Anti Detect Browser

# Anti-Detect Browser SDK

Launch Chromium instances with real-device fingerprints via standard Playwright APIs. Each browser gets a unique, consistent digital identity - undetectable by anti-bot systems.

- npm package: `anti-detect-browser`
- Dashboard: `https://antibrow.com`
- REST API base: `https://antibrow.com/api/v1/`
- Documentation: `https://antibrow.com/docs`

## When to use

- **Multi-account management** - Run dozens of social media, e-commerce, or ad accounts on the same machine without linking. Each browser profile has its own fingerprint, cookies, and storage.
- **Web scraping & data collection** - Rotate fingerprints across scraping sessions to avoid detection and fingerprint-IP correlation bans.
- **Ad verification & competitive intelligence** - View ads and content as different user profiles across regions and device types.
- **Social media automation** - Manage multiple accounts with persistent profiles that survive browser restarts.
- **E-commerce operations** - Operate multiple seller/buyer accounts with fully isolated browser environments.
- **AI agent browser control** - Run as an MCP server so AI agents (Claude, GPT, etc.) can launch, navigate, and interact with anti-detect browsers through tool calls.
- **QA & cross-environment testing** - Test how your site behaves under different browser fingerprints, screen sizes, and device configurations.

## Quick start

```bash
npm install anti-detect-browser
```

```typescript
import { AntiDetectBrowser } from 'anti-detect-browser'

// Get your API key at https://antibrow.com
const ab = new AntiDetectBrowser({ key: 'your-api-key' })

const { browser, page } = await ab.launch({
  fingerprint: { tags: ['Windows 10', 'Chrome'] },
  profile: 'my-account-01',
  proxy: 'http://user:pass@host:port',
})

// Standard Playwright API from here — zero learning curve
await page.goto('https://example.com')
await browser.close()
```

## Core concepts

### Profiles — persistent browser identities

A profile saves cookies, localStorage, and session data across launches. Same profile name = same stored state next time.

```typescript
// First launch — fresh session
const { page } = await ab.launch({ profile: 'shop-01' })
await page.goto('https://shop.example.com/login')
// ... login ...
await browser.close()

// Later — session restored, already logged in
const { page: p2 } = await ab.launch({ profile: 'shop-01' })
await p2.goto('https://shop.example.com/dashboard') // no login needed
```

### Fingerprints — real device data from the cloud

Each launch fetches a real fingerprint collected from actual devices. Over 30 categories (Canvas, WebGL, Audio, Fonts, WebRTC, WebGPU, etc.) with 500+ individual parameters.

```typescript
// Windows Chrome, version 130+
await ab.launch({
  fingerprint: { tags: ['Windows 10', 'Chrome'], minBrowserVersion: 130 },
})

// Mac Safari
await ab.launch({
  fingerprint: { tags: ['Apple Mac', 'Safari'] },
})

// Mobile Android
await ab.launch({
  fingerprint: { tags: ['Android', 'Mobile', 'Chrome'] },
})
```

Available filter tags: `Microsoft Windows`, `Apple Mac`, `Android`, `Linux`, `iPad`, `iPhone`, `Edge`, `Chrome`, `Safari`, `Firefox`, `Desktop`, `Mobile`, `Windows 7`, `Windows 8`, `Windows 10`

### Visual identification — tell windows apart at a glance

When running many browsers simultaneously, each window gets a floating label, title prefix, and unique theme color.

```typescript
await ab.launch({
  profile: 'twitter-main',
  label: '
