See how we perform in the hardest stealth benchmark.

​
What’s included

Every cloud browser session runs in a hardened Chromium fork with stealth enabled by default — no configuration needed.
  • Anti-detect browser fingerprinting — Canvas, WebGL, fonts, navigator, and other browser fingerprints are randomized per session to appear as a real user. Fingerprint test results vary with browser version and the target site.
  • Ad and cookie banner blocking — Banners are dismissed automatically so the agent sees clean pages and executes faster.
  • Anti-bot protections — Help with sites protected by Cloudflare, PerimeterX, and other detection services. Access to every site is not guaranteed.
Cloud browsers also solve CAPTCHAs automatically. See CAPTCHA handling for what to do when a solver is still working or a site has a specific anti-bot issue.

​
Residential proxies

Residential proxies are enabled by default across 195+ countries. This makes browser sessions appear as real users from the target geography. See Proxies for details on geo-targeting and custom proxy configuration. Stealth is included in the managed browser. It is not a separate subscription upgrade you must buy to enable these protections. A target site can still reject a browser or require verification; see troubleshooting.

​
Window resizing

The browser window size is fixed by default, because resizing makes a browser easier to detect. To let your code or the agent resize it over CDP, set allowResizing: true when you create a browser, or browserSettings.allowResizing on a V4 run. On a run, the setting applies only when the run starts a new browser, and follow-up runs inherit it.
