[**Vercel Sandbox**](https://vercel.com/docs/vercel-sandbox) runs code in ephemeral compute on Vercel's infrastructure, scoped to a Vercel team and project. Phoenix uses it as a hosted backend for both Python and TypeScript [code evaluators](/docs/phoenix/evaluation/server-evals/code-evaluators). It's a good fit when your team is already on Vercel and you'd like sandbox usage to roll up under the same billing and access controls.

## Configure

1. Create a token in the [Vercel dashboard](https://vercel.com/account/tokens) and note your team and project IDs.
2. Add `VERCEL_TOKEN`, `VERCEL_PROJECT_ID`, and `VERCEL_TEAM_ID` from **Settings → Sandboxes**.

See [Settings → Sandboxes → Vercel Sandbox](/docs/phoenix/settings/sandboxes/vercel) for full configuration details and [Sandbox Backends](/docs/phoenix/self-hosting/features/sandbox-runtimes) for self-hosting setup.
