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

npm install anti-detect-browser

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.

// 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.

// 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.

await ab.launch({
  profile: 'twitter-main',
  label: '@myhandle',       // floating label + window title
  color: '#e74c3c',         // unique window border color
})

Proxy integration

Route each browser through a different proxy for geo-targeting or IP rotation.

await ab.launch({
  proxy: 'socks5://user:pass@us-proxy.example.com:1080',
  fingerprint: { tags: ['Windows 10', 'Chrome'] },
  profile: 'us-account',
})

Live View — watch headless browsers in real time

Monitor headless sessions from the https://antibrow.com dashboard. Useful for debugging AI agent actions or letting team members observe.

const { liveView } = await ab.launch({
  headless: true,
  liveView: true,
})

console.log('Watch live:', liveView.viewUrl)
// Share this URL — anyone with access can see the browser screen

Inject into existing Playwright setup

Already have Playwright scripts? Add fingerprints without changing your workflow.

import { chromium } from 'playwright'
import { applyFingerprint } from 'anti-detect-browser'

const browser = await chromium.launch()
const context = await browser.newContext()

await applyFingerprint(context, {
  key: 'your-api-key',
  fingerprint: { tags: ['Windows 10', 'Chrome'] },
  profile: 'my-profile',
})

const page = await context.newPage()
await page.goto('https://example.com')

MCP server mode — for AI agents

Run as an MCP server so AI agents can launch and control fingerprint browsers via tool calls.

{
  "mcpServers": {
    "anti-detect-browser": {
      "command": "npx",
      "args": ["anti-detect-browser", "--mcp"],
      "env": { "ANTI_DETECT_BROWSER_KEY": "your-api-key" }
    }
  }
}

Workflow examples

Multi-account social media

const accounts = [
  { profile: 'twitter-1', label: '@brand_main', color: '#1DA1F2' },
  { profile: 'twitter-2', label: '@support', color: '#FF6B35' },
  { profile: 'twitter-3', label: '@personal', color: '#6C5CE7' },
]

for (const acct of accounts) {
  const { page } = await ab.launch({
    fingerprint: { tags: ['Windows 10', 'Chrome'] },
    proxy: getNextProxy(),
    ...acct,
  })
  await page.goto('https://twitter.com')
}

Scraping with fingerprint rotation

for (const url of urlsToScrape) {
  const { browser, page } = await ab.launch({
    fingerprint: { tags: ['Desktop', 'Chrome'], minBrowserVersion: 125 },
    proxy: rotateProxy(),
  })
  await page.goto(url)
  const data = await page.evaluate(() => document.body.innerText)
  saveData(url, data)
  await browser.close()
}

Headless monitoring with live view

const { page, liveView } = await ab.launch({
  headless: true,
  liveView: true,
  profile: 'price-monitor',
  fingerprint: { tags: ['Windows 10', 'Chrome'] },
})

// Share the live view URL with your team
console.log('Dashboard:', liveView.viewUrl)

while (true) {
  await page.goto('https://shop.example.com/product/123')
  const price = await page.textContent('.price')
  if (parseFloat(price) < targetPrice) notify(price)
  await page.waitForTimeout(60_000)
}

REST API

Base URL: https://antibrow.com/api/v1/ — all endpoints require Authorization: Bearer <api-key> header.

Fingerprints

Method Endpoint Description

GET /fingerprints/fetch Fetch a fingerprint matching filter criteria. Returns { dataUrl } — download the presigned URL for full fingerprint data.

GET /fingerprints/versions List available browser versions

Query parameters for /fingerprints/fetch: tags, id, minBrowserVersion, maxBrowserVersion, minWidth, maxWidth, minHeight, maxHeight

Profiles

Method Endpoint Description

GET /profiles List all profiles

POST /profiles Create a new profile (server assigns a random fingerprint). Returns profile info including dataUrl for immediate fingerprint data download.

GET /profiles/:name Get profile details with dataUrl for fingerprint data download

DELETE /profiles/:name Delete a profile

POST /profiles request body:

{ "name": "my-profile", "tags": ["Windows 10", "Chrome"] }

POST /profiles response (201):

{
  "name": "my-profile",
  "tags": ["Windows 10", "Chrome"],
  "ua": "Mozilla/5.0 ...",
  "browserVersion": 131,
  "width": 1920,
