OS Reference

Comprehensive reference covering 26 security-focused, privacy, forensics, and general-purpose operating systems across 9 categories — including Kali Linux, Parrot OS, BlackArch, Tails, Qubes OS, and REMnux. Each entry breaks down the OS's architecture, standout tools it ships with, ARM compatibility, and who it's actually built for, so you can pick the right distro for a penetration test, a forensics investigation, or an anonymity-focused workflow instead of guessing from a download page. Compare distros side by side by category or search directly for a specific tool you know you need — the whole reference works offline once the page has loaded.
