AlmaLinux

Launched with the code-name Project Lenix, AlmaLinux OS is an open-source, community-driven project that intends to fill the gap left by the demise of the CentOS stable release. AlmaLinux OS is a 1:1 binary compatible fork of RHEL® 8 and it is built by the creators of the established CloudLinux OS.

As a standalone, completely free OS, AlmaLinux OS enjoys $1M in annual sponsorship from CloudLinux Inc. We will support future RHEL® releases by updating AlmaLinux OS. Ongoing development efforts are governed by the members of the community.

The AlmaLinux OS Foundation is a 501(c)(6) non-profit created for the benefit of the AlmaLinux OS community.
