Vercel Sandbox Persistence Feature Reaches General Availability (GA)

Vercel Sandbox has launched its Persistence feature, which automatically saves and restores file system state across sessions, in general availability (GA). Now you can maintain work state without separate snapshot management, and the persistence feature is enabled by default.

Each sandbox can have a custom name that serves as a unique reference within a project. Calling Sandbox.create() automatically snapshots and saves the file system, and Vercel automatically manages sessions without interrupting your workflow.

However, snapshot storage capacity is billed separately from compute costs. Therefore, for ephemeral workloads, you can minimize storage costs by using the persistent: false option or passing the --non-persistent flag in the CLI.

Stopped sandboxes can be automatically resumed via Sandbox.get(), with a new session starting from the point of the latest snapshot.

Key updates and additional features include the following:

• Sandbox.fork(): Create a new sandbox based on an existing sandbox
• Sandbox.getOrCreate(): Get or create a sandbox (Idempotent)
• Sandbox.delete(): Permanently delete a sandbox
• Improved sandbox.stop(): Returns snapshot metadata and CPU/network transfer volume
• Lifecycle hooks: Support for onCreate and onResume hooks
• Tags: Assign custom attributes for multi-tenant tracking
