Vercel Sandbox

Run code evaluators in ephemeral compute on Vercel’s infrastructure.

Vercel Sandbox runs each evaluation in ephemeral compute on Vercel’s infrastructure, scoped to a specific Vercel team and project. It supports both Python and TypeScript evaluators.

Setup

Vercel Sandbox needs three values:

Value	What it is	Where to find it
VERCEL_TOKEN	A personal access token	Account Settings → Tokens
VERCEL_PROJECT_ID	The project’s resource ID	Project Settings → General
VERCEL_TEAM_ID	The team’s resource ID	https://vercel.com/teams/<your-team>/settings#team-id

Then:

1. Add the credentials to Phoenix. Open Settings → Sandboxes, find the Vercel Sandbox row, click the gear icon, and paste each value into the matching field. You can also set them as environment variables on the Phoenix server.
2. Create a configuration. In Sandbox Configurations, click New Sandbox, pick Vercel Sandbox, choose the language (Python or TypeScript), set the timeout and any environment variables or dependencies, and save.
