All you need to know about cloud browser is an url which you need to pass to your automation tool:
https://cloudbrowser.gologin.com/connect?token=${token}&profile=${params.profileId} It’s a websocket url that will establish connection to control the browser You need to provide your dev token and profile id (optional). If you dont pass a profile id - it will create new profile

​
Example with Puppeteer

const puppeteer = require('puppeteer-core');

(async () => {
  // Your GoLogin dev token
  const token = 'your_token_here';
  
  // Optional: profileId (if you want to use an existing profile)
  const profileId = 'your_profile_id'; // Remove this line if you want to create a new profile
  
  // Construct the cloud browser URL
  const cloudBrowserUrl = `https://cloudbrowser.gologin.com/connect?token=${token}${profileId ? `&profile=${profileId}` : ''}`;
  
  // Connect to the browser
  const browser = await puppeteer.connect({
    browserWSEndpoint: cloudBrowserUrl,
    defaultViewport: null
  });
  
  // Create a new page
  const page = await browser.newPage();
  
  // Navigate to a website
  await page.goto('https://example.com');
  
  // Perform your automation tasks here
  const title = await page.title();
  console.log('Page title:', title);
  
  // Example: take a screenshot
  await page.screenshot({ path: 'screenshot.png' });
  
  // Close the browser when done
  await browser.close();
})();
