Two major incidents over an hour in September 2026, on sandbox creation and on creating from snapshots.\n\n**Vercel Sandbox.** Active CPU billing, so waiting on model responses costs only memory. Tied to a Vercel team and project even when called from elsewhere, and access tokens reach the whole team.\n\n## Before you call either\n\n### E2B\n\n1. Set a timeout when you create a sandbox. The default is 5 minutes\n2. Pause rather than kill when you'll come back. Resume takes about a second and nothing is billed while paused\n3. Use `Secret.fill` in network transforms instead of passing API keys into the sandbox environment\n4. Pace sandbox creation. Hobby allows 1 a second and 20 running at once\n5. Move to the v2 sandbox endpoints. SDK 2.51.0 and later use them by default\n\n### Vercel Sandbox\n\n1. Call `sandbox.stop()` when the task is done. Memory bills until the session ends\n2. Use `Sandbox.getOrCreate` with a name so retries land in the same sandbox\n3. Set `networkPolicy` to `deny-all` for untrusted code. The default is allow-all\n4. Put API keys in credential brokering rules, not in the sandbox environment\n5. Pass `persistent: false` for one-off runs so no snapshot is stored or billed\n\n## Other comparisons with E2B or Vercel Sandbox\n\n- [Blaxel Sandboxes vs E2B](https://www.anchorterminal.com/compare/blaxel-sandboxes-vs-e2b.md)\n- [Blaxel Sandboxes vs Vercel Sandbox](https://www.anchorterminal.com/compare/blaxel-sandboxes-vs-vercel-sandbox.md)\n- [Cloudflare Sandbox SDK vs E2B](https://www.anchorterminal.com/compare/cloudflare-sandbox-sdk-vs-e2b.md)\n- [Cloudflare Sandbox SDK vs Vercel Sandbox](https://www.anchorterminal.com/compare/cloudflare-sandbox-sdk-vs-vercel-sandbox.md)\n- [Daytona vs E2B](https://www.anchorterminal.com/compare/daytona-vs-e2b.md)\n- [Daytona vs Vercel Sandbox](https://www.anchorterminal.com/compare/daytona-vs-vercel-sandbox.md)\n- [E2B vs Modal Sandboxes](https://www.anchorterminal.com/compare/e2b-vs-modal-sandboxes.md)\n- [E2B vs Runloop Devboxes](https://www.anchorterminal.com/compare/e2b-vs-runloop.md)\n- [Modal Sandboxes vs Vercel Sandbox](https://www.anchorterminal.com/compare/modal-sandboxes-vs-vercel-sandbox.md)\n- [Runloop Devboxes vs Vercel Sandbox](https://www.anchorterminal.com/compare/runloop-vs-vercel-sandbox.md)\n", "meta": { "attribution": "Anchor Terminal (https://www.anchorterminal.com)", "docs": "https://www.anchorterminal.com/docs/", "generatedAt": "2026-10-05", "license": "CC-BY-4.0", "method": "https://www.anchorterminal.com/benchmark/", "methodology": "0.3", "openapi": "https://www.anchorterminal.com/openapi.json", "preview": false, "run": "2026-10-01", "runLabel": "October 2026 research run" }, "page": { "breadcrumbs": [ { "name": "Home", "url": "https://www.anchorterminal.com/" }, { "name": "Compare", "url": "https://www.anchorterminal.com/compare/" }, { "name": "E2B vs Vercel Sandbox", "url": "" } ], "description": "Vercel Sandbox has a score of 69.6 (B) against E2B's 68.5 (B).
