Bazaar is written in the Python programming language, with packages for major Linux distributions, Mac OS X and Microsoft Windows. Bazaar is free software and in 2008 became part of the GNU Project.^[3][4] It was used by Canonical for their Launchpad code hosting website. The last release was in 2016. In 2025 Canonical announced the retirement of Bazaar.^[5] Breezy is a fork of Bazaar.
