snek is a tool for managing portable Python environments. It allows you to create isolated Python environments that can be easily shared and deployed across different systems.
Existing Python packaging is a maze of environment variables and setup scripts. snek moves the complexity from the runtime to the bundle. By using zipimport for source code and a content-addressed cache for native binaries, snek achieves O(1) setup—it runs as fast as a native binary because it IS a native binary.
