How to Connect with Playwright (Node.js)
Connect directly to Browserbase's remote browser WebSocket endpoint without running Chromium locally:
import { chromium } from 'playwright';
// Connect to Browserbase cloud browser instance
const browser = await chromium.connectOverCDP(
'wss://browserbase.example.com/cdp?token=YOUR_API_KEY'
);
const context = await browser.newContext();
const page = await context.newPage();
await page.goto('https://nowsecure.nl', { waitUntil: 'networkidle' });
// Automated anti-bot bypass & CAPTCHA solving operates transparently
const title = await page.title();
