Multilogin + Puppeteer (Node.js)

JavaScript teams often standardize on Puppeteer instead of Playwright. Multilogin still exposes a Chromium CDP endpoint — attach with puppeteer.connect, never launch raw Chrome when profile isolation matters.

Setup

npm init -y
npm install puppeteer-core axios
export MLX_TOKEN="your_token"
export MLX_PROFILE_ID="profile_uuid"

Launch + attach + cleanup

const axios = require("axios");
const puppeteer = require("puppeteer-core");

const MLX = process.env.MLX_API || "https://api.multilogin.com";
const TOKEN = process.env.MLX_TOKEN;
const PROFILE = process.env.MLX_PROFILE_ID;
const headers = { Authorization: `Bearer ${TOKEN}` };

async function sleep(ms) {
  return new Promise((r) => setTimeout(r, ms));
}

async function startProfile() {
  for (let i = 0; i < 5; i++) {
    try {
      const { data, status } = await axios.post(
        `${MLX}/profile/start`,
        { profile_id: PROFILE, headless: false },
        { headers, timeout: 90_000 }
      );
      if (status === 429) {
        await sleep(2 ** i * 1000);
        continue;
      }
      const cdp = data.cdp_url || data.wsUrl;
      if (cdp) return cdp;
      await sleep(2000);
    } catch (e) {
      await sleep(2 ** i * 1000);
    }
  }
  throw new Error("CDP URL not available");
}

async function stopProfile() {
  await axios.post(`${MLX}/profile/stop`, { profile_id: PROFILE }, { headers });
}

async function main() {
  const cdpUrl = await startProfile();
  const browser = await puppeteer.connect({ browserWSEndpoint: cdpUrl, defaultViewport: null });
  try {
    const pages = await browser.pages();
    const page = pages[0] || (await browser.newPage());
    await page.goto("https://example.com", { waitUntil: "domcontentloaded", timeout: 45_000 });
    console.log(await page.title());
  } finally {
    browser.disconnect();
    await stopProfile();
  }
}

main().catch((err) => {
  console.error(err);
  process.exit(1);
});

Node vs Python at scale
