## AI overview

Vercel Sandboxes now support custom images in public beta. Users can provide a custom root filesystem with their own operating system, toolchain, and dependencies. Images are pulled from Vercel Container Registry, and the feature is designed to preserve cold start performance through precompiled snapshots.

## Source excerpt

Vercel Sandboxes now supports custom images. Launching in public beta today, images allow Sandboxes to start with your own custom root filesystem. Images are pulled from Vercel Container Registry, so anything you docker push is immediately available. Bring your own OS, toolchain and dependencies into the Sandbox without needing to spin up compute and create Snapshots. Images in the background for Fluid Compute and boot from a precompiled snapshot in the same format as our Sandbox Snapshots - so you get the convenience of a custom filesystem without sacrificing cold start performance.
