New Sandboxes can launch from that snapshot, providing immediate access to pre-installed dependencies and configured environments. Link to heading Key capabilities Create a snapshot from any running Sandbox with sandbox.snapshot() Launch new Sandboxes from snapshots via source: { type: 'snapshot', snapshotId } Reuse the same snapshot with multiple Sandboxes for parallel testing and experimentation import { Sandbox } from '@vercel/sandbox' ; const sandbox = await Sandbox .…
