Our verdict on Debian

Debian is a free, open-source operating system from the Debian Project for general-purpose servers, personal computers and cloud environments. Systems use the Linux or FreeBSD kernel, include system utilities and access to more than 70,000 packaged software options through APT. Debian 13 “trixie” is the current stable release and supports architectures including amd64, arm64, armhf, ppc64el, riscv64 and s390x. That combination suits teams seeking a broadly compatible foundation for self-hosted and cloud workloads.

There is no license charge for Debian, and the published model is a free plan. APT manages installation, removal and distribution upgrades for Debian packages (.deb), while the repository provides packaged software for common server needs. Deployment can start with installation images for physical computers or live boot media from CD, DVD or USB. For cloud operations, official images are available for OpenStack and local QEMU, with machine images for Amazon EC2 and Microsoft Azure. These options make Debian practical when infrastructure spans on-premises hardware and multiple cloud platforms.

Debian 13 has a five-year lifecycle: three years of full Debian support through August 9, 2028, followed by LTS through June 30, 2030. Support channels center on documentation and community resources, so organizations should plan their own operational processes around those channels. Debian is a strong fit for administrators who value stable releases, security updates, architecture choice and control over package management. Teams wanting built-in AI capabilities, a commercial support tier or broader 32-bit architecture coverage should evaluate alternatives alongside Debian.
