We are now in beta 🎉

What is AstrOS?
Section titled “What is AstrOS?”It is an immutable, secure-by-default Linux distribution based on Arch Linux and the COSMIC desktop environment. It uses similar tooling as GNOME OS and KDE Linux.
What makes AstrOS special is its immutable base, which is shipped as a hashed and signed /usr image that is booted by signed uki images. This combination protects your system from outside modification.
AstrOS base can be extended with currently four extensions (or your own). Including a steam gaming extension with the steamos gamescope session.
