Xenmaster's 2026 Distro Hopper Guide

I have noticed in general that the recommendation list for alternatives on this site is broken when it comes to Linux Distros. Often times when looking for a server distro or gaming distros, I will get generic recommendations for any Linux distribution and I will have to guess if the use-case is right. This list seeks to provide true alternatives based on use-cases for the most popular Linux and BSD distributions out there! Note this is a 2026 update to my original list posted several years ago. https://alternativeto.net/lists/23956/xenmaster-s-linux-distro-master-list/ Rather than re-write history, I'm adding a new post with the below link to my original. A lot has changed in the OS world so adding some details regarding what I use and how. Unlike my old list, this one will include both Linux and BSD related systems, similar in their unix-like behavior, but each with different utilities and mechanisms for performing operations. Note that as of the posting of this list, only OpenBSD supports Full Disk Encryption on installation without manual configuration steps, a major drawback if this is a critical component to your use as a desktop setup.

What is secureblue?

secureblue is a security-focused, open-source operating system that ships as rpm-ostree container images derived from Fedora Atomic/CoreOS. It emphasizes proactive hardening—such as removing SUID binaries, enabling hardened_malloc, and disabling unprivileged user namespaces—while retaining Fedora’s default SELinux and user-friendly experience. With features like Network Time Security (NTS) via chrony, DNSSEC + DNS-over-TLS, robust firewall defaults, and optional LUKS TPM2/FIDO2 integration, secureblue aims to deliver a safer Linux environment without sacrificing everyday usability.
