Feature comparison
| Feature | AppImage | Flatpak bundle |
|---|---|---|
| Distribution | Single .AppImage file | Flathub repository |
| Install required | No — just chmod +x | Yes — flatpak install |
| Sandboxing | Optional (firejail) | Built-in (bubblewrap) |
| Updates | Manual or AppImageUpdate | Automatic via flatpak update |
| Disk usage | Self-contained | Shared runtimes |
| Offline use | Trivial | Cache the runtime first |
About AppImage
An AppImage is a single-file Linux application: an ELF runtime stub concatenated with a SquashFS image of the app and its libraries. Users chmod +x the file and double-click — no install, no root, no package manager. Updates are delta-based via zsync.

About Flatpak bundle
Flatpak is a Linux app distribution system based on OSTree, a Git-like content-addressed object store. .flatpak bundles are single-file exports of an OSTree commit and are typically distributed via Flathub and installed into per-user sandboxes with portal-mediated access to host resources.
