Browsers

What are Browsers?

Browsers give your AI agents the ability to interact with the web just like a human user. Each browser session is a managed Chromium instance powered by Browserbase, running in the cloud with stealth mode and anti-detection built in.

Key Features

• Managed Chromium — No infrastructure to maintain, always up-to-date
• Stealth mode — Anti-detection fingerprinting to avoid bot blockers
• Full page interaction — Navigate, click, type, scroll, wait
• Screenshots — Capture full-page or element-level screenshots
• Data extraction — Extract text, structured data, or DOM elements
• Session persistence — Maintain cookies and state across navigations
• Concurrent sessions — Run multiple browser sessions in parallel

When to Use Browsers

How It Works

Your Agent
    |
    v
tx.browsers.create()
    |
    v
+---------------------------+
|  Browserbase Chromium      |
|  - Stealth fingerprinting |
|  - Session cookies         |
|  - Network interception    |
|  - Screenshot capture      |
+---------------------------+
    |
    v
tx.browsers.navigate(id, { url: '...' })
tx.browsers.click(id, { selector: '...' })
tx.browsers.screenshot(id)
    |
    v
tx.browsers.close(id)

1. Create — A Chromium instance launches in the cloud
2. Interact — Navigate, click, type, scroll, and extract data
3. Close — The session is destroyed and resources are released

Anti-Detection

Browserbase sessions include stealth mode by default:

• Realistic fingerprints — User agent, viewport, WebGL, and Canvas fingerprints match real browsers
• Human-like behavior — Configurable mouse movement and typing delays
• Proxy support — Route traffic through residential proxies to avoid IP-based blocking
• Cookie persistence — Maintain session state across navigations

Session Limits
