Python SDK for Vercel Sandbox

Python SDK for Vercel Sandbox

This is a minimal Python SDK that mirrors the core features of the TypeScript SDK:

• Create sandboxes
• Run commands (detached or wait for completion)
• Stream command logs
• Read/Write files, mkdir
• Stop sandbox
• Resolve exposed port domain

Quickstart

pip install vercel-sandbox

Or locally:

pip install -e .

Example

import asyncio
from vercel.sandbox import AsyncSandbox as Sandbox

async def main():
    async with await Sandbox.create(
        source={"type": "git", "url": "https://github.com/vercel/sandbox-example-next.git"},
        resources={"vcpus": 4},
        ports=[3000],
        timeout=600_000,
        runtime="node22",
    ) as sandbox:
        print("Installing dependencies...")
        result = await sandbox.run_command("npm", ["install", "--loglevel", "info"])  # waits
        if result.exit_code != 0:
            raise SystemExit("install failed")

        print("Starting dev server...")
        cmd = await sandbox.run_command_detached("npm", ["run", "dev"])  # detached
        print("Visit:", sandbox.domain(3000))

asyncio.run(main())

Using or not using the context manager

# Preferred: automatic cleanup
async with await Sandbox.create(timeout=60_000, runtime="node22") as sandbox:
    await sandbox.run_command("echo", ["hello"])

# Manual cleanup
sandbox = await Sandbox.create(timeout=60_000, runtime="node22")
try:
    await sandbox.run_command("echo", ["hello"])
finally:
    await sandbox.stop()
    await sandbox.client.aclose()

Authentication

The SDK prefers Vercel OIDC tokens when available:

• Local: use vercel env pull and place credentials in a .env file (auto-loaded).
• Alternatively provide VERCEL_TOKEN, VERCEL_TEAM_ID, and VERCEL_PROJECT_ID.

Environment variables

• VERCEL_OIDC_TOKEN plus VERCEL_TEAM_ID and VERCEL_PROJECT_ID
• or VERCEL_TOKEN, VERCEL_TEAM_ID, VERCEL_PROJECT_ID
