It's needed primarily for the implementation of other plugins for various frameworks.\n\n**Warning:** plugin is still in beta stage, it means that bugs may happen, including critical.\n\nCurrent supported engine version - **135.0.7049.42**.\n\n**IMPORTANT NOTE:** plugin only work on **Windows** operating system, it cannot be installed and used on **Linux**, **macOS** and other systems!\n\n## About\n\nThis library allows you to change browser fingerprint and use any automation framework with enhanced anonymity.\nIn order to migrate and use it, a minimum of modifications and code changes is required.\n\n**Browser fingerprinting** - is a technique that allows to identify the user by a combination of browser properties, such as - fonts, resolution, list of plugins, navigator properties, etc.\nBy adding new factors and using browser **API** in a special way, a site can determine exactly which user is visiting it, even if the user is using a proxy.\nWhen using this package and replacing fingerprints, websites will not be able to identify you from other users, as all these properties and results of **API** calls will be replaced with values from real devices.\n\nLet's look at a small example of **WebGL** property substitution.\nIn the screenshot below, the left column shows the values from the regular browser, and the right column shows the values substituted using ready-made fingerprints.\nThis result cannot be achieved using only the replacement of various browser properties via **JavaScript**, that's what this plugin and service is for:\n\n![WebGL](https://github.com/CheshireCaat/browser-with-fingerprints/raw/master/assets/webgl.jpg)\n\nYou can learn more by following [this](https://fp.bablosoft.com/#capabilities) link.\n\n## Installation\n\nTo use this plugin in your project, install it with your favorite package manager:\n\n```bash\nnpm i browser-with-fingerprints\n# or\npnpm i browser-with-fingerprints\n# or\nyarn add browser-with-fingerprints\n```\n\nPlease note that according to the [architecture](#architecture) section, this plugin can only be installed and used on **Windows** operating system.\n\n## Other plugins\n\nYou can use this package directly to launch browsers and write your own plugins. But it's much better to use ready-made plugins for popular automation frameworks:\n\n- Plugin for **selenium** - [selenium-with-fingerprints](https://github.com/CheshireCaat/selenium-with-fingerprints)\n- Plugin for **puppeteer** - [puppeteer-with-fingerprints](https://github.com/CheshireCaat/puppeteer-with-fingerprints)\n- Plugin for **playwright** - [playwright-with-fingerprints](https://github.com/CheshireCaat/playwright-with-fingerprints)\n\nThese plugins are already configured to integrate with each specific library, and have a convenient **API** to work with. They aren't a complete replacement for automation frameworks, but only extend their functionality.\n\nTo launch the browser, the most compatible **API** is used, copying the options of the original libraries so that it's easy to add new code to your project. You can find detailed information in the corresponding repositories.\n\nWhen using plugins, don't forget about dependencies. Libraries do not install dependencies directly, they are listed as optional to make things easier for you.\nAlso, keep in mind the potential need for additional packages or programs - for example, the **chromedriver** executable for the **selenium-webdriver** package, and so on.\n\n## Common problems\n\nYou can find information about known issues related to updates, as well as ways to solve them in [this](./MIGRATION.md) guide.\n\n### Engine errors\n\nIf you encounter errors while installing or downloading the engine, use the following recommendations:\n\n1. Do not install the engine folder into the profile folder, otherwise the entire procedure will be performed every time you launch.\n2. Increase the timeout using the **setEngineTimeout** method, or at least disable it by passing `0` as a parameter.\n3. Some ISPs may block domains for engine downloading, check this option as well.\n4. You can try to download and move the engine to the desired folder manually.\n\n### Request errors\n\nIf you encounter errors while executing plugin methods, use the following recommendations:\n\n1. Check that your antivirus or built-in defender does not block or delete engine files.\n2. Some ISPs may block domains for fingerprinting and IP address detection, check this option as well.\n3. Increase the timeout using the **setRequestTimeout** method, or at least disable it by passing `0` as a parameter.\n\nIf the recommendations do not help or the problem is not described in this section, open a new issue, having first checked (including in other repositories) for the presence of similar tickets.\n\n## Launching the browser\n\nYou can launch the browser in two different ways. There are two methods for this - **launch** and **spawn**.\n\nThe first one uses the native launcher of the library, the integration with which is implemented in a specific plugin.\nThis does not apply to the base library and this method cannot be used with it.\n\nThe **launch** method uses the framework's built-in methods to launch the browser under the hood and, accordingly, accepts the same options.\nThe only difference is the presence of additional code inside the plugin that applies the fingerprint and proxy. The sample code may look something like this:\n\n```js\nconst browser = await plugin.launch({\n  args: ['--mute-audio'],\n  headless: true,\n});\n```\n\nThe **spawn** method works in a similar way, but uses a separate mechanism to launch the browser.\nThe main difference is that this method just starts the process, but doesn't connect to it for automation - you can do it yourself later.\n\nThis method returns a running browser instance that can be used to connect via **CDP** or via the desired automation framework:\n\n```js\nconst { plugin } = require('browser-with-fingerprints');\n\nconst chrome = await plugin.spawn({ headless: true });\n\n// Pseudocode for setting up a\n// connection using the debugging port.\nawait framework.connect({ debuggingPort: chrome.port });\n\n// Pseudocode for setting up a\n// connection using the websocket url.\nawait framework.connect({ websocketUrl: chrome.url });\n\n// The best way to close the browser\n// is to use the framework methods.\nawait chrome.close();\n```\n\nAt [this](src/plugin/launcher/index.d.ts#L54) link you can find a detailed description of all the options allowed for **spawn** method.\nThe same goes for the return type declaration, details of which can be found [here](src/plugin/launcher/index.d.ts#L6).\n\nIf possible, use it only in extreme cases. It is much more convenient to use the **launch** method to launch the browser, which minimizes the number of steps for proper initialization and configuration.\n\nAnnotations are described for all plugins methods directly in the library code via the **TypeScript** declarations, so when using it you will be able to see hints for all options and types.\nYou can also find out about it directly [here](src/index.d.ts).\n\n## Configuring plugin\n\nAt the moment, it is possible to change the service key, working folder and timeout for requests to the engine, which is used when fetching, applying fingerprints, and so on:\n\n```js\n// Set the fingerprint service key for all plugin methods that require it.\nplugin.setServiceKey('SERVICE_KEY');\n\n// Set the folder where the plugin engine will be installed:\nplugin.setWorkingFolder('./engine');\n\n// Set the timeout used when fetching fingerprints and so on:\nplugin.setRequestTimeout(5 * 60000);\n\n// Set the timeout used when installing/downloading engine:\nplugin.setEngineTimeout(10 * 60000);\n```\n\nThe methods from the example above change the settings globally, that is, for all instances of the plugin.\n\nThe default values are the `./data` directory for the working folder and `300000` milliseconds for the request timeout.\n\nAn empty string is used for the fingerprint service key by default, which means that the free version of the service will be used.\n\n## Configuring browser\n\nIn order to change the fingerprint and proxy for your browser, you should use special separate methods:\n\n- **useProxy** - to change the proxy configuration.\n- **useProfile** - to change the profile configuration.\n- **useFingerprint** - to change the fingerprint configuration.\n\nThese methods directly affect only the next launch of the browser. So you should always use them before using the `spawn` plugin method.\n\nYou cannot change the settings once the browser is launched - more specifically, an already launched instance will not be affected by the new configuration.\nBut you can safely change the options for the next run, or for a separate browser instance with a different unique configuration.\n\nYou can also **chain** calls, since all these methods return the current plugin instance. It does not matter in which order the settings will be applied. It might look like this:\n\n```js\nconst { plugin } = require('browser-with-fingerprints');\n\n// Set the service key for the plugin (you can buy it here https://bablosoft.com/directbuy/FingerprintSwitcher/2).\n// Leave an empty string to use the free version.\nplugin.setServiceKey('');\n\nconst fingerprint = await plugin.fetch({\n  tags: ['Microsoft Windows', 'Chrome'],\n});\n\nplugin.useProxy('127.0.0.1:8080').useFingerprint(fingerprint);\n```\n\nUse these links to see a detailed description of the methods:\n\n- [This](src/index.d.ts#L94) one for the **useFingerprint** method (also see additional options [here](src/types/fingerprint.d.ts#L4)).\n- [This](src/index.d.ts#L124) one for the **useProfile** method (also see additional options [here](src/types/profile.d.ts#L4)).\n- [This](src/index.d.ts#L152) one for the **useProxy** method (also see additional options [here](src/types/proxy.d.ts#L24)).\n\nThe usage of these methods is very similar - each takes two parameters, the first of which is the configuration data itself, and the second is additional options.\nThe fingerprint and proxy will not be changed unless the appropriate method is used. In this case, all settings related to browser fingerprinting will remain at their original values.\n\nFingerprint and proxy aren't applied instantly when calling methods. Instead, the configuration is saved and used directly when the browser is launched using the **launch** or **spawn** methods.\nThus, you can pre-configure the plugin in a certain way, or change something immediately before launching the browser.\n\n### Configuring browser version\n\nYou can change the browser version right while using the plugin - the engine may come with several different builds of the browser.\n\nIn order to do this, use the **useBrowserVersion** method or the **version** property (deprecated).\nThe last one defaults to `default`, which means that the latest available version will be used:\n\n```js\nconst { plugin } = require('browser-with-fingerprints');\n\n// Use a specific version:\nplugin.useBrowserVersion('115.0.5790.99');\n\n// Use the latest available version:\nplugin.useBrowserVersion('default');\n```\n\nIf you specify an unavailable or invalid version, an appropriate error will be thrown when the browser starts.\nAlso keep in mind that this property only affects a specific instance of the plugin, not the entire library.\n\nIn order to get a list of available versions shipped with the engine, use the **versions** method.\nIt returns a list of browser versions as strings or objects with additional information, depending on the format passed:\n\n```js\nconst { plugin } = require('browser-with-fingerprints');\n\n// The list of versions is always sorted in descending order:\nawait plugin.versions('extended').then((versions) =\u003e {\n  // The latest available browser version will be used:\n  plugin.useBrowserVersion(versions[0]['browser_version']);\n});\n```\n\nThanks to this, you can, for example, use the version that corresponds to a certain fingerprint, and vice versa.\n\n### Fingerprint usage\n\nIn order to change the fingerprint, you need to run the `useFingerprint` method before starting the browser, i.e. before using the plugin's `launch` method.\n\nThe `useFingerprint` method takes two parameters.\nThe first is a string with fingerprint data that you can request from the service.\nThe second is additional options for applying a fingerprint, most of which are applied automatically - for example, the safe replacement of the **BatteryAPI** and **AudioAPI** properties:\n\n```js\nconst { plugin } = require('browser-with-fingerprints');\n\n// Set the service key for the plugin (you can buy it here https://bablosoft.com/directbuy/FingerprintSwitcher/2).\n// Leave an empty string to use the free version.\nplugin.setServiceKey('');\n\nconst fingerprint = await plugin.fetch({\n  tags: ['Microsoft Windows', 'Chrome'],\n});\n\nplugin.useFingerprint(fingerprint, {\n  // It's disabled by default.\n  safeElementSize: true,\n  // It's enabled by default.\n  safeBattery: false,\n});\n```\n\nIn order to obtain fingerprints you should use the **fetch** plugin method.\nPass the service key as the first argument for the **serviceKey** and additional parameters for the **fetch**, if necessary:\n\n```js\nconst { plugin } = require('browser-with-fingerprints');\n\n// Set the service key for the plugin (you can buy it here https://bablosoft.com/directbuy/FingerprintSwitcher/2).\n// Leave an empty string to use the free version.\nplugin.setServiceKey('');\n\nconst fingerprint = await plugin.fetch({\n  tags: ['Microsoft Windows', 'Chrome'],\n  // Fetch fingerprints only with a browser version higher than 115:\n  minBrowserVersion: 115,\n  // Fetch fingerprints only with a browser version lower than 119:\n  maxBrowserVersion: 119,\n  // Fetch fingerprints only collected in the last 15 days:\n  timeLimit: '15 days',\n});\n```\n\nIn order to use filters and many other settings from the example above, you will need a premium key, the same applies to tags that differ from the default ones:\n\n```js\nconst { plugin } = require('browser-with-fingerprints');\n\n// Set the service key for the plugin (you can buy it here https://bablosoft.com/directbuy/FingerprintSwitcher/2).\nplugin.setServiceKey('SERVICE_KEY');\n\n// In order to use custom tags you need the premium key:\nconst fingerprint = await plugin.fetch({\n  tags: ['Android', 'Chrome'],\n});\nplugin.useFingerprint(fingerprint);\n\nawait plugin.spawn();\n```\n\nAll possible settings for **fetch** method, as well as their descriptions, you can find [here](src/types/fetch.d.ts#L35).\n\nThe special `current` value can be used to filter fingerprints by browser version - in this case, the version installed for the plugin will be used.\nIt can be very convenient as the browser and fingerprint versions will be exactly the same and you don't have to enter the exact values in multiple places.\n\nYou can **reuse** fingerprints instead of requesting new ones each time.\nTo do this, you can save them to a file or to a database - use any option convenient for you.\nIn this way, you can speed up the process of launching the browser with the parameters you need, organize your storage, filter and sort fingerprints locally, and much more:\n\n```js\nconst { readFile, writeFile } = require('fs/promises');\nconst { plugin } = require('browser-with-fingerprints');\n\n// Set the service key for the plugin (you can buy it here https://bablosoft.com/directbuy/FingerprintSwitcher/2).\n// Leave an empty string to use the free version.\nplugin.setServiceKey('');\n\n// Save the fingerprint to a file:\nconst fingerprint = await plugin.fetch({\n  tags: ['Microsoft Windows', 'Chrome'],\n});\nawait writeFile('fingerprint.json', fingerprint);\n\n// Load fingerprint from file at next run:\nplugin.useFingerprint(await readFile('fingerprint.json', 'utf8'));\n```\n\nYou can learn more about the options directly when adding these methods - just use the built-in [annotations](src/index.d.ts#L214).\n\nYou can use any [tags](src/types/fetch.d.ts#L13), filters (e.g. [time](src/types/fetch.d.ts#L6) limit) and settings if you have a service key.\n\nIf you specify an empty string as the first argument for the `fetch` or the `setServiceKey` method, the free version will be used.\nFor a free version you won't be able to use other tags than the default ones, as well as some other filters:\n\n```js\n// Set the service key for the plugin (you can buy it here https://bablosoft.com/directbuy/FingerprintSwitcher/2).\n// Leave an empty string to use the free version.\nplugin.setServiceKey('');\n\nconst fingerprint = await plugin.fetch({\n  // You can only use these tags with the free version:\n  tags: ['Microsoft Windows', 'Chrome'],\n  // You also cannot use such filters in the free version:\n  // minBrowserVersion: 115,\n});\n```\n\nIn the free version, the [PerfectCanvas](https://wiki.bablosoft.com/doku.php?id=perfectcanvas) technology is also not available.\nThere are other limitations when using the free version - for example, limiting the number of requests in a certain period of time.\nTo see the differences and limits of different versions, visit [this](https://fp.bablosoft.com/#pricing) website.\n\nYou can buy a key [here](https://bablosoft.com/directbuy/FingerprintSwitcher/2) to avoid limitations.\n\n### Profile usage\n\nIn order to use a specific browser profile, you can, among other options, use the `useProfile` method.\nAs the first parameter, it takes the path to the profile folder - the same value that you specify, for example, for the `user-data-dir` argument.\nThe second parameter is additional options that are primarily responsible for loading fingerprint and proxy data from the profile folder:\n\n```js\nconst path = require('path');\nconst { plugin } = require('browser-with-fingerprints');\n\n// Set the service key for the plugin (you can buy it here https://bablosoft.com/directbuy/FingerprintSwitcher/2).\n// Leave an empty string to use the free version.\nplugin.setServiceKey('');\n\n// The key may be required if the fingerprint will be used from the profile.\nplugin.useProfile(path.resolve('./profile'), {\n  // Don't load fingerprint from profile folder:\n  loadFingerprint: false,\n  // Don't load proxy from profile folder:\n  loadProxy: false,\n});\n```\n\nBy default, the plugin will load proxy and fingerprint data from the profile folder, if they are written there.\nYou can change this behavior by setting the options to `false` - for example, if you are not sure that the stored proxy is working.\nPlease note that if you add your fingerprint or proxy through the appropriate methods, then the data you specified will be used regardless of the options.\n\nYou can also use other options to set the path to the profile folder, such as the `userDataDir` option, if you don't need additional settings:\n\n```js\nconst path = require('path');\nconst { plugin } = require('browser-with-fingerprints');\n\nconst browser = await plugin.spawn({\n  userDataDir: './profile',\n  // Browser arguments can be used as well:\n  args: [`--user-data-dir=${path.resolve('./profile')}`],\n});\n```\n\nAfter launching a browser with your profile, the fingerprint and proxy data you specified will always be stored in the profile folder.\nThis setting itself is saved between browser launches, that is, it behaves in the same way as other similar methods.\nTo run different profiles, you need to call this method again with different values for the profile directory.\n\nYou can learn more about the parameters and additional options for this method [here](src/index.d.ts#L124) and [here](src/types/profile.d.ts#L4).\n\n### Proxy usage\n\nIn order to set up a proxy, you should use the `useProxy` method.\nThe first parameter of this method is a string with information about the proxy.\nThe second parameter is additional options that will be applied to the browser, for example, automatic change of language and time zone:\n\n```js\nconst { plugin } = require('browser-with-fingerprints');\n\nplugin.useProxy('127.0.0.1:8080', {\n  // Change browser timezone according to proxy:\n  changeTimezone: true,\n  // Replace browser geolocation according to proxy:\n  changeGeolocation: true,\n});\n```\n\nYou can learn more about the parameters and additional options for this method [here](src/index.d.ts#L152) and [here](src/types/proxy.d.ts#L24).\n\nThe browser supports two types of proxies - **https** and **socks5**.\nIt is better to always specify the proxy type in the address line - otherwise, **https** will be used by default.\n\nYou can use aliases - **http** instead of **https** and **socks** instead of **socks5**.\nProxies with authorization (with login and password) are also supported.\n\nIn general, when specifying addresses, you can use many different formats, for example:\n\n- `127.0.0.1:8080`\n- `https://127.0.0.1:8080`\n- `socks5://127.0.0.1:8181`\n- `username:password@127.0.0.1:8080`\n- `socks:127.0.0.1:8080:username:password`\n- `https://username:password:127.0.0.1:8080`\n\nIn order to preserve compatibility with the original library syntax, the proxy can be obtained from the arguments you specified.\nThe `proxy-server` option will be used as the value, and all other options will be set to their default values.\nBut this will be done only if you didn't call the appropriate method for the proxy configuration:\n\n```js\nconst { plugin } = require('browser-with-fingerprints');\n\nconst browser = await plugin.spawn({\n  // The syntax for specifying an argument value\n  // is exactly the same as for using a separate method.\n  args: ['--proxy-server=https://127.0.0.1:8080'],\n});\n```\n\nIt's better to replace such code with the `useProxy` method. This is much more convenient because you can immediately set the additional options you need.\n\n### More info\n\nIf you want to learn more about fingerprint substitution technology, explore the list of replaceable properties and various options, such as tags, get or configure your service key, use [this](https://fp.bablosoft.com) link.\nThere you can also get a test fingerprint and see ready-made values that can be applied to your browser.\n\n## Architecture\n\nThis plugin uses the [FingerprintSwitcher](https://fp.bablosoft.com) service to get fingerprints.\nThe resulting fingerprints are used later directly when working with the browser and are applied in a special way using a custom configuration files.\n\nAlso keep in mind that this package only work on the **Windows** operating system.\nThis is a forced measure due to the presence of some critical **Windows-only** dependencies without which this implementation will not work.\nIf you install or run it on other platforms, you will get the corresponding errors.\n\nThere are some **limitations** in using the package, which may be critical or non-critical depending on your task.\nFor example, for the correct operation of the fingerprint substitution technology, a custom browser with various patches is required.\nIt will be used automatically when working with this package.\n\nThe plugin architecture can be summarized as the following diagram:\n\n![Architecture](https://github.com/CheshireCaat/browser-with-fingerprints/raw/master/assets/plugin.jpg)\n\nAll packages can only work with the **Chrome** browser, which comes bundled with the libraries and loads automatically.\nThe path to the executable file is defined on the plugin side and cannot be changed.\nIt means that you will not be able to use not only other versions of **Chrome** or **Chromium**, but also other browser engines.\nThe same goes for some framework-specific launch options.\n\n### Limitations\n\nPlease **note** that there are some restrictions at the moment:\n\n- Only **Windows** operating system is supported.\n- Parallel launch of browsers is synchronized between calls.\n- Working with **workers** is possible only when specifying a separate working folder for each of them.\n\nAlso, there is no guarantee that each of these items will be changed in the future.\n\n## Alternatives\n\nAlso check out [BAS](https://bablosoft.com/shop/BrowserAutomationStudio) - a great alternative to automate the **Chrome** browser without programming skills.\nIt also supports fingerprint substitution, has simple and powerful multithreading and other advantages.\n\n## Troubleshooting\n\nIf you encounter any issue or bug, please use the [issues](https://github.com/CheshireCaat/browser-with-fingerprints/issues) section of the repository.\n\nPlease describe the problem in as much detail as possible when creating tickets - indicate the sequence of actions (steps) to repeat the problem, error output, and so on.\n\nIf the code is large, attach it as files or use sandboxes. At the same time, it's better to remove from it areas that do not relate to the problem - it will be much easier to figure it out.\nFormat your code and wrap it in special **markdown** tags if you're adding it to an issue report, for example:\n\n```js\n// your code\n```\n\nPlease be careful not to attach various **secrets** in your code or screenshots - for example, fingerprint service keys, account passwords, and so on.\nIn the case of service keys, this can lead to their blocking without a refund.\n\nIf the recommendations are not followed, your ticket may be ignored.\n\n## Testing\n\nThe excellent [mocha](https://github.com/mochajs/mocha) framework is used for tests in this library.\nUse the command line or ready-made scripts if you want to run them yourself.\n\nIn order to test getting fingerprints from the service (as well as premium functionality), set the **FINGERPRINT_KEY** environment variable:\n\n```properties\nFINGERPRINT_KEY=\"VALUE\"\n```\n\nThis variable will be used when calling the **fetch** method.\nYou can also use the **FINGERPRINT_CWD** environment variable to specify the directory where the engine will be stored, for example:\n\n```properties\nFINGERPRINT_CWD=\"../plugin-engine\"\n```\n\nThe **FINGERPRINT_TIMEOUT** variable can be set if it's necessary to change the default timeout for executing engine methods, such as applying or fetching a fingerprint:\n\n```properties\nFINGERPRINT_TIMEOUT=300000\n```\n\nYou can define it in any way convenient for you, but by default variables are read from the **env** files using the [dotenv](https://github.com/motdotla/dotenv) library.\n\n## License\n\nCopyright © 2025, [CheshireCaat](https://github.com/CheshireCaat).
