## AI overview

Vercel Sandbox now supports installing and running Docker inside isolated sandboxes. This enables building containers, running containerized services such as Redis or Postgres, validating images, and previewing containerized applications without modifying the host system. Persistent sandboxes retain Docker installations and pulled images between sessions.

## Source excerpt

Update (August 2026): Vercel Sandbox now runs on Vercel Managed Images. Starting with SDK v3, new sandboxes default to the Ubuntu-based vercel/sandbox/universal:latest, where dnf isn't available. The example below applies to the deprecated Amazon Linux runtimes; on Ubuntu, install Docker with apt-get. See the announcement for details. Vercel Sandbox now supports installing and running Docker inside a sandbox. An agent can build containers, install system packages, and modify files without touching your host system. Install Docker, start the daemon, and serve a containerized application: Docker in a Sandbox is useful for running containerized services like Redis or Postgres as test dependencies, validating container images before deploying, or previewing applications served from a container. Combined with persistent sandboxes, the Docker installation and pulled images carry over between sessions. As well as adding support for Docker, sandboxes now support FUSE filesystem drivers and VPN clients, unlocking unlimited capabilities to what can be built.
