Cube and Proton are sunsetting

November 6, 2026

We are winding down Cube Computer and Proton Computer. Thank you for building with us. Please retrieve any files you want to keep before the deletion date that applies to your machines below.

This shutdown applies to Cube and Proton machines. Collab is not affected. Your shared account and sign-in will not be deleted as part of this shutdown.

Immediately

• New Cube and Proton machines can no longer be created.
• Your credit balance will no longer be drawn down.
• Credit top-ups are stopped. Subscription payments will no longer be collected.
• We plan to refund all payments made for Cube and Proton. Customers will receive an email detailing their refund soon.
• Existing machines remain usable, and paused machines can be resumed to retrieve your data until their deletion date.

All remaining Cube and Proton machines will be permanently deleted, along with the data stored on those machines. Retrieve your files by 11:59 p.m. Eastern on December 20.

Save your work

Open your existing machines in the Cube web app or the Proton dashboard. Older desktop versions may still show a billing prompt. Use the Cube web app to connect to or resume your existing Cube machine at no charge.

Open or resume each of your machines and copy the files you need to your own computer or another service. Make sure you have saved any uncommitted code and files that are not backed up elsewhere. You will not be able to retrieve data from a machine after it is deleted.

If you need help retrieving your files or have a question about a refund, contact hi@cube.computer.
