The AppImage is a universal software package format.
The process of packaging the software in AppImage is a storage file provide by the the developer.
This file is a compressed image with all the dependencies and libraries needed to run the desired software. The AppImage doesn’t really install the software just execute it without no extraction and no installation.
The most common features:
- Can run on various different Linux distributions;
- No need of installing and compiling software;
- No need of root permission and the system files are not touched;
- Can be run anywhere including live disks;
- Applications are in read only mode;
- Software are removed just by just deleting the AppImage file;
- Applications packaged in AppImage are not sandboxed by default.
More about this can be read at official webpage.
I tested the Krita Next with this tool.

About the Krita Next this is a daily builds that contain new features, but could be unstable.

[mythcat@desk Downloads]$ ./krita-4.2.0-pre-alpha-95773b5-x86_64.appimage
