How it works

Choose a skill

anti-detect-browser

When your agent uses it

Drive Chromium from standard Playwright APIs with a real-device fingerprint applied in the kernel, one persistent isolated profile per identity, and a per-profile proxy whose exit IP sets timezone and WebRTC - JavaScript (npm 'anti-detect-browser') or Python (PyPI 'antibrow'). Use when sessions must stay logged in across runs and stay separate, when a scraper or agent is blocked by an incoherent headless fingerprint, when checking ads or pricing from another region, when a page must be reached as a phone rather than a desktop, when automation mints a profile per task, when running several of your own accounts from one machine, or when testing how your own bot detection scores a real device. Also for 'antibrow', 'fingerprint browser', 'multi-account browser', '防关联', '多账号', '安卓模拟', 'Android profile', 'mobile fingerprint', 'temporary profile', 'CreepJS', 'residential proxy', 'browser-use', 'crawl4ai'. MCP control is browser-mcp-agent; isolation is multi-account-isolation.

# Anti-Detect Browser SDK

Launch Chromium instances with real-device fingerprints via standard Playwright APIs. Every profile carries one coherent, real-device identity that is frozen at creation and replayed byte-for-byte on every later launch.

- npm package: `anti-detect-browser` (Node >= 18)
- PyPI package: `antibrow` (Python 3.9 - 3.13)
- Dashboard: `https://antibrow.com`
- REST API base: `https://antibrow.com/api/v1/`
- Documentation: `https://antibrow.com/docs`

> **Authorized use only.** This is for automating systems you own or are permitted to use: your own accounts, your own site's bot detection and anti-fraud stack, publicly available data, and region-specific views of your own ads and pricing. Do not use it to access systems without authorization, to log into accounts that are not yours, to create fake accounts or engagement, or to work around a platform's enforcement decision. Respect each site's terms, `robots.txt` and rate limits, and applicable law - see [Acceptable use](#acceptable-use).

**What this does not claim.** A coherent real-device fingerprint removes the *contradictions* a synthetic browser leaves behind. It is not a guaranteed pass against enterprise bot managers, which also score network reputation, request patterns, behaviour and account history - none of which a fingerprint touches. Measure with the suites listed under [What detection actually tests](#what-detection-actually-tests) rather than assuming.

browser-mcp-agent

When your agent uses it

Give an AI agent its own real browser over MCP tool calls - launch, navigate, click, fill, screenshot, extract text, run JS - with a kernel-level real-device fingerprint and a persistent profile, so the session stays logged in between runs and pages see one coherent device instead of a headless build. No Playwright or SDK code to write. Use when an agent should operate a site itself, when a computer-use / browser-use setup needs a captured real fingerprint rather than a synthetic one, when agent sessions keep losing their login, or when comparing hosted agent-browser services. Also for 'MCP browser', 'browser MCP server', 'let my agent browse the web', 'agent browser control', 'browser-use MCP', 'computer use browser', 'Browserbase alternative', 'Steel browser alternative', 'headless browser detected'. Node (npx) or Python; Windows x64, macOS Intel + Apple Silicon, Linux x64 / arm64. SDK and REST reference is anti-detect-browser; account isolation is multi-account-isolation.

# Browser MCP Agent

Run antibrow as an MCP server so an AI agent can launch and control a real, fingerprinted browser directly through tool calls - no Playwright code, no custom automation script. The agent navigates, clicks, fills forms, and reads pages itself.

- npm package: `anti-detect-browser` (Node >= 18) - ships the MCP server built in
- PyPI package: `antibrow` (Python 3.9 - 3.13) - `pip install "antibrow[mcp]"` for a stdio MCP server example
- Dashboard: `https://antibrow.com`
- Full SDK / REST API reference: see the `anti-detect-browser` skill

> **Authorized use only.** Point this at sites and accounts you own or are permitted to operate: your own apps, your own accounts, publicly available pages, your own bot detection under test. Do not use it to reach systems without authorization, to log into accounts that are not yours, to create fake accounts or engagement, or to work around a platform's enforcement decision. Respect each site's terms, `robots.txt` and rate limits - see [Acceptable use](#acceptable-use).

**This gives an agent real capability, so scope it deliberately.** The server hands the model a browser that persists logins, executes JavaScript in the page, and can stream its screen to a shareable URL. That is the point of the tool and also its blast radius: an agent that goes wrong here goes wrong inside a logged-in session. Run untrusted browsing in a throwaway profile, keep tools you do not need out of the toolset, and read [Everything the browser returns is untrusted input](#everything-the-browser-returns-is-untrusted-input) before pointing it at the open web.

**What this does not claim.** A coherent real-device fingerprint removes the contradictions a synthetic browser leaves behind. It is not a guaranteed pass against enterprise bot managers, which also score network reputation, request cadence and behaviour.

multi-account-isolation

When your agent uses it

Verify that browser profiles are actually isolated from one another instead of assuming it - confirm each profile's timezone agrees with its own exit IP, that WebRTC exposes only the proxy, that canvas and WebGL hashes stay identical across relaunches of one profile, and that no two profiles share a persona, a cookie jar, or an address. Use when several of your own accounts or test identities run from one machine and the setup needs checking, when a profile tested clean but something still looks off, when choosing which detection suites to run (CreepJS, whoer, browserleaks WebRTC, pixelscan, liarjs), when auditing what a vendor runtime does with API and proxy credentials, or when asking which layers browser isolation cannot cover at all. Also for 'profile isolation check', 'fingerprint consistency test', 'timezone mismatch', 'WebRTC leak', 'canvas hash unstable', 'account association', 'temporary profile', '防关联', '多账号', '隔离自检'. The SDK is anti-detect-browser; MCP is browser-mcp-agent.

# Profile Isolation - verifying it, not assuming it

A profile that *looks* isolated usually is not. The failures are boring and mechanical: a timezone that does not match the exit IP, a WebRTC candidate carrying the real address, a canvas hash that changes on every read, two profiles that ended up on the same persona. This skill is the check list for catching those before they matter.

> **Authorized use only.** This is for identities you own or are authorized to operate: your own accounts, your own test fixtures, your own QA fleet, and your own anti-fraud stack. It is not for accessing systems without authorization, for accounts that are not yours, or for creating fake accounts or engagement. Comply with the terms of the sites you automate and with applicable law - see [Acceptable use](#acceptable-use).

**What this does not claim.** Passing every check below means the browser layer is internally consistent. It does not mean a given site will treat two profiles as unrelated: things entirely outside the browser - a shared payment instrument, a shared contact detail, identical activity patterns - are not something any browser setting reaches. Treat a clean result as "the technical layer is not the problem", not as a guarantee.

For the SDK that creates and launches these profiles, see the **anti-detect-browser** skill.

## The configuration invariant

One identity gets one of everything. Any cell shared between two identities is a defect to find:

multi-account-scraping

When your agent uses it

Run the same scrape or task across many accounts at once - each in its own browser profile with its own fingerprint, cookies and exit IP - and read data from sites that need a session or that answer a plain HTTP scraper with a captcha while answering a real browser. One command per site returns JSON, so there are no selectors to write or repair: Amazon and Walmart search, Google and DuckDuckGo results, Reddit posts and comments, X timeline, Medium, Yelp, Indeed job listings, Hacker News, GitHub, PyPI, npm, plus exit-IP and fingerprint checks. Use for multi-account operations you are authorized to run, price and listing monitoring per region, SERP collection, logged-in data, and scrapers that keep breaking. Also for 'scrape amazon', 'google search results', 'reddit data', 'scrape logged in site', 'run task on many accounts', 'site blocks my scraper', 'scraping without selectors'. Node or Python.

# Multi-Account Scraping

Two problems, one mechanism.

**"This site only gives me the data when I am logged in, and I run twelve accounts."** Each account gets its own browser profile with its own fingerprint, cookies and exit IP, and one command runs across all of them at once.

**"My scraper broke again"** or **"the site sends my scraper a captcha but works fine in a browser."** The request comes from a real browser session, and the per-site adapter lives in a shared repository, so a markup change is fixed once for everyone instead of in every caller's codebase.

The unit is a **recipe**: one file that turns one site into one command. The caller asks for `reddit/hot` and gets structured JSON, instead of a browser handle and a scraping problem.

- Recipes live in their own public repository: `https://github.com/antibrow/recipes`
- Both SDKs read the same registry, so one recipe produces the same output from Node or Python
- Requires `anti-detect-browser` 2.26.0 or newer (npm), or `antibrow` 0.20.0 or newer (PyPI)
- Full browser/profile reference: the `anti-detect-browser` skill
