Operating Systems

Pick your OS.
We handle the rest.

Deploy any of our supported operating systems on your Cloud Cube — we manage patches, updates, and security regardless of your choice.

Free operating systems

Deploy any of these at no additional charge — included with every Cloud Cube plan.

Free

AlmaLinux

The drop-in RHEL-compatible replacement. Binary-compatible with Red Hat Enterprise Linux — the go-to choice for cPanel, DirectAdmin, and production workloads that need enterprise-grade stability.

Best for: cPanel, DirectAdmin, production workloads, RHEL migrations
  • 1:1 binary compatible with RHEL — software runs without modification
  • Long-term support with community-backed security patches
  • Required OS for cPanel/WHM — only free OS cPanel supports
  • SELinux support, enterprise package ecosystem via DNF
Free

Debian

The universal operating system. Battle-tested, rock-solid, and the foundation that Ubuntu is built on. Favored by developers who want a lean, predictable base without any extras.

Best for: custom stacks, developers, lean servers, Docker hosts
  • Extremely stable — changes only when they're ready
  • Minimal footprint — install only what you need
  • Massive package repository via apt
  • Strong community and over 30 years of production use
Free LTS

Ubuntu LTS

The most widely used Linux server distribution in the world. Huge ecosystem, excellent documentation, and 5-year LTS support make it the default choice for web apps, Node.js, Python, and modern stacks.

Best for: RemarkablePanel, web apps, Node.js, Python, Docker
  • Required OS for RemarkablePanel — our hosted control panel
  • 5-year LTS support cycle with optional 10-year extended maintenance
  • Largest community — most tutorials, guides, and documentation
  • First-class support from virtually every software vendor

Commercial operating systems

Available as a licensed add-on to any Cloud Cube. License fees are billed separately and are not discounted.

Licensed

CloudLinux

The hosting industry's OS of choice. Built on top of AlmaLinux/RHEL with LVE technology that isolates each account — preventing one user from consuming all server resources.

Best for: shared hosting, resellers, multi-tenant cPanel servers
  • LVE isolates CPU, RAM, and I/O per account
  • CageFS — each user sees only their own files
  • MySQL Governor — per-user database limits
  • HardenedPHP — run multiple PHP versions securely
Licensed

Windows Server 2025

Microsoft's latest server platform with support for .NET, MSSQL, IIS, and the full Windows ecosystem. The right choice when Linux isn't an option.

Best for: .NET apps, MSSQL, IIS, Active Directory, Windows-native software
  • Full RDP access and Remote Desktop management
  • IIS web server and ASP.NET support
  • MSSQL Server compatible
  • Only OS that supports Plesk on Windows
