Vercel Drives Now Generally Available for Persistent Agent Storage in Sandbox

Vercel Drives is now generally available for Vercel Sandbox, providing persistent storage that keeps an agent’s files independent of its execution environment. This allows agents to continue working with the same files even when they switch to new environments with different tools, runtimes, or compute resources.

How It Works

Agents can create a drive once and mount it when creating a sandbox. Everything mounted under the specified path (e.g., /workspace) persists on the drive, while other files belong to the sandbox. When a new sandbox mounts the same drive, it finds the repository and any other files exactly where the previous run left them.

Sharing and Forking

The feature supports sharing state across multiple sandboxes:

• Read-only sharing: One agent can build a dataset on a drive, and other agents can mount read-only copies to analyze data or generate reports without rebuilding it.
• Forking: Agents can fork a drive to explore different approaches independently. Each fork starts with the original contents but provides its own writable workspace, allowing parallel experimentation without affecting the original drive. Forks do not merge back into the original.

Availability and Limits

Vercel Drives is available on all plans. Default storage capacity is 1 TiB (or 1 GiB on the Hobby plan), with up to 16 TiB available. Users can configure snapshots and limits via the documentation.
