Releases are avaliable, but may not be suitable for production use. [#](https://camoufox.com/#features) Features -------------------------------------------- * **Invisible to all anti-bot systems** 🎭 * Camoufox performs better than most commercial anti-bot browsers. * **Fingerprint injection & rotation (without JS injection!)** * All navigator properties (device, OS, hardware, browser, etc.) ✅ * Screen size, resolution, window, & viewport properties ✅ * Geolocation, timezone, locale, & Intl spoofing ✅ * WebRTC IP spoofing at the protocol level ✅ * Voices, speech playback rate, etc. ✅ * And much, much more! * **Anti Graphical fingerprinting** * Canvas anti-fingerprinting ✅ * WebGL parameters, supported extensions, context attributes, & shader precision formats ✅ * Font spoofing & anti-fingerprinting ✅ * **Quality of life features** * Human-like mouse movement 🖱️ * Blocks & circumvents ads 🛡️ * No CSS animations 💨 * Debloated & optimized for memory efficiency ⚡ * [PyPi package](https://pypi.org/project/camoufox/) for updates & auto fingerprint injection 📦 * Stays up to date with the latest Firefox version 🕓 Get started python/ [](https://camoufox.com/python/) * * * [#](https://camoufox.com/#design-and-implementation) Design and Implementation ------------------------------------------------------------------------------ The goal of Camoufox is to provide a robust, undetectable anti-fingerprinting solution that blends in with regular user traffic. 1\. Fingerprinting Protection [](https://camoufox.com/#1-fingerprinting-protection) Privacy-focused browsers and add-ons often become counterproductive by making users more identifiable through detectable modifications or JavaScript inspection. This, ironically, makes the user stand out by creating unique fingerprints, making them more susceptible to be tracked or flagged by anti-bot systems. Camoufox solves this by operating at a lower level, using fingerprint rotation and crowdblending techniques by modifying device information in the C++ implementation instead of injecting JavaScript, which leaves a trail. Built on Firefox and research from the Tor project, LibreWolf, and Arkenfox, Camoufox aims to avoid common user identification methods to provide a robust, undetectable anti-fingerprinting. 2\. Crowdblending [](https://camoufox.com/#2-crowdblending) A design goal of Camoufox is to blend in with real world traffic. It must behave like a normal user and avoid all statistical fingerprinting, meaning there should _not_ be thousands of requests using the same device information on a large scale. To achieve this, Camoufox uses [BrowserForge](https://github.com/daijro/browserforge) to rotate device information such as the screen, OS, and hardware to mimic the statistical distribution of device characteristics in real-world traffic. Additionally, Camoufox uses a natural mouse movement algorithm to behave like a normal user. 3\. Stealth [](https://camoufox.com/#3-stealth) Finally, Camoufox should avoid all bot detection, of any kind, by any means. It should not inject any JavaScript into the page or manipulate the DOM in any way. In Camoufox, all of Playwright's internal Page Agent Javascript is sandboxed and isolated from the main world. This makes it **impossible** for a page to detect the presence of Playwright/Juggler. In addition, data is intercepted at the C++ implementation level, making the changes undetectable through JavaScript inspection. Why Firefox and not Chromium? [](https://camoufox.com/#why-firefox-and-not-chromium) Camoufox is built on top of Firefox instead of Chromium for these main reasons: 1. Chrome is bundled with certain features that Chromium does not have. Anti-bot providers can detect if you are using Chromium rather than Chrome. Since Chrome is closed source, patching Chrome is significantly more difficult. 2. CDP is more widely used and known, so it's a more common target for bot detection 3. Juggler operates on a lower level than CDP, making it less prone to JS leaks. 4. Firefox is more ideal for fingerprint rotation. More research has been made on Firefox for fingerprinting resistance than on Chromium. Is Camoufox open source? [](https://camoufox.com/#is-camoufox-open-source) **Almost all** of Camoufox's code is publicly avaliable on GitHub. However, certain features like the [Canvas fingerprint rotation](https://camoufox.com/fingerprint/canvas/) patch are closed source to prevent anti-bot providers from reverse engineering Camoufox. If you'd like to build Camoufox without the closed source features, please refer to the [build guide](https://camoufox.com/development/buildcli/) . What's planned? [](https://camoufox.com/#whats-planned) * Continue research on potential leaks * AI powered selector location * Remote hosting Camoufox as a Playwright server Contents * [Features](https://camoufox.com/#features) * [Design and Implementation](https://camoufox.com/#design-and-implementation) Important Notice ---------------- Hello! In March 2025, I had a medical emergency and have been hospitalized since. I haven't been able to continue my work for some time. I was previously updating Camoufox daily, and plan to return to that schedule as soon as I'm able. My goal is to have Camoufox back to its usual performance and be fully caught up by the end of 2025. Thank you for your patience and understanding. Ok! --- # Stealth Performance | Camoufox [#](https://camoufox.com/stealth/#stealth-performance) Stealth Performance ========================================================================== In Camoufox, all of Playwright's internal Page Agent Javascript is sandboxed and isolated.

This makes it impossible for the page to detect JavaScript reading the DOM: >>> page.goto("https://example.com/") >>> page.evaluate("document.querySelector('h1').innerText") 'Example Domain' However, your JavaScript will **not** be able to modify the DOM: >>> page.evaluate("document.querySelector('h1').remove()") # Will not work! * * * ### # Modifying the DOM - Main World To be able to modify the DOM, run JavaScript in the **main world**—the non-isolated scope. ##### Leak Warning All code executed in the main world can be detected by the target website. Only execute JavaScript in the main world if absolutely necessary. * * * To enable main world execution, set the `main_world_eval` parameter to `True`: with Camoufox(main_world_eval=True) as browser: page = browser.new_page() page.goto("https://example.com/") Now, you can inject JavaScript in the main world by prefixing the code with `mw:` >>> page.evaluate("mw:document.querySelector('h1').remove()") # h1 is now removed! You can also return JSON serializable data from the main world: >>> page.evaluate("mw:{key: 'value'}") {'key': 'value'} ##### Note Returning references to nodes/elements from the main world is not supported, since Playwright's utilities do not run in the main world. To retrieve node references, use the isolated world instead. --- # Remote Server | Camoufox # Remote Server =============== ##### Warning Warning! This feature is experimental. It uses a hacky workaround to gain access to undocumented Playwright methods. Camoufox can be ran as a remote websocket server. It can be accessed from other devices, and languages other than Python supporting the Playwright API. * * * # Launching ----------- To launch a remote server, run the following CLI command: python -m camoufox server Or, configure the server with a launch script: from camoufox.server import launch_server launch_server( headless=True, geoip=True, proxy={ 'server': 'http://example.com:8080', 'username': 'username', 'password': 'password' }, port=1234, ws_path='hello' ) The server's port and URL path will be defined using the `port` and `ws_path` parameters, or will be random if not defined. Websocket endpoint: ws://localhost:1234/hello All of the following parameters are also supported: See parameters list ../usage/#parameters-list [](https://camoufox.com/python/usage/#parameters-list) * * * # Connecting ------------ To connect to the remote server, use Playwright's `connect` method: from playwright.sync_api import sync_playwright with sync_playwright() as p: # Example endpoint browser = p.firefox.connect('ws://localhost:1234/hello') page = browser.new_page() ... ##### Note Because servers only use **one browser instance**, fingerprints will not rotate between sessions. If you plan on using Camoufox at scale, consider rotating the server between sessions. --- # Virtual Display | Camoufox # Virtual Display ================= While Camoufox includes patches to prevent headless detection, running in headless mode may still be detectable in the future. It's recommended to use a virtual display buffer to run Camoufox headlessly. If you are running Linux, and would like to run Camoufox headlessly in a virtual display, install `xvfb`: sudo apt-get install xvfb sudo pacman -S xorg-server-xvfb #### # Confirm `Xvfb` is installed: $ which Xvfb /usr/bin/Xvfb * * * # Usage ------- Passing `headless="virtual"` will spawn a new lightweight virtual display in the background for Camoufox to run in. from camoufox.sync_api import Camoufox with Camoufox( headless="virtual" ) as browser: page = browser.new_page() page.goto("https://example.com") from camoufox.async_api import AsyncCamoufox async with AsyncCamoufox( headless="virtual" ) as browser: page = await browser.new_page() await page.goto("https://example.com") --- # Passing Config | Camoufox # Passing Config ================ If needed, Camoufox [config data](https://github.com/daijro/camoufox?tab=readme-ov-file#fingerprint-injection) can be overridden/passed as a dictionary to the `config` parameter. This can be used to enable features that have not yet been implemented into the Python library. * * * ##### Warning This isn't recommended, as Camoufox will populate this data for you automatically. See the [parameters list](https://camoufox.com/python/usage/#parameters-list) for more proper usage. from camoufox.sync_api import Camoufox with Camoufox( config={ 'webrtc:ipv4': '123.45.67.89', 'webrtc:ipv6': 'e791:d37a:88f6:48d1:2cad:2667:4582:1d6d', } ) as browser: page = browser.new_page() page.goto("https://www.browserscan.net/webrtc") Camoufox will warn you if you are manually setting properties that the Python library handles internally. --- # BrowserForge Integration | Camoufox # BrowserForge Integration ========================== Camoufox is compatible with [BrowserForge](https://github.com/daijro/browserforge) fingerprints. By default, Camoufox will generate an use a random BrowserForge fingerprint based on the target `os` & `screen` constraints. from camoufox.sync_api import Camoufox from browserforge.fingerprints import Screen with Camoufox( os=('windows', 'macos', 'linux'), screen=Screen(max_width=1920, max_height=1080), ) as browser: page = browser.new_page() page.goto("https://example.com/") If Camoufox is being ran in headful mode, the max screen size will be generated based on your monitor's dimensions unless otherwise specified. ##### Note To prevent UA mismatch detection, Camoufox only generates fingerprints with the same browser version as the current Camoufox version by default. If rotating the Firefox version is absolutely necessary, it would be more advisable to rotate between older versions of Camoufox instead. * * * ##### Warning It is recommended to pass `os` & `screen` constraints into Camoufox instead. Camoufox will handle fingerprint generation for you. This will be deprecated in the future. You can also inject your own Firefox BrowserForge fingerprint into Camoufox. from camoufox.sync_api import Camoufox from browserforge.fingerprints import FingerprintGenerator fg = FingerprintGenerator(browser='firefox') # Launch Camoufox with a random Firefox fingerprint with Camoufox(fingerprint=fg.generate()) as browser: page = browser.new_page() page.goto("https://example.com/") **Note:** As of now, some properties from BrowserForge fingerprints will not be passed to Camoufox. This is due to the outdated fingerprint dataset from Apify's fingerprint-suite (see [here](https://github.com/apify/fingerprint-suite/discussions/308) ). Properties will be re-enabled as soon as an updated dataset is available. --- # Navigator | Camoufox # Navigator =========== Navigator properties can be fully spoofed to other Firefox fingerprints, and it is **completely safe**! * * * # Properties ------------ | Property | Type | Description | | --- | --- | --- | | `navigator.userAgent` | str | Browser and system information | | `navigator.doNotTrack` | str | User's tracking preference | | `navigator.appCodeName` | str | Browser's code name | | `navigator.appName` | str | Browser's name | | `navigator.appVersion` | str | Browser's version | | `navigator.oscpu` | str | Operating system and CPU information | | `navigator.language` | str | Preferred language of the user | | `navigator.languages` | array | User's preferred languages | | `navigator.platform` | str | Platform the browser is running on | | `navigator.hardwareConcurrency` | uint | Number of logical processors | | `navigator.product` | str | Product name of the browser | | `navigator.productSub` | str | Build number of the browser | | `navigator.maxTouchPoints` | uint | Maximum number of simultaneous touch contact points | | `navigator.cookieEnabled` | bool | Whether cookies are enabled | | `navigator.globalPrivacyControl` | bool | User's global privacy control preference | | `navigator.buildID` | str | Build identifier of the browser | | `navigator.onLine` | bool | Whether the browser is online | * * * ##### Note * **navigator.webdriver** is set to false at all times. * `navigator.language` & `navigator.languages` will fall back to the `locale:language`/`locale:region` values if not set. * When spoofing Chrome fingerprints, the following may leak: * navigator.userAgentData missing. * navigator.deviceMemory missing. * Changing the presented Firefox version can be detected by some testing websites, but typically will not flag production WAFs. --- # Cursor Movement | Camoufox # Cursor Movement ================= # Human-like Cursor movement ---------------------------- Camoufox has built-in support for human-like cursor movement. The natural motion algorithm was originally from [rifosnake's HumanCursor](https://github.com/riflosnake/HumanCursor) , but has been rewritten in C++ and modified for more distance-aware trajectories. * * * # Properties ------------ | Property | Type | Description | | --- | --- | --- | | `humanize` | bool | Enable/disable human-like cursor movement. Defaults to False. | | `humanize:maxTime` | double | Maximum time in seconds for the cursor movement. Defaults to `1.5`. | | `humanize:minTime` | double | Minimum time in seconds for the cursor movement. | | `showcursor` | bool | Toggles the cursor highlighter. Defaults to True. | ##### Note The cursor highlighter is **not** ran in the page context. It will not be visible to the page. You don't have to worry about it leaking. * * * # Demo ------ Here is a demo of the cursor highlighter. The testing page for this can be found [here](https://camoufox.com/tests/buttonclick) . --- # Screen | Camoufox # Screen ======== #### # Spoof the screen size, pixel depth, and position of the window. * * * # Properties ------------ | Property | Type | Description | | --- | --- | --- | | `screen.availHeight` | uint | Available height of the screen | | `screen.availWidth` | uint | Available width of the screen | | `screen.availTop` | uint | Y-coordinate of the top of the available area | | `screen.availLeft` | uint | X-coordinate of the left of the available area | | `screen.height` | uint | Total height of the screen | | `screen.width` | uint | Total width of the screen | | `screen.colorDepth` | uint | Color depth of the screen | | `screen.pixelDepth` | uint | Pixel depth of the screen | | `screen.pageXOffset` | double | Horizontal scroll position | | `screen.pageYOffset` | double | Vertical scroll position | * * * ##### Note `screen.colorDepth` and `screen.pixelDepth` are synonymous. --- # Window | Camoufox # Window ======== #### # Spoof the inner/outer window size, scroll offsets, window position, history length, and more. * * * # Properties ------------ | Property | Type | Description | | --- | --- | --- | | `window.scrollMinX` | int | Minimum horizontal scroll offset | | `window.scrollMinY` | int | Minimum vertical scroll offset | | `window.scrollMaxX` | int | Maximum horizontal scroll offset | | `window.scrollMaxY` | int | Maximum vertical scroll offset | | `window.outerHeight` | uint | Total height of the browser window | | `window.outerWidth` | uint | Total width of the browser window | | `window.innerHeight` | uint | Height of the browser viewport | | `window.innerWidth` | uint | Width of the browser viewport | | `window.screenX` | int | Horizontal distance from the left border | | `window.screenY` | int | Vertical distance from the top border | | `window.history.length` | uint | Number of entries in the session history | | `window.devicePixelRatio` | double | Ratio of physical pixels to CSS pixels | * * * ##### Note Setting the outer window viewport will cause some cosmetic defects to the Camoufox window if the user attempts to manually resize it. Under no circumstances will Camoufox allow the outer window viewport to be resized. --- # Document | Camoufox # Document ========== Spoof the size of the HTML body element. ##### Warning Spoofing document.body has been implemented, but it is more advisable to set `window.innerWidth` and `window.innerHeight` instead. * * * # Properties ------------ | Property | Type | Description | | --- | --- | --- | | `document.body.clientWidth` | uint | Width of the document's body | | `document.body.clientHeight` | uint | Height of the document's body | | `document.body.clientTop` | uint | Width of the top border of the document's body | | `document.body.clientLeft` | uint | Width of the left border of the document's body | --- # Fonts | Camoufox # Fonts ======= Fonts can be passed to be used in Camoufox through the `fonts` config property. | Property | Type | Description | | --- | --- | --- | | `fonts` | array | List of font names to be used | | `fonts:spacing_seed` | uint | Seed to use for font metric spacing randomziation | * * * By default, Camoufox is bundled with the default Windows 11 22H2 fonts, macOS Sonma fonts, and Linux fonts used in the TOR bundle. Camoufox will automatically add the default fonts associated your spoofed User-Agent OS (the value passed in `navigator.userAgent`): Mac OS fonts (from macOS Sonma): [".Al Bayan PUA", ".Al Nile PUA",

This technique is easily detectable by drawing a rectangle and comparing it to an expected result. ### # What Camoufox does Camoufox implements Canvas anti-fingerprinting by using a patched build of [Skia](https://skia.org/) with modified subpixel rendering logic, making it impossible to tell your device apart from a device that renders anti-aliasing in a different way. * * * # Properties ------------ | Property | Type | Description | | --- | --- | --- | | `canvas:aaOffset` | int | Offset each pixel's transparency when drawing anti-aliasing. | | `canvas:aaCapOffset` | bool | By default, the offset will cause the pixel's transparency to wrap around the 0-255 alpha range.
