Drives for Vercel Sandbox in Private Beta
By Steven Van ·
Vercel Sandbox drives keep agent workspaces, repos and build output alive across disposable sandbox runs, free during the Pro and Enterprise beta.
Vercel Sandbox now supports Vercel Drives in private beta: persistent storage that can be mounted into a sandbox and kept independent of that sandbox's lifecycle. A drive is created once, then mounted at a configurable path when a sandbox starts; when the sandbox stops, the drive stays available to attach to a later run, so cloned repositories, dependencies, build outputs, or an agent's workspace do not have to be rebuilt each time.
- A sandbox can mount up to 4 drives, each defaulting to 1 TiB, with a 16 TiB maximum quota (Vercel Support can raise this further on request).
- Drives can be mounted read-write or read-only, but during the beta a drive can only be mounted read-write by one sandbox at a time; support for multiple readers is coming.
- Available to Enterprise and Pro plans by signing up for the waitlist, using the beta SDK or CLI. Drives are free to use during the private beta.
