Offload heavy builds, full test suites and parallel experiments from the local machine to Vercel Sandboxes with the `vercel sandbox` CLI. Use when a local machine is overloaded or shared by several agents, when a test suite should be sharded, or when many tasks should run side by side without consuming local CPU, memory or disk.
