We started Mallard to make it easier to share our agent sessions and build things together. We spend much of our working day talking to Claude and Codex. Those conversations include the ideas, designs, and decisions behind our work. However they often stay on one machine, without backups or an easy way to share them.

3 months. 10 accounts on 20× plans. 100 billion tokens later, Mallard finally hatched.

Share and back up agent sessions using Cloudflare R2, Dropbox, or Mallard Cloud.

Explore the discussions and design decisions behind PRs, including Mallard’s hatching logs.

Pull and resume sessions in Codex or Claude Code with the original context.

For teams, Anthropic internally uses cloud VMs and Claude Tag so that teammates can work in shared agent conversations and pick up where others left off. Mallard lets teams achieve the same goal at almost zero cost, without any cloud VMs.

We want Mallard to be free and easy to use for everyone, rich or poor.

We built a lightweight version of GIT and reworked our storage protocol, removing CAS so Mallard can work with any cloud storage that supports LIST and PUT APIs. Bring your own storage or use Mallard Cloud. No Git server or expensive sandbox required.

We also added one-click sign-in for Dropbox and Cloudflare R2, so anyone can connect their own cloud storage to Mallard in just a few clicks.

We don’t think the internet, recommendation algorithms, or AI should be in the hands of just a few people. We hope Mallard helps more people share their work, find an audience, and have their voices heard.
