This page attempts to draw a comparison between Arch Linux and other popular GNU/Linux distributions and UNIX-like operating systems. The summaries that follow are brief descriptions that may help a person decide if Arch Linux will suit their needs. Although reviews and descriptions can be useful, first-hand experience is invariably the best way to compare distributions.
In all of the following, only Arch Linux is compared with other distributions. Community ports that support architectures other than x86_64 can be found listed among the Arch-based distributions.
Source-based distributions are highly portable, giving the advantage of controlling and compiling the entire OS and applications for a particular machine architecture and usage scheme, with the disadvantage of the time-consuming nature of source compilation. The Arch base and all packages are only compiled for the x86_64 architecture.
- CRUX is a lightweight distribution that focuses on the KISS principle. CRUX inspired Judd Vinet to create Arch.
- CRUX uses BSD-style init scripts, whereas Arch uses systemd.
- While Arch uses a rolling release system, CRUX has more or less yearly releases.
- Both ship with ports-like systems, and, like *BSD, both provide a base environment to build upon.
- Arch features pacman, which handles binary system package management and works seamlessly with the Arch Build System. CRUX uses a community contributed system called prt-get, which, in combination with its own ports system, handles dependency resolution, but builds all packages from source (though the CRUX base installation is binary).
- Both Arch and CRUX officially support only the x86_64 architecture.
- Arch features a large array of binary package repositories as well as the Arch User Repository. CRUX provides a more slimmed-down officially supported ports system in addition to a comparatively modest community repository.
- LFS, (or Linux From Scratch) exists simply as documentation. The book instructs the user on obtaining the source code for a minimal base package set for a functional GNU/Linux system, and how to manually compile, patch and configure it from scratch. LFS is as minimal as it gets, and offers an excellent and educational process of building and customizing a base system.
- LFS provides no online repositories; sources are manually obtained, compiled and installed with make. (Several manual methods of package management exist, and are mentioned in LFS Hints).
- Arch provides these very same packages, plus systemd, a few extra tools and the powerful pacman package manager as its base system, already compiled for x86_64. Along with the minimal Arch base system, the Arch community and developers provide and maintain many thousands of binary packages installable via pacman as well as PKGBUILD build scripts for use with the Arch Build System. Arch also includes the makepkg tool for expediently building or customizing packages, readily installable by pacman.
- Judd Vinet built Arch from scratch, and then wrote pacman in C. Historically, Arch was sometimes humorously described simply as "Linux, with a nice package manager."
- Both Arch Linux and Gentoo Linux are rolling release systems, making packages available to the distribution a short time after they are released upstream.
- The Gentoo packages and base system are built directly from source code according to user-specified USE flags. Arch provides a ports-like system for building packages from source, though the Arch base system is designed to be installed as pre-built x86_64 binary. This generally makes Arch quicker to build and update, and allows Gentoo to be more systemically customizable.
- Arch only supports x86_64 while Gentoo officially supports x86 (i486/i686), x86_64, PPC/PPC64, SPARC, Alpha, ARM, MIPS, HPPA, S/390 and Itanium architectures.
- Gentoo's official package and system management tools tend to be rather more complex and "powerful" than those provided by Arch, and certain features which are at the very heart of Gentoo (USE flags, SLOTs, etc.) do not have any direct Arch Linux equivalent. Some of that is due to the fact that Arch is primarily a binary distribution, but differences in design philosophy also play a big role, with Arch taking a more principled stance in favor of architectural simplicity and avoiding over-engineering.
- Because both the Gentoo and Arch installations only include a base system, both are considered to be highly customizable. If comfortable with systemd, Gentoo users will also generally feel at ease with most other aspects of Arch.
GNU Guix System
- GNU Guix System has been inspired by NixOS in a way similar to how Arch has been inspired by CRUX.
- Both Arch Linux and Guix System are rolling release distributions, making packages available to the distribution a short time after they are released upstream. Guix System is however primarily a source-based distribution (although pre-built binaries exist and are called "substitutes"), while Arch is primarily a binary distribution.
- Arch uses pacman as package manager, whereas Guix System uses guix, which supports experimental packaging features not present in other distributions.
- Arch only supports x86_64, while Guix System officially supports several architectures.
- Arch uses systemd as init system, whereas Guix System uses the GNU Shepherd.
- Guix System breaks up with many traditional concepts of Unix, including the Filesystem Hierarchy Standard. For instance, many files that in traditional distributions are spread across different directories, in Guix System will be located somewhere under
- Arch might occasionally ship software that is non-free (often drivers), while Guix System ships only free software and is endorsed by the Free Software Foundation – although alternative repositories that ship non-free software for Guix exist.
- Arch expects the user directly to configure installed software packages, while Guix System encourages a global system configuration in Scheme, which in turn instantiates configuration files.
These distributions offer a broad range of advantages and strengths, and can be made to serve most operating system uses.
- Debian is the largest upstream Linux distribution with a bigger community and features stable, testing, and unstable branches, offering over 148 000 packages. The available number of Arch binary packages is more modest. However, when including the AUR, the quantities are comparable.
- Debian has a more vehement stance on free software but still includes non-free software in its non-free repos. Arch is more lenient, and therefore inclusive, concerning non-free packages as defined by GNU.
- Debian focuses on stringent testing of the Stable branch, which is "frozen" and supported up to five years. Arch packages are more current than Debian Stable, being more comparable to the Debian Testing and Unstable branches, and has no fixed release schedule.
- Debian is available for many architectures, including alpha, arm, hppa, i386, x86_64, ia64, m68k, mips, mipsel, powerpc, s390, and sparc, whereas Arch is x86_64 only.
- Arch provides more expedient support for building custom, installable packages from outside sources, with a ports-like package build system. Debian does not offer a ports system, relying instead on its large binary repositories.
- The Arch installation system only offers a minimal base, transparently exposed during system configuration, whereas Debian's methods, such as the use of apt tasks to install pre-selected groups of packages, offer a more automatically configured approach as well as several alternative methods of installation.
- Arch generally packages software libraries together with their header files, whereas in Debian header files have to be downloaded separately.
- Arch keeps patching to a minimum, thus avoiding problems that upstream are unable to review, whereas Debian patches its packages more liberally for a wider audience.
- Fedora is community developed, yet corporately backed by Red Hat; it is often presented as a testbed release system. Fedora packages and projects migrate to RHEL and some eventually become adopted by other distributions. Arch has no fixed releases, and does not serve as a testing branch for another distribution.
- Fedora packages use the RPM format with the DNF package manager. Arch uses pacman to manage its packages.
- Fedora refuses to include non-free software in official repositories due to its dedication to free software, though third-party repositories are available for such packages. Arch is more lenient in its disposition toward non-free software, leaving the discernment to the user.
- Fedora offers many installation options including a graphical installer as well as a minimal option. Fedora "spins" also provide alternative assortments of desktop environments to choose from, each with a modest assortment of default packages. Arch, on the other hand, only provides a few scripts meant to ease the process of a minimal base system install.
- Fedora has a scheduled release cycle, but officially supports discrete version upgrades with the FedUp tool. Arch is a rolling-release system.
- Arch features a ports system, whereas Fedora does not.
- Both Arch and Fedora are targeted at experienced users and developers. Both strongly encourage their users to contribute to project development.
- Fedora has earned much community recognition for integration of SELinux, GCJ compiled packages (to remove the need for Oracle's JRE), and prolific upstream contribution; Red Hat and thus, Fedora developers by extension, contribute the highest percentage of Linux kernel code as compared to any other project.
- Arch Linux provides what is widely regarded as the most thorough and comprehensive distribution wiki. The Fedora wiki is used in the original sense of the word "wiki", or a way to exchange information between developers, testers and users rapidly. It is not meant to be an end-user knowledge base like Arch's. Fedora's wiki resembles an issue tracker or a corporate wiki.
- Slackware uses BSD-style init scripts, whereas Arch uses systemd.
- Arch supplies a package management system in pacman which, unlike Slackware's standard tools, offers automatic dependency resolution and allows for more automated system upgrades. Slackware users typically prefer their method of manual dependency resolution, citing the level of system control it grants them, as well as Slackware's excellent supply of pre-installed libraries and dependencies.
- Arch is a rolling-release system. Slackware is seen as more conservative in its release cycle, preferring proven stable packages. Arch is more bleeding-edge in this respect.
- Arch Linux provides many thousands of binary packages within its official repositories, whereas Slackware official repositories are more modest.
- Arch offers the Arch Build System, an actual ports-like system, and also the AUR, a very large collection of PKGBUILDs contributed by users. Slackware offers a similar, though slimmer system at slackbuilds.org which is a semi-official repository of Slackbuilds, which are analogous to Arch PKGBUILDs. Slackware users will generally be quite comfortable with most aspects of Arch.
Sometimes called "newbie distros", the beginner-friendly distributions share a lot of similarities, though Arch is quite different from them. Arch may be a better choice if you want to learn about GNU/Linux by building up from a small base, as an installation of Arch installs few packages in comparison. Specific differences between distributions are described below.
- Ubuntu is a popular Debian-based distribution commercially sponsored by Canonical Ltd., while Arch is an independently developed system built from scratch.
- The two projects have very different goals and are targeted at a different user base. Arch is designed for users who desire a do-it-yourself approach, whereas Ubuntu provides a preconfigured system. Arch presents a simpler design from the base installation onward, relying on the user to customize it to their own specific needs. Many Arch users have started on Ubuntu and eventually migrated to Arch.
- Arch development is not biased towards any one particular user interface beyond what its community provides support for. Furthermore, Canonical's commercial nature has led them to some controversial decisions, such as the inclusion of advertisements in Unity's Dash menu and user data collection. Arch is an independent, community-driven project with no commercial agenda.
- Ubuntu moves between discrete releases every 6 months, whereas Arch is a rolling-release system.
- Arch offers a ports-like package build system and the Arch User Repository, where users can share source packages for the pacman package manager. Ubuntu uses the more complex apt, and allows redistribution of binary packages via Personal Package Archives.
- The two communities differ in some ways as well. The Arch community is much smaller and is strongly encouraged to contribute to the distribution. In contrast, the Ubuntu community is relatively large and can therefore tolerate a much larger percentage of users who do not actively contribute to development, packaging, or repository maintenance.
- Linux Mint was born as an Ubuntu derivative, and later added the LMDE (Linux Mint Debian Edition) that is instead based on Debian. On the other hand, Arch is an independent distribution that relies on its own build system and repositories.
- Mint includes several graphical tools for easier maintenance, called MintTools. Arch only provides simple command-line tools like pacman and leaves system management to be organized by the user.
- New versions of Mint are released every six months, about a month after Ubuntu. Each release is based on the most recent Ubuntu LTS and is supported for five years. Linux Mint Debian Edition (LMDE) is based on Debian Stable and only receives updates in Mint packages and security updates. Arch is instead a full rolling-release distribution.
openSUSE is centered around the RPM package format and its well-regarded YaST2 GUI-driven configuration tool. Arch does not offer such a facility. openSUSE may therefore be more appropriate for users who want a more GUI-driven environment, automatic configuration, or expected functionality out of the box while still allowing deep customization.
Mandriva Linux (formerly Mandrake Linux) was created in 1998 with the goal of making GNU/Linux easy to use for everyone; it is RPM-based and uses the urpmi package manager. Mageia is a Mandriva fork created by former Mandriva employees which opposes its parent distribution's commercial position, being a non-profit and community-driven project. Arch takes a simpler approach than Mandriva or Mageia, being text-based and relying on more manual configuration, and is aimed at intermediate to advanced users.
- The BSDs share a common origin and descend directly from the work done at UC Berkeley to produce a freely redistributable, free of cost, UNIX system. They are not GNU/Linux distributions, but rather, UNIX-like operating systems, and derived from the original AT&T UNIX code.
- Arch and the BSDs share the concept of a tightly-integrated base and ports system. However, unlike GNU/Linux distributions such as Arch, the BSDs' kernel and userland programs (such as the shell and core utilities like ls, cp, cat, and ps) are developed together in a single source repository.
- The BSD license is permissive, in contrast to the GPL, which has the stipulation that derivatives need to be released under the same license. Arch is released under the GPL.
