Extra Stealth is available on our Growth tier.Upgrade Now
Anchor Browser provides built-in stealth capabilities that help avoid detection by anti-bot systems and website fingerprinting. These features enable automated browsing that mimics human behavior and bypasses common detection mechanisms.

​
What is Extra Stealth Mode?

Extra Stealth Mode leverages a specialized Chrome browser environment that provides:
  • 🔒 Advanced Anti-Detection - Bypass sophisticated bot detection systems and CAPTCHAs
  • 🛡️ Automation Consistency - Maintain consistent access without getting blocked
  • 👤 Human-Like Behavior - Mimic real user patterns to avoid suspicion
Alternative Cloudflare-verified access to webpages is available through our Cloudflare Web Bot Auth Integration.

​
Quick start - Enable stealth features

1

Create a session with extra stealth enabled

Create a browser session with extra stealth features enabled using the SDK:
Extra stealth mode requires proxy configuration to be active. If proxy is disabled, extra stealth will be automatically disabled by the system.Read more about Proxy Configuration
import Anchorbrowser from "anchorbrowser";

const anchorClient = new Anchorbrowser()
const session = await anchorClient.sessions.create({
    browser: {
        extra_stealth: {
            active: true
        }
    },
    session: {
        proxy: {
            active: true
        }
    }
});

console.log(session);
2

Use the session for automated browsing

Once your stealth session is created, you can use it for automated browsing that bypasses common detection mechanisms:
import Anchorbrowser from "anchorbrowser";

const anchorClient = new Anchorbrowser()
 
// Create stealth session
const session = await anchorClient.sessions.create({
    browser: {
        extra_stealth: {
            active: true
        }
    },
    session: {
        proxy: {
            active: true
        }
    }
 })

// Use the session for automated tasks
const result = await anchorClient.agent.task(
    "Navigate to a website and check if I'm detected as a bot",
    {
        sessionId: session.data.id
    }
);

console.log(result);

Usage with Profiles

Use stealth mode with saved browser profiles for persistent authenticated sessions: 
import Anchorbrowser from "anchorbrowser";

const anchorClient = new Anchorbrowser()
const session = await anchorClient.sessions.create({
    browser: {
        extra_stealth: {
            active: true
        },
        profile: {
            name: 'stealth-profile',
            persist: true   // Only on Profile Creation
        }
    },
    session: {
        proxy: {
            active: true
        }
    }
})
console.log(session)
