BROWSER USE

- Browser Use Agents: give Browser Use a task and receive completed work. API V4 is current for new integrations.
- Browser Infrastructure: connect your agent or automation to managed browsers through SDK, REST, or CDP. Starts at $0.02/browser-hour.
- Developer tools: Open Source, Browser Harness, SDK, and MCP support the two products above.

# Anti-detect browser for automation and scraping

> Our own hardened Chromium fork with per-session fingerprints, automatic CAPTCHA solving and residential proxies in 195+ countries, reachable over CDP for $0.02 per browser-hour. 81% of 71 Cloudflare, Akamai, PerimeterX and DataDome sites reached; next provider 77%; plain headless Chromium 2%.

## Three layers, in the order they act

1. Fingerprint. The Chromium build randomizes canvas, WebGL, fonts and navigator per session and removes headless signals. It is maintained and patched non-stop.
2. Network. Residential proxies matched to the site's country, per session, at $5/GB (`proxyCountryCode`). Or bring your own proxy with `customProxy` (host, port, username, password); egress is then $0.20/GB.
3. Challenge. If a CAPTCHA still renders, the browser solves it in place. If a site blocks the whole browser, switch proxy country or hand the session to a person through the live view.

## Stealth benchmark, 71 protected sites

| Provider | Sites reached |
|---|---:|
| Browser Use Cloud | 81% |
| Anchor | 77% |
| kernel | 67% |
| Steel | 47% |
| Browserbase | 42% |
| Hyperbrowser | 40% |
| Headful Chromium | 50% |
| Headless Chromium | 2% |

Sites were chosen from 300,000 real security-check events in production traffic. Per vendor: Cloudflare 93%, Akamai 85%, PerimeterX 81%. [Methodology](https://browser-use.com/posts/stealth-benchmark)

## Use it from Playwright or Puppeteer

Create a browser with `POST /api/v4/browsers`, connect to the returned `cdpUrl` with `connectOverCDP` or `puppeteer.connect`. Stealth is on; there is no flag to set. [Remote browser for Playwright](https://browser-use.com/playwright.md)
