Give your stateful apps durable disk with Persistent Volumes, dedicated block storage that attaches to a single application and survives restarts, redeploys, and image changes.
Durable block storage
Each volume is a dedicated block device, mounted read-write at the path you choose, such as /data. Pick any size from 10 GB to 50 GB per volume. Your data persists across every deploy, so databases, queues, and file stores keep their state between releases.
Attach at create, or any time after
Create a volume up front and mount it when you create an app, or add one to an existing app and mount it at any path. Detaching a volume never deletes its data, so you can move a disk between apps without losing a byte.
Built for stateful workloads
An app with a volume runs as a single instance, so your data always has one writer. Stateless apps keep scaling horizontally exactly as before.
Volumes are available on the Pro plan, with 100 GB of total volume storage per team. Open any app and find the Volumes section to create your first one.
