start up. They have improved recently, but they still feel heavier than the alternatives. - Decentralized: Flathub is the main store, but anyone can host their own Flatpak repository. It is truly open source. - Sandboxing: This is the killer feature. Flatpak isolates apps from your main system. An app cannot read your personal files or access your webcam unless you give it permission. - Flatseal: There is a fantastic GUI app called Flatseal that lets you toggle permissions (like Network, Filesystem, Microphone) for every Flatpak app with simple switches. - Because apps are sandboxed, sometimes they struggle to integrate with system themes or custom cursors. - File sizes can be large at first, because it has to download shared "runtimes" (like the GNOME or KDE base files). However, once you have the runtimes, future apps -weight: 500;">install very fast. - Use Flatpak as your default. If a GUI app like Discord, Spotify, or VSCode is available on Flathub, use the Flatpak version. It is secure, updates easily, and respects your system. - Use AppImage for quick tests. If I just need to use a tool once (like a crypto wallet or a specialized video editor) and don't want to -weight: 500;">install it permanently, I grab the AppImage. - Avoid Snap unless absolutely necessary. Unless I am setting up an Ubuntu server and need a specific CLI tool that is only packaged as a Snap, I -weight: 500;">remove snapd from my system entirely.
