Providing an AppImage would have, among others, these advantages:
- Applications packaged as an AppImage can run on many distributions (including Ubuntu, Fedora, openSUSE, CentOS, elementaryOS, Linux Mint, and others)
- One app = one file = super simple for users: just download one AppImage file, make it executable, and run
- No unpacking or installation necessary
- No root needed
- No system libraries changed
- Works out of the box, no installation of runtimes needed
- Optional desktop integration with
appimaged - Optional binary delta updates, e.g., for continuous builds (only download the binary diff) using AppImageUpdate
- Can optionally GPG2-sign your AppImages (inside the file)
- Works on Live ISOs
- Can use the same AppImages when dual-booting multiple distributions
- Can be listed in the AppImageHub central directory of available AppImages
- Can double as a self-extracting compressed archive with the
--appimage-extractparameter - No repositories needed. Suitable/optimized for air-gapped (offline) machines
Here is an overview of projects that are already distributing upstream-provided, official AppImages.
If you have questions, AppImage developers are on #AppImage on irc.freenode.net.
