Red Hat Enterprise Linux: When certification, an audit trail or a vendor contract requires the certified product rather than a compatible one
AlmaLinux
RHEL-compatible Linux from a non-profit foundation that chose interface compatibility over an exact rebuild
As of 31 August 2026, AlmaLinux is free to use. The other CentOS replacement, governed by a foundation with an elected board. Softwr lists it under Operating Systems. AlmaLinux is made by AlmaLinux OS Foundation, available on Web.
Overview
What AlmaLinux does
AlmaLinux is a free enterprise Linux distribution created in 2021 by CloudLinux after Red Hat discontinued CentOS Linux, then handed to the AlmaLinux OS Foundation, a non-profit with a community-elected board. Major releases track RHEL and are supported for about ten years, with AlmaLinux 9 maintained to 2032 and AlmaLinux 10 to 2035. When Red Hat restricted RHEL source access in June 2023, AlmaLinux made the opposite choice to Rocky Linux. It publicly abandoned one-to-one rebuilding and now targets application binary interface compatibility, building from CentOS Stream and other available sources. The practical consequences are visible in the shipped product. AlmaLinux has issued backported fixes for security issues before the corresponding RHEL update appeared. It restores hardware support that Red Hat removed, and AlmaLinux 10 ships a build for the older x86-64-v2 instruction set alongside the v3 build, so it installs on pre-2015 servers that RHEL 10 refuses to run on. It also enables frame pointers for profiling. Anything compiled for RHEL should still run; anything that inspects exact package versions may notice the difference. The buyer is an organisation that wants a RHEL-shaped platform without a subscription and values governance and hardware reach over identity with Red Hat's output. The trade-off is precisely that divergence: if a vendor certification, an internal validation suite or a regulator expects the same code Red Hat shipped, running patches Red Hat has not published is a question you will have to answer. The foundation is also still funded largely by CloudLinux and cloud sponsors, so independence is structural rather than financial.
What people use it for
- Keeping pre-2015 x86 servers in production past the point RHEL 10 will install on them
- Hosting providers and control panel users, where CloudLinux lineage means cPanel and similar stacks are tested
- Teams that want faster security patching than a strict downstream rebuild can offer
- Migrating CentOS 7 estates in place using ELevate rather than rebuilding every machine

The honest half
Where it falls short
Concrete and checkable, so you can decide whether any of them matter to you. This is the half of a review a vendor will not write about AlmaLinux.
- It is deliberately not identical to RHEL, so any validation, certification or compliance process that assumes matching package contents needs re-examining before you standardise on it.
- Shipping security fixes ahead of Red Hat means running code Red Hat has not published, which some regulated buyers treat as unvalidated rather than as an advantage.
- No ISV support contract names AlmaLinux, so escalations with database and application vendors can stop at the operating system question.
- Funding is concentrated in CloudLinux and a few cloud sponsors, so the elected board governs a project whose engineering capacity still depends heavily on one company.
- Divergence from RHEL accumulates across a ten-year lifecycle, and the further into a release you are, the harder it becomes to argue that a RHEL test result predicts AlmaLinux behaviour.

x86-64-v2 build
AlmaLinux 10 supports older CPUs that RHEL 10 dropped, extending the life of existing servers
ELevate
In-place major version upgrades, including CentOS 7 to 8, and the tool other rebuilds rely on
Restored hardware support
Drivers and devices removed from recent RHEL releases are added back where practical
Elected governance
A 501(c)(6) foundation with a board elected by contributors rather than a single sponsor
Frame pointers enabled
Profiling and stack sampling work on shipped binaries without rebuilding them
Answered, with sources
Questions people ask
Each answer names the page it came from, so you can check it rather than take our word for it.
What does ABI compatible mean in practice?
Binaries and kernel modules built for RHEL load and run. Package versions, patch sets and hardware support may differ. If your software only calls interfaces, you will notice nothing; if it inspects versions, you might.
Which should I choose between AlmaLinux and Rocky Linux?
Rocky if a third party certifies against exact RHEL package versions or you want the closest possible copy. AlmaLinux if you need older CPU support, faster patches, or a foundation with an elected board.
Is there paid support?
Yes, but not from the foundation. CloudLinux and TuxCare sell support and extended lifecycle services, quoted rather than published.
Can I convert an existing RHEL or CentOS machine?
Yes. almalinux-deploy converts same-version RHEL and CentOS installs, and ELevate handles major version jumps, including from CentOS 7.
