Tails is Free Software: you can download, use, and share it with no restrictions.

The Tails source code is released under the GNU/GPL (version 3 or above) and is Copyright (C) Tails developers tails@boum.org. Any exception to this rule is documented either below or in the affected source file.

However, Tails includes non-free firmware in order to work on as much hardware as possible.

Source code

Most of the software included in Tails is taken directly from upstream Debian packages and is neither modified nor recompiled by Tails.

  • The source code of software that is specific to Tails is available in our Git repositories.

  • The source code of the Debian packages included in Tails is available in the APT snapshot that we created for that version of Tails.
