Free Enterprise Linux for the community, by the community

AlmaLinux OS Kitten is the direct upstream for AlmaLinux OS and is the primary point for the AlmaLinux community to engage and influence the future of AlmaLinux OS. Fixes and features land here first and trickle down into AlmaLinux OS as appropriate. It is the integration and collaboration point for AlmaLinux to its upstreams as well, such as CentOS Stream and Fedora.

Fully supported, always free

AlmaLinux OS Foundation members, sponsors and partners back the AlmaLinux OS with investments and long support commitments to ensure the distribution is free of limitations, fees and charges.

Re-enabling Frame Pointers

Red Hat Enterprise Linux and CentOS Stream disable frame pointers by default, but with AlmaLinux OS Kitten 10, we are re-enabling them. This enables system-wide real-time tracing and profiling for optimizing the performance of any workload running on AlmaLinux.

Security

AlmaLinux OS provides a set of security features: Errata, GPG keys, Mailing Lists, OpenSCAP, OVAL, SBOM, and Secure Boot - read more.

Effortless to switch to

Switching distributions is usually costly and time-consuming, but that's not the case when switching from CentOS and other RHEL® derivatives to AlmaLinux OS. Switching is easy - read how.

The AlmaLinux OS Foundation

The AlmaLinux OS Foundation was established as a 501(c)(6) non-profit to steward ownership and governance of the project. It owns all assets related to AlmaLinux OS. It is governed by a set of Bylaws. The foundation includes over 400 individual members, over 400 Mirror sponsors, and over 25 Corporate sponsors.
