What is a Browser Use Cloud browser?

A Browser Use Cloud browser is a real Chromium browser running on Browser Use's servers. You create one with a single API call, drive it over the Chrome DevTools Protocol (CDP) with Playwright, Puppeteer, Stagehand or the browser-use agent, watch it live, and stop it when you are done. Stealth, CAPTCHA solving, residential proxies, saved logins and recordings are built in, at $0.02 per browser-hour with no subscription.

How a session works

  1. 1

    Create

    POST https://api.browser-use.com/api/v4/browsers with your X-Browser-Use-API-Key, or client.browsers.create() in the Python or TypeScript SDK. Optional fields pick the proxy country, a saved profile, recording, screen size, CAPTCHA solving and a timeout from 1 to 240 minutes (default 60). The response carries id, cdpUrl and liveUrl.
  2. 2

    Connect

    Pass cdpUrl to any CDP client: Playwright's connectOverCDP, Puppeteer's connect, Stagehand v3's localBrowserLaunchOptions.cdpUrl, or the browser-use agent. The same browser can run your script and an agent, one after the other.
  3. 3

    Watch

    Open or embed liveUrl to see the browser and take over a login or a CAPTCHA by hand. With enableRecording, an MP4 is ready once processing finishes after the browser stops, at recordingUrl on GET /api/v4/browsers/{id}. Live preview docs.
  4. 4

    Stop

    client.browsers.stop(id), or PATCH /api/v4/browsers/{id} with {"action":"stop"}. Closing the CDP connection does not stop the browser or its billing; the timeout does, if you forget.

Built for production, with receipts.

SOC 2 Type II, audited for July 17 to October 17, 2025 (report on request). A fresh, isolated browser for every session. Concurrency from 10 to 1,000 browsers per project, rising with what the project has paid, and more on enterprise terms with HIPAA support and zero data retention. On neutral third-party benchmarks a full session lifecycle takes 493 ms median on BrowserArena, October 14, 2026, and scores 95.2 on ComputeSDK. On Stealth Bench V2 it got through on 90.5% of visits to bot-protected sites, the best of every provider tested. The 100 sites were picked because Browser Use Cloud historically got through where stock Chrome with a US proxy did not. They are hard on purpose and not a balanced sample of the web or of anti-bot vendors.

Tradeoffs.

Chromium only, no Firefox or WebKit. Selenium cannot attach, because its debugger_address only accepts a local host and port; use Playwright or Puppeteer. Recordings are MP4 video, off by default, with no DOM replay. One browser runs at most 4 hours. Stagehand v4 needs its own browser extension, so use Stagehand v3. Not the fastest to start: on BrowserArena, Tilion and Kernel create sessions faster.

What is inside every browser

API
https://api.browser-use.com/api/v4: POST /browsers, PATCH /browsers/{id}. SDKs: browser-use-sdk for Python and TypeScript.
Protocol
Chrome DevTools Protocol over WebSocket, from the cdpUrl. Playwright, Puppeteer, Stagehand v3, browser-use or any CDP client.
Live view
A liveUrl for every browser: watch, take over, or embed it in an iframe.
Recording
MP4 with enableRecording, off by default. Ready once processing finishes after the browser stops: poll GET /api/v4/browsers/{id} for recordingUrl.
Profiles
Cookies, localStorage and logins persist across browsers with profileId.
Proxies
Residential in 195+ countries at $5/GB, US by default, picked per browser with proxyCountryCode; customProxy for your own, or none. Direct and bring-your-own-proxy traffic is $0.20/GB.
Stealth and CAPTCHAs
Our own hardened Chromium build, fingerprints randomized per session, automatic CAPTCHA solving on by default. How it works.
Session length
1 to 240 minutes, 60 by default.
Concurrency
10 on a new project, up to 1,000 by total paid, more on enterprise. Usage tiers.
Price
$0.02 per browser-hour, no subscription, credits never expire.

Questions people ask

What is a cloud browser?

A real browser that runs on someone else's servers and that your code or agent controls remotely, usually over the Chrome DevTools Protocol. You get a fresh, isolated browser on demand instead of running and scaling Chrome yourself.

What is a Browser Use Cloud browser?

A Browser Use Cloud browser is a real Chromium browser running on Browser Use's servers. You create one with a single API call, drive it over the Chrome DevTools Protocol (CDP) with Playwright, Puppeteer, Stagehand or the browser-use agent, watch it live, and stop it when you are done. Stealth, CAPTCHA solving, residential proxies, saved logins and recordings are built in, at $0.02 per browser-hour with no subscription.

How is it different from running Playwright on my own machine?

Your script logic stays the same. Create the browser through the API, replace chromium.launch() with chromium.connectOverCDP(cdpUrl), and stop it with client.browsers.stop(id) in a finally block: browser.close() only disconnects and does not stop billing. The browser runs on our servers with a hardened Chromium build, residential proxies and CAPTCHA solving, so it gets into sites that block a stock headless Chrome, and you can run many at once without managing machines.

Does it work with Stagehand?

Stagehand v3 connects with env "LOCAL" and localBrowserLaunchOptions.cdpUrl set to the browser's cdpUrl. Stagehand v4's localBrowser.connect() looks for its own browser extension and failed to connect in our test of 4.2.1, so use v3, or Playwright directly. Stagehand's server-side caching and Model Gateway only run on Browserbase.

Can I watch or take over the browser?

Yes. Every browser returns a liveUrl on live.browser-use.com. Open it in a tab or embed it in an iframe; anyone with the URL can click and type in the live browser, so treat it as a credential. Set enableRecording for an MP4: it is ready once processing finishes after the browser stops, at recordingUrl on GET /api/v4/browsers/{id}.

How many can I run at once, and what does it cost?

$0.02 per browser-hour, plus $5/GB for residential proxy traffic or $0.20/GB for direct or bring-your-own-proxy traffic, with no subscription. A new project runs 10 browsers at once; the limit rises with the total the project has paid, up to 1,000, and beyond on enterprise terms. Eligible new signups get a one-time $1 credit.
