Browser for AI agents

The AI agent browser that can do real work

An AI agent browser is a cloud browser built for autonomous agents: one device fingerprint, one residential proxy and one set of cookies on every run. It clicks, types and uploads in a real browser, and next week’s run starts already signed in.

Your agent signs in once, then every run starts signed in

Cookies, device fingerprint and residential IP come back as one identity on every run, so the site sees the same returning user on run 40 as on run 1.

Mondayrun 1Signed in

The agent signs in once, a person types the verification code in the live session, and the profile is saved.

Same device, same address, same account. No login screen and nothing to hand back to a person.

Nothing has drifted. One account on one consistent device the whole time.

Everyone saves your cookies. Almost nobody saves the rest.

A device with a consistent fingerprint across every session

One profile, one identity: fingerprint, user agent and cookies handed back together, not put together from parts.

Build a self-learning agent, not a script that breaks on run two

Ask Claude for anything. When the page moves, the agent finds the new way and writes the fix down.

Building this yourself? See the agent browser CLI, or set up the MCP server and let Claude drive.

Connect it however your stack already works

The same session sits behind Playwright, Puppeteer and Python over CDP, so your browser automation code drives it unchanged. Every tab below ran as shown against Gologin Cloud Browser.

  1. Step 01

    Get your token

    Sign up with Google and copy your key from the dashboard. Free, no card.

  2. Step 02

    Create a profile

    One click in the dashboard, or one API call. The profile keeps the device, the IP and the login.

  3. Step 03

    Run the script

    Install the library and run the script below with your token and profile id. Prefer to let Claude drive? Set up the MCP server. More in the getting started guide.

Install
npm install playwright-core
Run
GOLOGIN_TOKEN=your_token GOLOGIN_PROFILE_ID=your_profile_id node scrape.mjs
Connects to
wss://cloudbrowser.gologin.com/connect?token=…&profile=…
import { chromium } from "playwright-core";

const token = process.env.GOLOGIN_TOKEN;
const profileId = process.env.GOLOGIN_PROFILE_ID;
const endpoint = `wss://cloudbrowser.gologin.com/connect?token=${token}&profile=${profileId}`;

const browser = await chromium.connectOverCDP(endpoint);
const page = await browser.contexts()[0].newPage();

await page.goto("http://quotes.toscrape.com/scroll");
await page.waitForSelector(".quote");

for (let i = 0; i < 30; i++) {
  const before = await page.locator(".quote").count();
  await page.evaluate(() => window.scrollTo(0, document.body.scrollHeight));
  try {
    await page.waitForFunction(
      (n) => document.querySelectorAll(".quote").length > n,
      before,
      { timeout: 3000 }
    );
  } catch {
    break;
  }
}

const quotes = await page.$$eval(".quote", (els) =>
  els.map((el) => ({
    text: el.querySelector(".text")?.textContent,
    author: el.querySelector(".author")?.textContent,
  }))
);
console.log(quotes.length, quotes[0]);

await page.close();
await browser.close();

Take the wheel mid-run, or let your own users take it

Every session has a live URL. Open it and you are inside the browser your agent is driving, however long it has been running.

  • Take the wheel yourself

    Open the live URL and you are in the same browser, same cookies, same address. Finish the step, close the tab, the run keeps going.

  • Hand over from your code

    Takeover is an API call, not a support ticket. Any moment, any live session, no restart and no second login.

  • Put it in your own product

    Embed the live session in your own dashboard. Your users drive a signed-in browser and never leave your product.

Building it in? Read the Live View docs, or see Cloud Browser UI.

Browser hours are cheap everywhere. Traffic is not.

On a real agent workload, traffic is the biggest line on the invoice, and the last one vendors put on the pricing page.

Two lines on the invoice.
Both on the pricing page.

We bill browser hours and traffic beyond your allowance, at $1/GB. An idle session closes itself after 20 minutes instead of billing on.

What 50 GB of residential traffic costs

Plans & Pricing

Every plan runs the same browser, with residential IPs included. Plans differ in browser hours and parallel sessions.

Need more at once? Add parallel sessions to any plan for $2 a month each, as many as you need. Proxy traffic beyond your allowance is $1/GB.

Browser for AI agents FAQ

What is AI agent browser automation?

Using a browser as the hands of an autonomous agent: clicking, typing, uploading and moving between pages, while one browser profile keeps the cookies, the device fingerprint and the residential IP across runs. Every run picks up from the same state.

How long does an agent stay logged in?

As long as the site's own login lasts. The profile comes back with the same cookies, the same device and the same IP, so the session picks up where it left off. What ends a login is the site expiring it, not us.

How long can a single session run?

As long as the job needs. There is no cap on active session time, so a nine-hour run is one session, not a chain of reconnects. A session left idle for 20 minutes closes itself, so you never pay for a browser nobody is driving.

What happens when a step needs a person?

Every session has a live URL. Open it and you are inside the browser your agent is driving, on the same page, in the same session. Finish the step by hand and the run carries on from the next one. The URL comes from the dashboard or the API.

Can I put a live session inside my own product?

Yes. The live session URL can be embedded, so your users drive a signed-in browser without leaving your app, and you do not build a remote browser yourself.

Does it work with LangChain, CrewAI or my own framework?

Yes. Sessions connect over CDP, so anything that drives Playwright or Puppeteer drives a Gologin session with one line changed. Selectors, waits, assertions and CI stay as they are. Rather not write driver code? Use the MCP server or the agent browser CLI.

Can the agent fill forms and upload files?

Yes. The agent browser CLI gives it snapshot, click, type, fill, screenshot, PDF and upload on page references instead of fragile selectors, so the agent says what it wants and gets the element.

What does the MCP server give me?

It turns Gologin profiles, proxies and cloud sessions into tools your assistant calls directly, so Claude or Cursor can create a profile, add a proxy and start a session without you wiring an SDK. The same session sits behind the MCP server, the CLI and a plain CDP connection.

Can I use my own proxies, or mobile IPs?

Yes. Residential IPs come with the session. Mobile IPs from Gologin Proxies attach to a profile in one API call, and your own proxies attach the same way. The session uses whatever the profile carries.

What if a site asks for verification?

Open the live session and complete the step yourself; the agent carries on after you. If you only need the page and not the session, Web Unlocker returns the rendered public page and bills only on success.

When should I use Web Unlocker instead?

When the job needs no account. A one-off fetch of a public page has nothing to stay logged in to, so Web Unlocker takes a URL and returns the rendered page, billed only on success. Use Cloud Browser when the job holds an account: anything that has to be signed in on the second run and the hundredth.

Give your AI agent a browser that stays logged in.

One line connects your agent to a session that keeps its identity: cookies, device fingerprint and residential IP. Build anything that must still be signed in on the hundredth run.

Free to start, no card. Residential IPs included.
