Does Launchpad Branches use Git or Bazaar?

Launchpad Branches hosts source code using Git. The page states plainly that "Launchpad can host your project's source code using the Git version control system," and it also imports thousands of Git projects. Bazaar, the older system, is on its way out: the page carries the notice "Bazaar will be deprecated in September 2025." So if you are starting a new project on Launchpad, choose Git.

What the page tells you about the version control setup

The Breezy version number is worth noting because Breezy is the successor to Bazaar. Its presence alongside a Git-first hosting model reflects a platform that still carries legacy tooling while directing new work toward Git.

Why the distinction matters for you

If you are deciding where to push a new branch, the answer is Git. Bazaar still appears in the ecosystem, but the September 2025 deprecation date means building new work on it carries a known expiry. Migrating later costs more than starting on Git now.

If you already have Bazaar branches hosted on Launchpad, the deprecation notice is your signal to plan a move to Git before that date. The page does not describe a migration path, so treat the notice as a deadline rather than a set of instructions.

What else Launchpad Branches does

Beyond hosting, the page highlights two related capabilities:

• Importing Git projects — Launchpad imports thousands of Git projects, so you can bring existing repositories in rather than starting from scratch.
• Building Ubuntu packages from branches — Launchpad can build Ubuntu packages directly from branches using recipes, which links your source branches to package output.

The page also surfaces activity signals: most active projects in the last month, recent imports, recently registered branches, and recently changed branches. These are useful if you want to see what is actively maintained before choosing where to contribute or host.

Practical takeaway

Use Git for anything new on Launchpad Branches. Treat Bazaar as legacy with a September 2025 end date, and if you still depend on it, start planning the move now. For package work, the recipes feature lets branches feed directly into Ubuntu package builds, which is the main reason to host on Launchpad rather than a plain Git remote.
