Vercel Sandboxes Adds File System Snapshot Support

Vercel Sandbox now supports file system snapshots. You can capture the entire file system state of a sandbox as a snapshot and instantly launch a new sandbox from that snapshot via the Sandbox API.

This feature eliminates the need to repeat time-consuming tasks such as installing dependencies, building, and creating fixtures. Once you've set up an environment, you can create a snapshot and reuse the same file system state across multiple independent execution environments.

Key features include:

• Creating a snapshot of a running sandbox via sandbox.snapshot()
• Launching a new sandbox based on a snapshot using source: { type: 'snapshot', snapshotId }
• Reusing the same snapshot across multiple sandboxes for parallel testing and experimentation
