XAR is a toolchain for packaging many files into a single self-contained executable archive based on a read-only SquashFS image. It is commonly used to distribute Python applications with all their source, native libraries, and data as one fast-starting, highly compressed file.

Use cases

package a python application into a single executable file
replace virtualenv or pex with a faster self-contained archive
compress and distribute many files as one mountable image
ship python code with native shared libraries and data files
reduce on-disk size and random disk io for deployed applications

When to avoid

you cannot install kernel drivers or setuid helpers on target systems
you need a pure-python, no-root packaging solution
you target windows or platforms without squashfs support
