AI BriefingVercel Sandbox Begins Supporting Custom Images
Key point
Vercel Sandbox now supports custom images, allowing users to instantly configure the OS and toolchain of their choice.
Details
Vercel Sandbox has started supporting Custom Images in public beta today. Users can now create Sandboxes with their own root filesystem.
Images are pulled from the Vercel Container Registry, and images pushed via docker push are immediately available. Without needing to allocate separate compute resources or create snapshots, users can apply their desired OS, Toolchain, and dependencies directly to the Sandbox.
In particular, this update boots as a pre-compiled snapshot in the background for Fluid Compute, enabling fast execution with custom filesystems while avoiding Cold Start performance degradation.
