Manage a Browser Session

Closing a session

Always close the session when your automation is done to free up cloud resources and avoid hitting concurrency limits.

Puppeteer

await browser.close();

Playwright

await browser.close()

Reusing a session across multiple operations

Each puppeteer.connect() or connect_over_cdp() call starts a new session. If you run multiple operations sequentially (for example, in an agent workflow), reuse the same connection — otherwise cookies, local storage, and page state are lost between steps.

Recommended pattern — session singleton:

Puppeteer

// session.js
const puppeteer = require('puppeteer-core');

let _browser = null;
let _page = null;

async function getSession(token, profileId) {
  if (_browser && _browser.isConnected()) {
    return { browser: _browser, page: _page };
  }

  const url = `https://cloudbrowser.gologin.com/connect?token=${token}&profile=${profileId}`;
  _browser = await puppeteer.connect({ browserWSEndpoint: url, defaultViewport: null });
  const pages = await _browser.pages();
  _page = pages[0] || await _browser.newPage();

  return { browser: _browser, page: _page };
}

async function closeSession() {
  if (_browser) {
    await _browser.close();
    _browser = null;
    _page = null;
  }
}

module.exports = { getSession, closeSession };

Playwright

# session.py
from playwright.async_api import async_playwright, Browser, Page

_browser: Browser | None = None
_page: Page | None = None
_playwright = None

async def get_session(token: str, profile_id: str):
    global _browser, _page, _playwright

    if _browser and _browser.is_connected():
        return _browser, _page

    url = f'https://cloudbrowser.gologin.com/connect?token={token}&profile={profile_id}'
    _playwright = await async_playwright().start()
    _browser = await _playwright.chromium.connect_over_cdp(url)
    pages = _browser.contexts[0].pages if _browser.contexts else []
    _page = pages[0] if pages else await _browser.new_page()

    return _browser, _page

async def close_session():
    global _browser, _page, _playwright
    if _browser:
        await _browser.close()
    if _playwright:
        await _playwright.stop()
    _browser = None
    _page = None
    _playwright = None

Handling disconnects

Network interruptions or cloud-side timeouts can drop the connection. Check connectivity before each operation and reconnect if needed:

Puppeteer

if (!browser.isConnected()) {
  // reconnect
  const { browser: b, page: p } = await getSession(token, profileId);
}

Concurrency

Each active session counts against your plan’s concurrency limit. To avoid errors:

• close sessions when done
• do not connect to the same profile from multiple processes simultaneously
