Filesystem snapshots supported on Vercel Sandboxes
Vercel Sandboxes now support filesystem snapshots to capture and reuse complete filesystem state across multiple isolated runs. This eliminates repeated setup for expensive operations like dependency installation and builds, allowing you to create an environment once and launch new Sandboxes from that snapshot using the Sandbox API.
now supports filesystem snapshots to capture your state. You can capture a Sandbox's complete filesystem state as a snapshot and launch new Sandboxes from that snapshot using the Sandbox API.Vercel Sandbox
This eliminates repeated setup when working with expensive operations like dependency installation, builds, or fixture creation. Create the environment once, snapshot it, then reuse that exact filesystem state across multiple isolated runs.
Snapshots capture the entire filesystem of a running Sandbox. New Sandboxes can launch from that snapshot, providing immediate access to pre-installed dependencies and configured environments.
