There are a lot of reasons to choose Debian as your operating system –
as a user, as a developer, and even in enterprise environments. Most
users appreciate the stability, and the smooth upgrade processes
of both packages and the entire distribution. Debian is also widely
used by software and hardware developers because it runs on numerous
architectures and devices, offers a public bug tracker and other tools
for developers. If you plan to use Debian in a professional environment,
there are additional benefits like LTS versions and cloud images.
Debian is made of free and open source software and will always be 100%
free. Free for anyone to use, modify, and
distribute. This is our main promise to our users. It's also free of cost.
Debian is stable and secure.
Debian is a Linux-based operating system for a wide range of devices including
laptops, desktops and servers. We provide a reasonable default configuration for
every package as well as regular security updates during the packages' lifetimes.
Debian has extensive Hardware Support.
Most hardware is supported by the Linux kernel which means that
Debian will support it as well. Proprietary drivers for hardware
are available if necessary.
Debian offers a flexible Installer.
Our Live
CD is for everyone who wants to give Debian a try before
installing it. It also includes the Calamares installer which makes
it easy to install Debian from the live system. More experienced
users can use the Debian installer with more options for fine-tuning,
including the possibility to use an automated network installation
tool.
Debian provides smooth Upgrades.
It's easy to keep our operating system up-to-date, whether you want
to upgrade to a completely new release or just update a single package.
Debian is the Base for many other Distributions.
Many popular Linux distributions, like Ubuntu, Knoppix, PureOS or Tails,
are based on Debian. We provide all the tools so that everyone can
extend the software packages from the Debian archive with their own
packages if needed.
The Debian Project is a Community.
Everyone can be a part of our community; you don't
have to be a developer or sysadmin. Debian has a
democratic governance
structure. Since all members of the Debian project have equal
rights, Debian cannot be controlled by a single company. Our
developers are from more than 60 different countries, and Debian
itself is translated into more than 80 languages.
Debian supports a long list of CPU architectures,
including amd64, i386, multiple versions of ARM and MIPS, POWER7, POWER8,
IBM System z and RISC-V. Debian is also available for niche architectures.
IoT and Embedded Devices
Debian runs on a wide range of devices, like the Raspberry Pi,
variants of QNAP, mobile devices, home routers and a lot of Single
Board Computers (SBC).
Huge Number of Software Packages
Debian has a large number of packages (currently in
stable: packages) which use the deb
format.
Different Releases
Besides our stable release, you can install newer software versions
by using the testing or unstable releases.
Public Bug Tracker
Our Debian bug tracking system (BTS) is publicly
available for everybody via a web browser. We do not hide our software
bugs, and you can easily submit new bug reports or join the discussion.
Debian Policy and Developer Tools
Debian offers high-quality software. To learn more about our
standards, read the policy
which defines technical requirements for every package included
in the distribution. Our Continuous Integration strategy involves
Autopkgtest (runs tests on packages), Piuparts (tests installation,
upgrade and removal), and Lintian (checks packages for inconsistencies
and errors).
Debian proves its reliability every day in thousands of real world
scenarios, ranging from single user laptops to super-colliders, stock
exchanges and the automotive industry. It's also popular in the academic
world, in science and in the public sector.
Debian has many Experts.
Our package maintainers do not only take care of the Debian packaging
and incorporating new upstream versions. Often they're experts
on the application itself and therefore contribute to upstream
development directly.
Debian is secure.
Debian offers security support for its stable releases. Many other
distributions and security researchers rely on Debian's security tracker.
Long Term Support
Debian's free of charge Long Term Support
(LTS) version extends the lifetime of all Debian
stable releases to at least 5 years. Additionally, the commercial
Extended LTS
initiative supports a limited set of packages for more than 5 years.
Cloud Images
Official cloud images are available for all major cloud platforms. We also
provide the tools and configuration so you can build your own customized
cloud images. You can also use Debian in virtual machines on the desktop or
in a container.
