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. 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.
