Vercel Sandbox ships Managed Images: agents preinstalled, zero setup
Sandbox.create() now boots a default image with Node 24, Python 3.14 and coding agents baked in — plus pinned runtimes and custom OCI images you can share.

The Universal image is the new default
Call `Sandbox.create()` with no `image` and it now boots `vercel/sandbox/universal:latest` — Ubuntu preloaded with Node.js 24 LTS, Python 3.14, coding agents and common CLI utilities. Agent sandboxes start with nothing to `npm install` or `pip install`.
Pin a runtime or bring your own image
Need a locked toolchain? Pass `vercel/sandbox/node:22|24|26`, `python:3.14`, `arch`, or `ubuntu`. Or `vercel vcr build . repo:latest --push` any OCI image to Vercel Container Registry and boot straight into it — reuse the same image you already build for CI.
Share images across teams — or make them public
VCR repos can be shared with your team or marked public, so a sandbox can `create({ image: 'other-team/project/repo:latest' })` from someone else's image. It's the same mechanism Vercel uses to serve its own managed images to everyone.
