Debian is the founding parent of the largest family in the Linux world. Dozens of distributions are built on its foundation, yet each has gone its own way — some toward simplicity, some toward security, some toward gaming. Here's a map of the family so you know who's who.
Ubuntu is the biggest and most influential member of the family. Born in 2004 as a friendlier Debian, today it's the standard for "Linux that just works." Long-Term Support (LTS) releases arrive every two years and receive at least five years of fixes, and with the paid Ubuntu Pro service, support stretches to 12 years. Cloud providers, big companies, and developers all lean on Ubuntu. Its drawback — the weight of GNOME and Snap packages — makes it hungrier than its parent.
From Ubuntu in turn came: Linux Mint — the favorite of Windows switchers, with its familiar menu and Cinnamon desktop; Pop!_OS — focused on gaming and development, with a great out-of-the-box experience for NVIDIA cards; Zorin OS — made to look like Windows or macOS, depending on your taste; elementary OS — with a macOS-flavored interface. All of them inherit Ubuntu's fresher software versions and easy installation.
Not all of Mint is Ubuntu. There's also LMDE (Linux Mint Debian Edition) — the same familiar Mint, but standing directly on Debian with no Ubuntu in between. The team maintains it as an insurance policy: if Ubuntu ever moves in a direction Mint dislikes, they have a foundation ready. LMDE is a great choice for people who want Mint's convenience but prefer clean Debian underneath.
MX Linux is a Debian-based system with Xfce that has topped popularity charts (DistroWatch) for years. It's light, stable, and ships with useful maintenance tools others lack. Its parent antiX is even lighter — built precisely for machines the rest of the world forgot. Both offer the option to run without systemd if you prefer the classic way.
Kali Linux is the standard for penetration testing. It packs more than 600 security tools, ready from the first second — made by Offensive Security and used by professionals worldwide. A quick note: installing it doesn't make you a hacker, and writing about it doesn't make the author one either.
Parrot OS is a more balanced option — besides security tools it includes everything needed for everyday use. Tails is a different beast entirely: a live system that boots from USB, routes all traffic through Tor, and leaves traces in memory rather than on disk. It's favored by journalists and activists for whom anonymity is a matter of safety. PureOS is the strictest of all — free software only, privacy first, the official system for Purism devices.
Raspberry Pi OS (formerly Raspbian) is the official system for the most popular mini computer. It's Debian optimized for the Pi's ARM hardware — with the light PIXEL desktop and built-in tools for learning to code. Devuan, meanwhile, is Debian without systemd — created by people who dislike the direction of the modern init system and want the old, predictable SysVinit or OpenRC.
Proxmox VE is a full virtualization and container platform built on Debian — a favorite of system administrators. SparkyLinux, Q4OS, Peppermint OS, and Bodhi are smaller but loyal options for light machines and particular tastes. Deepin attracts attention with one of the most beautiful interfaces in Linux.
All of these systems share one core — the APT package manager and Debian's stability. Choosing between them isn't a choice between fundamentally different technologies, but between different priorities: Ubuntu's ease, Mint's familiarity, MX's lightness, Kali's security. However different they look on the surface, they all speak the same language — the language of Debian.
