CentOS Stream is a rolling-preview Linux distribution that acts as the upstream development branch for Red Hat Enterprise Linux (RHEL). It bridges the gap between the rapid innovation of Fedora and the long-term stability of RHEL. Unlike the legacy CentOS, which tracked RHEL releases after they were published, Stream provides a preview of what the next minor version of RHEL will become.
The distribution operates on a continuous delivery model. This allows hardware and software vendors to test their products against upcoming RHEL features and APIs. Updates flow into the CentOS Stream repositories as soon as they are staged for the next RHEL minor release, ensuring that the platform reflects the current state of enterprise Linux development in real-time.
How it works
CentOS Stream is used in environments that require RHEL compatibility but benefit from faster access to updates. Typical scenarios include:
- Building and testing applications for future RHEL environments;
- Integrating third-party hardware drivers and kernel modules;
- Running workloads that need the latest security patches without waiting for a full RHEL point release.
Technical fact: Since the shift to CentOS Stream, the distribution has become the primary source for RHEL 9 and subsequent versions, effectively making it the public development branch for the world's leading enterprise Linux platform.
