Vercel Sandbox for Node.js now uses Node.js 24 by default. This keeps the Node.js runtime aligned with the latest Node.js features and performance improvements.

If you don’t explicitly configure a runtime, Sandbox will use Node.js 24 (as shown below).

import { Sandbox } from "@vercel/sandbox";
async function main() {
  const sandbox = await Sandbox.create();
  const version = await sandbox.runCommand("node", ["-v"]);
  console.log(`Node.js version: ${await version.stdout()}`);
}
main().catch(console.error);
