What are the best CentOS alternatives?

Since the IBM-owned company decided to restrict the free use of Red Hat Enterprise Linux, a divide has been growing among users. The main question is whether to migrate to commercial Linux providers or open-source, non-commercial community-developed enterprise operating systems.

In this complex landscape of imminent migration, some top names stand out as CentOS’s top alternatives: Red Hat Enterprise Linux, Oracle Linux, Rocky Linux, AlmaLinux and Fedora.

Red Hat Enterprise Linux: Best for large enterprises

The first name that emerges as an alternative to CentOS is naturally Red Hat Enterprise Linux, as it’s the open-source operating system on which CentOS is based. Therefore, many users think that going directly to the source is naturally a good idea, and they’re not wrong.

RHEL has gained its reputation among big enterprises for providing a modern, security-oriented OS. Companies with advanced digital resources, technology stacks and workloads use the OS to scale and perform on-premises, on virtual machines or containers and in the cloud. The OS is certified on hundreds of clouds and with thousands of hardware and software vendors.

Oracle Linux is another solid alternative for those looking to migrate from CentOS for several reasons. First of all, Oracle Linux is 100% Red Hat Enterprise Linux compatible. It can handle a wide variety of workloads, heavy-duty databases, application servers and DevOps. Additionally, users can migrate from CentOS to Oracle Linux seamlessly using built-in migration features. And, they will benefit from several features that are not available in CentOS.

Fully compatible with RHEL, Oracle offers a choice of two kernels: the Unbreakable Enterprise Kernel for Oracle Linux or the Red Hat Compatible Kernel.

  • The Unbreakable Enterprise Kernel provides the latest open source innovations, key optimizations and security with a focus on performance, stability and minimal backports by tracking the mainline source code as closely as is practical. It is a Linux kernel built by Oracle and supported through Oracle Linux support. UEK is designed for maximum performance and stability and drives Oracle Cloud and Oracle Engineered Systems, such as Oracle Exadata Database Machine. UEK is well-tested and used to run Oracle’s Engineered Systems, Oracle Cloud Infrastructure and large enterprise deployments for Oracle customers.
  • The Red Hat Compatible Kernel is for Oracle Linux, and it is compatible with the Red Hat Enterprise Linux kernel; this means that software that is compiled for RHEL will also run on Oracle Linux with RHCK.

Oracle Linux is a good choice for businesses and organizations that need a stable, reliable and secure operating system. It is also popular among IT and software companies because of the features listed below.

AlmaLinux is another forked version of CentOS, owned and governed by a community of developers. Like RockyLinux, the OS began development when CentOS announced it would no longer offer support or release new versions.

The community behind AlmaLinux assures that the OS will always be free for enterprises, and that they are focused on long-term stability and a robust production-grade platform. The company adopted a Fedora-like distribution for anyone who does not want to pay for RHEL licenses. AlmaLinux is supported by CloudLinux Inc. and other sponsors.


  • Migration: AlmaLinux does not have built-in automated step-by-step technology that guides users through migration. AlmaLinux does offer guides, but only those with advanced skills will be able to follow them (Figure D).
  • Production-ready: AlmaLinux OS is an enterprise-grade server OS. It is a stable Linux distribution and offers regular releases and support. It is designed for critical workloads. The organization provides official images for cloud providers including AWS, generic clouds, Google Cloud, Microsoft Azure, OpenNebula and Oracle Cloud Infrastructure.

Fedora is an innovative platform loved by programmers because it provides cutting-edge technology, is reliable and stable, and is a free and open-source OS packed with features.

Fedora is also a community-supported Linux distribution developed by Red Hat. In concept, it compares more to CentOS Stream than to CentOS because it offers rolling release distribution, giving users access to the latest technology. New features and updates are released on a continuous basis. The new features in Fedora are available before they are released in Red Hat Enterprise Linux. Fedora also invests heavily in graphic user experience and provides easy-to-use, high-quality graphics through modern desktops (Figure E).

Is CentOS still relevant?

CentOS is still a relevant Linux distribution despite it being on the countdown for its end of life. You could think of CentOS as a very good car that the manufacturer is no longer producing. While you can still use the car and it works perfectly, you will not receive upgrades, new versions or support. In the near future, it is expected to become outdated.

Will there be a CentOS 9?

No, there will not be a CentOS 9. Red Hat announced it would no longer support CentOS as a downstream distribution of RHEL. This means there will be no new versions of CentOS released after CentOS 8.

However, led by a large community and supported by commercial partners, forks of CentOS such as Rocky Linus and AlmaLinux are being developed. These forks are designed to be 100% compatible with CentOS, so they can be used as a drop-in replacement for CentOS.

Is CentOS good in 2023?

While CentOS in 2023 is still a good option, developers and businesses are already looking into migrating to other alternatives.

Having said that, CentOS is still stable, reliable and compatible with a wide range of software in 2023. It is also still free and open-source, and has the support of an active community of users and developers. However, due to the end of CentOS as we know it, it may not be the best choice for everyone in 2023 and beyond.

What is the future of CentOS?

While the future of CentOS is uncertain, the most likely scenario is that one of the organizations developing forks of it becomes the go-to OS for this community by mid-2024 when it reaches its end of life.

On the other side, from Red Hat’s perspective, the future of CentOS is CentOS Stream, which is a new Linux distribution developed by Red Hat, an IBM-owned company. But CentOS Stream is not a replacement for CentOS — it is a different distribution with a completely different focus. It aims to be at the forefront of development by offering users rolling release distribution to test new features and updates before they are released in RHEL. In this way, it is similar to Fedora; also, both are developed by Red Hat, and both offer rolling releases.

How do I choose the best CentOS alternative for my business?

There is no easy answer to this question. When choosing an alternative for CentOS, business leaders should consult with their developers to learn which OS they feel more comfortable with because they will be the ones operating the system.

On the other hand, budget may be a deciding factor, especially for small companies. Additionally, among CentOS users and developers, there is a strong sense of community, support and respect for free open-source projects. Therefore, even if a company has the budget to buy the most expensive licenses, developers may feel more confident and comfortable working with open-source, free technology.

Some users may see the end of life of CentOS as an opportunity to migrate to another OS such as Oracle Linux or Red Hat Enterprise Linux. These more conservative choices offer features that CentOS does not offer.

In the end, the OS you choose must align with your business needs and goals, be flexible, reliable and secure, and provide excellent migration and support. Scaling, automation, upgrades and compliance are also key components to analyze.


CentOS has provided vital services for organizations, companies and developers for many years. While the OS faces the inevitable end of its glory days, there are still solid new and established Linux OS distributions in the market.

From CentOS-inspired community OSs like Rocky Linux or AlmaLinux, to a cutting-edge OS like Fedora, or the big names of Oracle and Red Hat Linux, the options are as diverse as they are rich. It will be up to every business to decide which Linux distribution fits their operational needs.


To write our review and evaluate CentOS competitors and alternatives, we examined sites that compile aggregate data based on verified user reviews. We also reviewed demos on vendor sites, test-drove the software when possible and scoured through the official sites of all OS providers’ features in this report to evaluate their software, customer service, user-friendliness, price, scalability and more.
