How to Connect with Playwright (Node.js)
Connect directly to Lightpanda's remote browser WebSocket endpoint without running Chromium locally:
import { chromium } from 'playwright';
// Connect to Lightpanda cloud browser instance
const browser = await chromium.connectOverCDP(
'wss://lightpanda.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();
console.log('Page Title:', title);
await browser.close();Comprehensive Analysis: Lightpanda
