Andronix is a platform that allows you to install and run a full fledged Linux distro on your Android device (smartphone, tablet, or Chromebook). You can install Ubuntu, Debian, Manjaro, Fedora, Kali, Void, Alpine, and Arch Linux. You can try out desktop environment like LXDEm LXQT, and XFCE. This repo contains backend which is under FLOSS.

Repo github.com/AndronixApp
Project andronix.app/

It is not clear (at least for me) if andronix is also open sourced.
