Debian vs CentOS Stream
Two server systems from opposite traditions: Debian builds its own archive and releases point versions, while CentOS Stream runs ahead of the Red Hat line and lets changes arrive continuously. Both record kernel 6.12 in their newest entries, which makes the packaging and the release flow the deciding factors.

What differs
Base & packages
Debian 13.6 records a full snapshot — GCC 14.2, glibc 2.41, LibreOffice 25.2.3, PostgreSQL 17, PHP 8.4, Python 3.13, OpenSSH 10.0p1, Nginx 1.26, Samba 4.22 — on APT with DEB packages. CentOS Stream has no package snapshot in the dataset at all, so its compiler and library versions are not quoted here; packaging is DNF with RPM.
Desktop & display
GNOME on both, with Wayland recorded as the default. Debian's snapshot names GNOME 48; CentOS Stream records GNOME without a version. Debian also lists an X.Org Server at 21.1.16, while Stream's entry carries no X.Org figure.
Release model
This is the central difference. Stream 10 is dated 19 September 2026 with kernel 6.12, and within a major version changes arrive continuously as the enterprise line is prepared. Debian 13.6 is a point release from 9 August 2025, also on kernel 6.12, with 10.7 from 3 February 2021 kept alongside it.
Hardware requirements
Debian states 2 GB of memory and a 3,628 MB image. CentOS Stream records no minimum RAM and a 906 MB image, so a figure for memory cannot be given for it here.
Init & immutability
systemd on both, recorded as 257 for Debian while Stream's entry names systemd without a version, and neither is immutable. Both install a writable root; Stream's image is smaller because it ships without a desktop payload.
Verdict
Choose Debian if you want a tested package set with named versions, a 2 GB memory floor, and a release line that stays stable for years. Choose CentOS Stream if you are building or testing against the Red Hat enterprise platform and need to see changes before they ship. Debian is the safer base for a machine you will not revisit; Stream is the right base for code that must track the enterprise line.
FAQ
Do both use the same kernel?
The newest entries for both record kernel 6.12: Stream 10 on 19 September 2026 and Debian 13.6 on 9 August 2025.
Why is there no package list for CentOS Stream?
The dataset has no package snapshot for Stream, so no compiler or library versions are stated. Debian's entry has one, which is why its page can quote GCC 14.2 and glibc 2.41.
