Python ecosystem

If you feel like running arbitrary code downloaded over the internet (pypi doesn't support gpg signatures anymore), mat2 is available on pypi, and can be installed like this:

pip3 install mat2


Optional dependencies

When bubblewrap is installed, mat2 uses it to sandbox any external processes it invokes.

Arch Linux

Thanks to Francois_B, there is an package available on Arch linux's AUR.


There is a package available in Debian.


Thanks to atenart, there is a package available on Fedora's copr.

We use copr (cool other packages repo) as the Mat2 Nautilus plugin depends on python3-nautilus, which isn't available yet in Fedora (but is distributed through this copr).

First you need to enable Mat2's copr:

dnf -y copr enable atenart/mat2

Then you can install both the Mat2 command and Nautilus extension:

dnf -y install mat2 mat2-nautilus


mat2 is available in the torbrowser overlay.
