Undo the agent's worst night

Business boxes snapshot themselves as the agent works: when it starts a task, every hour and every day. Roll the whole box back in seconds, or copy one file out of last Tuesday. From $149 a month.

From $19 a month · Docker and sudo included · Cancel from the dashboard any time

Snapshots of shipyard: automatic ones taken as the agent works, hourly ones, and a checkpoint named Before the Postgres 18 upgrade, each with Roll back and Get files back.

Let the agent swing big

  • Let the agent take risks

    Migrations, dependency upgrades, a rewrite: a snapshot was taken when it started. If it goes wrong, you roll back to the moment before it began, in seconds.

  • Back in seconds

    The box pauses for 2 to 6 seconds and your files, packages and volumes come back as they were. Keys, subscriptions, previews and links stay current.

  • Pull back one file and keep the rest

    Copy a file or a folder back into ~/restored and leave everything else as it is.

  • Checkpoints with names

    Save the state before a big change under a name you will recognise, and keep it until you delete it.

Questions about this

What does rolling back undo?

Everything on the box's disk after the snapshot: files, packages, Docker images and volumes. Newer snapshots go with it. Your SSH keys, subscriptions and share links stay as they are now.

Can I have snapshots on the Start, Pro or Max box plans?

Snapshots come with Business and Business Plus. Change a box's plan in the dashboard or start a Business box.

How is a clone different from a snapshot?

A snapshot is a moment inside the same box. A clone is a second box on its own plan, starting from a copy of this one's disk. Subscriptions and Sallyport access stay with the original; the copy connects its own.
