Python 3.15 now available as a Vercel Managed Image

Python 3.15 is now available as a Vercel Managed Image for Vercel Sandbox.

To run a sandbox with Python 3.15, select vercel/sandbox/python:3.15 using the image option in either SDK or the --image flag in the CLI.

sandbox.ts

import { Sandbox } from '@vercel/sandbox';

const sandbox = await Sandbox.create({ image: 'vercel/sandbox/python:3.15' });
const version = await sandbox.runCommand('python', ['--version']);
console.log(`Python version: ${await version.stdout()}`);

Create a sandbox with Python 3.15 and print its version.

The default universal image (vercel/sandbox/universal:latest) still ships Python 3.14 and is scheduled to switch to Python 3.15 on December 16, 2026.

Learn more in the Vercel Sandbox images documentation.
