(see below for more info) - -#### `**kwargs` - -`BrowserSession` can also accept _all_ of the parameters [below](#browserprofile). -(the parameters _above_ this point are specific to `BrowserSession` and cannot be stored in a `BrowserProfile` template) - -Extra `**kwargs` passed to `BrowserSession(...)` act as session-specific overrides to the `BrowserProfile(...)` template. - -```python -base_iphone13 = BrowserProfile( - storage_state='/tmp/auth.json', # share cookies between parallel browsers - **playwright.devices['iPhone 13'], - timezone_id='UTC', -) -usa_phone = BrowserSession( - browser_profile=base_iphone13, - timezone_id='America/New_York', # kwargs override values in base_iphone13 -) -eu_phone = BrowserSession( - browser_profile=base_iphone13, - timezone_id='Europe/Paris', -) - -usa_agent = Agent(task='show me todays schedule...', browser_session=usa_phone) -eu_agent = Agent(task='show me todays schedule...', browser_session=eu_phone) -await asyncio.gather(agent1.run(), agent2.run()) -``` - ---- - -## `BrowserProfile` - -A `BrowserProfile` is a 📋 config template for a 🎭 `BrowserSession(...)`. - -It's basically just a typed + validated version of a `dict` to hold config. - -When you find yourself storing or re-using many browser configs, you can upgrade from: - -```diff -- config = {key: val, key: val, ...} -- BrowserSession(**config) -``` - -To this instead: - -```diff -+ config = BrowserProfile(key=val, key=val, ...) -+ BrowserSession(browser_profile=config) -``` - - -You don't ever *need* to use a `BrowserProfile`, you can always pass config parameters directly to `BrowserSession`: -```python -session = BrowserSession(headless=True, storage_state='auth.json', viewport={...}, ...) -``` - - -`BrowserProfile` is optional, but it provides a number of benefits over a normal `dict` for holding config: - -- has type hints and pydantic field descriptions that show up in your IDE -- validates config at runtime quickly without having to start a browser -- provides helper methods to autodetect screen size, set up local paths, save/load config as json, and more... - - -`BrowserProfiles`s are designed to easily be given 🆔 `uuid`s and put in a database + made editable by users. -`BrowserSession`s get their own 🆔 `uuid`s and be linked by 🖇 foreign key to whatever `BrowserProfiles` they use. - -This cleanly separates the per-connection rows from the bulky re-usable config and avoids wasting space in your db. -This is useful because a user may only have 2 or 3 profiles, but they could have 100k+ sessions within a few months. - - - -`BrowserProfile` and `BrowserSession` can both take any of the: - -- [Playwright parameters](#playwright) -- [Browser-Use parameters](#browser-use-parameters) (extra options we provide on top of `playwright`) - -The only parameters `BrowserProfile` can NOT take are the session-specific connection parameters: -`cdp_url`, `wss_url`, `browser_pid`, etc. - - -Playwright Page/Browser/Context objects are no longer supported as parameters. - - -### Basic Example - -```python -from browser_use.browser import BrowserProfile - -profile = BrowserProfile( - stealth=True, - storage_state='/tmp/google_docs_cookies.json', - allowed_domains=['docs.google.com', 'https://accounts.google.com'], - viewport={'width': 396, 'height': 774}, - # ... playwright args / browser-use config args ... -) - -phone1 = BrowserSession(browser_profile=profile, device_scale_factor=1) -phone2 = BrowserSession(browser_profile=profile, device_scale_factor=2) -phone3 = BrowserSession(browser_profile=profile, device_scale_factor=3) -``` - -### Browser-Use Parameters - -These parameters control Browser Use-specific features, and are outside the standard playwright set. They can be passed to `BrowserSession(...)` and/or stored in a `BrowserProfile` template. - -#### `keep_alive` - -```python -keep_alive: bool | None = None -``` - -If `True` it wont close the browser after the first `agent.run()` ends. Useful for running multiple tasks with the same browser instance. If this is left as `None` and the Agent launched its own browser, the default is to close the browser after the agent completes. If the agent connected to an existing browser then it will leave it open. - -#### `stealth` - -```python -stealth: bool = False -``` - -Set to `True` to use [`patchright`](https://github.com/Kaliiiiiiiiii-Vinyzu/patchright) to avoid bot-blocking. (Might cause issues with some sites, requires manual testing.) - - - -#### `allowed_domains` - -```python -allowed_domains: list[str] | None = None -``` - -List of allowed domains for navigation. If None, all domains are allowed. -Example: `['google.com', '*.wikipedia.org']` - Here the agent will only be able to access `google.com` exactly and `wikipedia.org` + `*.wikipedia.org`. - -Glob patterns are supported: - -- `['example.com']` ✅ will match only `https://example.com/*` exactly, subdomains will not be allowed. - It's always the most secure to list all the domains you want to give the access to explicitly w/ schemes e.g. - `['https://google.com', 'http*://www.google.com', 'https://myaccount.google.com', 'https://mail.google.com', 'https://docs.google.com']` -- `['*.example.com']` ⚠️ **CAUTION** this will match `https://example.com` and _all_ its subdomains. - Make sure _all_ the subdomains are safe for the agent! `abc.example.com`, `def.example.com`, ..., `useruploads.example.com`, `admin.example.com` - -#### `disable_security` - -```python -disable_security: bool = False -``` - - - ⚠️ Setting this to `True` is NOT RECOMMENDED. It completely disables all basic - browser security features. - - -This option is for debugging and interacting across cross-origin iFrames when there are no cookies or sensitive data in use. -It's very INSECURE, under no circumstances should you enable this while using real cookies or sensitive data, visiting a single untrusted URL in this mode can immediately compromise all the profile cookies instantly. Consider a less nuclear option like `bypass_csp=True` instead. - -#### `deterministic_rendering` - -```python -deterministic_rendering: bool = False -``` - - - ⚠️ Setting this to `True` is NOT RECOMMENDED. It can be glitchy & slow, and it - increases chances of getting blocked by anti-bot systems. It's mostly useful - for QA applications. - - -It's a shortcut for adding these launch args: - -- `--deterministic-mode` -- `--js-flags=--random-seed=1157259159` -- `--force-color-profile=srgb` -- `--font-render-hinting=none` -- `--force-device-scale-factor=2` -- `--enable-webgl` - -With these options fonts will look slightly worse than macOS and slightly than Windows, but rendering will be more consistent between OSs and runs. The cost is performance and stability. Software rendering is slower, easier to fingerprint as a bot, and sometimes glitchy. You likely _don't need this option_ unless you're trying to do screenshot diffing. - -#### `highlight_elements` - -```python -highlight_elements: bool = True -``` - -Highlight interactive elements on the screen with colorful bounding boxes. - -#### `viewport_expansion` - -```python -viewport_expansion: int = 500 -``` - -Viewport expansion in pixels. With this you can control how much of the page is included in the context of the LLM: - -- `-1`: All elements from the entire page will be included, regardless of visibility (highest token usage but most complete). -- `0`: Only elements which are currently visible in the viewport will be included. -- `500` (default): Elements in the viewport plus an additional 500 pixels in each direction will be included, providing a balance between context and token usage. - -#### `include_dynamic_attributes` - -```python -include_dynamic_attributes: bool = True -``` - -Include dynamic attributes in selectors for better element targeting. - -#### `minimum_wait_page_load_time` - -```python -minimum_wait_page_load_time: float = 0.25 -``` - -Minimum time to wait before capturing page state for LLM input. - -#### `wait_for_network_idle_page_load_time` - -```python -wait_for_network_idle_page_load_time: float = 0.5 -``` - -Time to wait for network activity to cease. Increase to 3-5s for slower websites. This tracks essential content loading, not dynamic elements like videos. - -#### `maximum_wait_page_load_time` - -```python -maximum_wait_page_load_time: float = 5.0 -``` - -Maximum time to wait for page load before proceeding. - -#### `wait_between_actions` - -```python -wait_between_actions: float = 0.5 -``` - -Time to wait between agent actions. - -#### `cookies_file` - -```python -cookies_file: str | None = None -``` - -JSON file path to save cookies to. - - -This option is DEPRECATED. Use [`storage_state`](#storage-state) instead, it's the standard playwright format and also supports `localStorage` and `indexedDB`! - -The library will automatically save a new `storage_state.json` next to any `cookies_file` path you provide, just use `storage_state='path/to/storage_state.json' to switch to the new format: - -`cookies_file.json`: `[{cookie}, {cookie}, {cookie}]` -⬇️ -`storage_state.json`: `{"cookies": [{cookie}, {cookie}, {cookie}], "origins": {... optional localstorage state ...}}` - -Or run `playwright open https://example.com/ --save-storage=storage_state.json` and log into any sites you need to generate a fresh storage state file. - - - -#### `profile_directory` - -```python -profile_directory: str = 'Default' -``` - -Chrome profile subdirectory name inside of your `user_data_dir` (e.g. `Default`, `Profile 1`, `Work`, etc.). -No need to set this unless you have multiple profiles set up in a single `user_data_dir` and need to use a specific one. - -#### `window_position` - -```python -window_position: dict | None = {"width": 0, "height": 0} -``` - -Window position from top-left corner. - -#### `save_recording_path` - -```python -save_recording_path: str | None = None -``` - -Directory path for saving video recordings. - -#### `trace_path` - -```python -trace_path: str | None = None -``` - -Directory path for saving Agent trace files. Files are automatically named as `{trace_path}/{context_id}.zip`. - ---- - - - - -### Playwright Launch Options - -All the parameters below are standard playwright parameters and can be passed to both `BrowserSession` and `BrowserProfile`. -They are defined in `browser_use/browser/profile.py`. See here for the [official Playwright documentation](https://playwright.dev/python/docs/api/class-browsertype#browser-type-launch-persistent-context) for all of these options. - -#### `headless` - -```python -headless: bool | None = None -``` - -Runs the browser without a visible UI. If None, auto-detects based on display availability. If you set `headless=False` on a server with no monitor attached, the browser will fail to launch (use `xvfb` + vnc to give a headless server a virtual display you can remote control). - -`headless=False` is recommended for maximum stealth and is required for human-in-the-loop workflows. - -#### `channel` - -```python -channel: BrowserChannel = 'chromium' -``` - -Browser channel: `['chromium']` (default when `stealth=False`), `'chrome'` (default when `stealth=True`), `'chrome-beta'`, `'chrome-dev'`, `'chrome-canary'`, `'msedge'`, `'msedge-beta'`, `'msedge-dev'`, `'msedge-canary'` - -Don't worry, other chromium-based browsers not in this list (e.g. `brave`) are still supported if you provide your own [`executable_path`](#executable_path), just set it to `chromium` for those. - -#### `executable_path` - -```python -executable_path: str | Path | None = None -``` - -Path to browser executable for custom installations. - -#### `user_data_dir` - -```python -user_data_dir: str | Path | None = '~/.config/browseruse/profiles/default' -``` - -Directory for browser profile data. Set to `None` to use an ephemeral temporary profile (aka incognito mode). - -Multiple running browsers **cannot share a single `user_data_dir` at the same time**. You must set it to `None` or -provide a unique `user_data_dir` per-session if you plan to run multiple browsers. - -The browser version run must always be equal to or greater than the version used to create the `user_data_dir`. -If you see errors like `Failed to parse Extensions` or similar and failures when launching, you're attempting to run an older browser with an incompatible `user_data_dir` that's already been migrated to a newer schema version. - -#### `args` - -```python -args: list[str] = [] -``` - -Additional command-line arguments to pass to the browser. See here for the [full list of available chrome launch options](https://peter.sh/experiments/chromium-command-line-switches/). - -#### `ignore_default_args` - -```python -ignore_default_args: list[str] | bool = ['--enable-automation', '--disable-extensions'] -``` - -List of default CLI args to stop playwright from including when launching chrome. Set it to `True` to disable _all_ default options (not recommended). - -#### `env` - -```python -env: dict[str, str] = {} -``` - -Extra environment variables to set when launching browser. e.g. `{'DISPLAY': '1'}` to use a specific X11 display. - -#### `chromium_sandbox` - -```python -chromium_sandbox: bool = not IN_DOCKER -``` - -Whether to enable Chromium sandboxing (recommended for security). Should always be `False` when running inside Docker -because Docker provides its own sandboxing can conflict with Chrome's. - -#### `devtools` - -```python -devtools: bool = False -``` - -Whether to open DevTools panel automatically (only works when `headless=False`). - -#### `slow_mo` - -```python -slow_mo: float = 0 -``` - -Slow down actions by this many milliseconds. - -#### `timeout` - -```python -timeout: float = 30000 -``` - -Default timeout in milliseconds for connecting to a remote browser. - -#### `accept_downloads` - -```python -accept_downloads: bool = True -``` - -Whether to automatically accept all downloads. - -#### `proxy` - -```python -proxy: ProxySettings | None = None -``` - -Proxy settings (typed). Example: - -```python -proxy=ProxySettings(server="http://proxy.com:8080", username="user", password="pass") -``` - -#### `permissions` - -```python -permissions: list[str] = ['clipboard-read', 'clipboard-write', 'notifications'] -``` - -Browser permissions to grant.

The LLM only ever sees the `x_member_number` and `x_passphrase` placeholders in prompts -2. When the model wants to use your password it outputs x_passphrase - and we replace it with the actual value in the DOM -3. When sensitive data appear in the content of the current page, we replace it in the page summary fed to the LLM - so that the model never has it in its state. -4. The browser will be entirely prevented from going to any site not under `https://*.example.com` - -This approach ensures that sensitive information remains secure while still allowing the agent to perform tasks that require authentication. - ---- - -### Best Practices - -- Always restrict your sensitive data to only the exact domains that need it, `https://travel.example.com` is better than `*.example.com` -- Always restrict [`Browser(allowed_domains=[...])`](https://docs.browser-use.com/customize/browser-settings#allowed-domains) to only the domains the agent needs to visit to accomplish its task. This helps guard against prompt injection attacks, jailbreaks, and LLM mistakes. -- Only use `sensitive_data` for strings that can be inputted verbatim as text. The LLM never sees the actual values, so it can't "understand" them, adapt them, or split them up for multiple input fields. For example, you can't ask the Agent to click through a datepicker UI to input the sensitive value `1990-12-31`. For these situations you can implement a [custom function](/customize/custom-functions) the LLM can call that updates the DOM using Python / JS. -- Don't use `sensitive_data` for login credentials, it's better to use [`storage_state`](docs.browser-use.com/customize/browser-settings#storage-state) or a [`user_data_dir`](/customize/browser-settings#user-data-dir) to log into the sites the agent needs in advance & reuse the cookies: - -```bash -# open a browser to log into the sites you need & save the cookies -$ playwright open https://accounts.google.com --save-storage auth.json -``` - -Then use those cookies when the agent runs: - -```python -agent = Agent(..., browser=Browser(storage_state='./auth.json')) -``` - - - -Warning: Vision models still see the screenshot of the page by default - where the sensitive data might be visible. - -It's recommended to set `Agent(use_vision=False)` when working with `sensitive_data`. - - - - - - -### Allowed Domains - -Domain patterns in `sensitive_data` follow the same format as [`allowed_domains`](https://docs.browser-use.com/customize/browser-settings#allowed-domains): - -- `example.com` - Matches only `https://example.com/*` -- `*.example.com` - Matches `https://example.com/*` and any subdomain `https://*.example.com/*` -- `http*://example.com` - Matches both `http://` and `https://` protocols for `example.com/*` -- `chrome-extension://*` - Matches any Chrome extension URL e.g. `chrome-extension://anyextensionid/options.html` - -> **Security Warning**: For security reasons, certain patterns are explicitly rejected: -> -> - Wildcards in TLD part (e.g., `example.*`) are **not allowed** (`google.*` would match `google.ninja`, `google.pizza`, etc. which is a bad idea) -> - Embedded wildcards (e.g., `g*e.com`) are rejected to prevent overly broad matches -> - Multiple wildcards like `*.*.domain` are not supported currently, open an issue if you need this feature - -The default protocol when no scheme is specified is now `https://` for enhanced security. - -For convenience the system will validate that all domain patterns used in `Agent(sensitive_data)` are also included in `Browser(allowed_domains)`. - -### Missing or Empty Values - -When working with sensitive data, keep these details in mind: - -- If a key referenced by the model (`key_name`) is missing from your `sensitive_data` dictionary, a warning will be logged but the substitution tag will be preserved. -- If you provide an empty value for a key in the `sensitive_data` dictionary, it will be treated the same as a missing key. -- The system will always attempt to process all valid substitutions, even if some keys are missing or empty. - ---- - -### Full Example - -Here's a more complex example demonstrating multiple domains and sensitive data values. - -```python -from dotenv import load_dotenv -load_dotenv() - -from browser_use.llm import ChatOpenAI -from browser_use import Agent, Browser - - -llm = ChatOpenAI(model='gpt-4.1') - -# Domain-specific sensitive data -sensitive_data = { - 'https://*.google.com': {'x_email': '...', 'x_pass': '...'}, - 'chrome-extension://abcd1243': {'x_api_key': '...'}, - 'http*://example.com': {'x_authcode': '123123'} -} - -# Set browser session with allowed domains that match all domain patterns in sensitive_data -browser = Browser( - allowed_domains=[ - 'https://*.google.com', - 'chrome-extension://abcd', - 'http://example.com', # Explicitly include http:// if needed - 'https://example.com' # By default, only https:// is matched - ] -) - -# Pass the sensitive data to the agent -agent = Agent( - task="Log into Google, then check my account information", - llm=llm, - sensitive_data=sensitive_data, - browser=browser, - use_vision=False, -) - -async def main(): - await agent.run() - -if __name__ == '__main__': - asyncio.run(main()) -``` - -With this approach: - -1.
