portable reproducible environments for Linux applications

What is prenv?

prenv is a tool that allows regular users to deploy applications in a portable and reproducible way.

prenv does not require root privileges to be installed or used. The focus of prenv is to provide a tool that can be used to run applications in a reproducible way, without the need to install dependencies on the host system.
