Bazaar is a distributed revision control system, similar to Git, originally developed by Canonical.
Launchpad offered Bazaar code hosting with a web frontend called Loggerhead for browsing the code.
Due to decreased usage and maintenance costs, Launchpad will phase out support for Bazaar, with an imminent shutdown of Loggerhead and a complete discontinuation by September 1, 2025.
Users are urged to migrate their repositories from Bazaar to Git by the deadline and can find detailed steps for conversion on Launchpad's blog.
