Whonix is a complete operating system. It consists of two virtual machines - Whonix-Gateway and Whonix-Workstation - which are designed to be used on a host operating system (OS). The host OS supporting Whonix is usually the one installed on the user's computer, but OS's installed on external drives will also work. Users choose the preferred Whonix configuration and may use either a Type I hypervisor (Qubes-Whonix), or a Type II hypervisor like KVM and Virtualbox.
Security by Isolation
Whonix is divided into two parts: Whonix-Workstation for work activities and Whonix-Gateway to enforce all Internet traffic routing via the Tor network. This security by isolation configuration averts many threats posed by malware, misbehaving applications, and user error.
Online Anonymity via Tor
Whonix relies on the Tor network to protect a user's anonymity online; all connections are forced through Tor or otherwise blocked. Tor helps to protects users by bouncing communications around a distributed network of relays run by volunteers all around the world. Without advanced, end-to-end, netflow correlation attacks, anybody watching a user's Internet connection cannot easily determine the sites visited, and those sites cannot learn the user's physical location. 
To learn more about Tor, read the official documentation on the Tor website:
Based on Debian
In simple terms, Whonix is just a collection of configuration files and scripts. Whonix is not a stripped down version of Debian; anything possible in "vanilla" Debian GNU/Linux can be replicated in Whonix. Likewise, most problems and questions can be solved in the same way. For example: "How do I install xrandr on Whonix?" -- "The same way as in Debian
|Tip: Since Ubuntu is a Debian derivative, online help for Ubuntu most often works for Whonix.|
Each Whonix release is based on a particular version of Debian:
|Whonix version||Debian Version||Debian Codename|
Note that there is not a specific, fixed Whonix release schedule. A new stable release only become available when it is deemed ready. Interested users can query the Whonix phabricator manifest to track developer progress.

To learn more about Whonix and to determine whether it is a suitable solution in your circumstances, the user is recommended to read:
- The Warning page to understand the security limitations of Whonix and Tor.
- Further information about Whonix Features.
- The implied Trust placed in Whonix when it is used.
- The Security Guide, Advanced Security Guide and Design documents detailing the Whonix specifications, threat model and implementation.
- Other relevant Documentation entries explaining in detail how to use Whonix safely.
Footnotes / References
- Current practical, low-latency, anonymity designs like Tor fail when the attacker can see both ends of the communication channel (traffic going into and out of the Tor network). If both flows are visible, simple statistics can determine whether they match up.
- For example, for the next release use the tag "Whonix 14" and status "Open".
