ALT Linux, developed and maintained by the Russian company Basalt SPO (formerly ALT Linux Team), has been an active and self-sufficient Linux project since 2001. Unlike many distributions that layer atop Debian or Fedora, ALT charts its own course using the Sisyphus rolling repository and a custom fork of Debian's APT tooling adapted for RPM packages — a system commonly called APT-RPM. This unique approach gives ALT exceptional flexibility and independence while demanding a slightly steeper learning curve.
A Diverse Lineup of Editions
ALT offers a wide range of purpose-built editions including ALT Workstation, ALT Server, ALT Education, ALT KWorkstation (KDE-focused), ALT GNOME, and Simply Linux — a beginner-friendly variant. This variety makes ALT suitable for everything from individual desktops to multi-server enterprise deployments. Each edition ships with curated software appropriate to its target audience, reducing bloat and keeping the system lean and purposeful.
Package Management with APT-RPM
The APT-RPM system combines the familiarity of apt-get command syntax with the RPM package format. Veteran Fedora or RHEL users will recognize .rpm packages, while those from Debian backgrounds will find the apt-get commands comfortable. The Sisyphus repository is a continuously updated rolling branch with tens of thousands of packages, while the stable p10 branch offers a more conservative update cadence. This dual-track approach allows users to balance stability with access to newer software.
Security and Enterprise Focus
ALT Linux places a strong emphasis on security. It integrates SELinux, Mandatory Access Control (MAC) policies, and has been certified for use in Russian government and enterprise environments. The distribution ships with PAM configurations, network security tools, and firewall management utilities out of the box. For organizations with compliance requirements, ALT's certifications and hardened defaults offer a compelling advantage over more casual consumer distributions.
Hardware and Architecture Support
One of ALT's standout features is its broad architecture support. Beyond x86_64 and the legacy i586, ALT actively maintains builds for ARM, RISC-V, and other platforms — making it useful for embedded, server, and emerging hardware ecosystems. This positions ALT well for organizations exploring hardware diversification or requiring deployments on non-standard architectures.
Community and Documentation
ALT has a dedicated Russian-speaking community with a wiki, forums, and active mailing lists. English documentation exists but is less comprehensive, which can be a barrier for international users. The project has historically focused on the Russian market, though its technical merits have attracted users globally, particularly those seeking an independent, non-Debian, non-Arch alternative with RPM tooling and strong security features.
Performance and Stability
On supported hardware, ALT runs smoothly. The p10 stable branch is well-tested and appropriate for production workloads. Sisyphus users get a more bleeding-edge experience, though the rolling nature requires attentiveness during upgrades. ALT Workstation with KDE Plasma is responsive even on modest hardware, and the server edition is lightweight enough to deploy on virtual machines with minimal resources.
