Apify extends the launch options of Puppeteer. You can use any of the Puppeteer compatible LaunchOptions options by providing the launchOptions property.


// launch a headless Chrome (not Chromium)
const launchContext = {
// Apify helpers
useChrome: true,
proxyUrl: ''
// Native Puppeteer options
launchOptions: {
headless: true,
args: ['--some-flag'],





experimentalContainers?: boolean

Like useIncognitoPages, but for persistent contexts, so cache is used for faster loading. Works best with Firefox. Unstable on Chromium.


launchOptions?: PuppeteerLaunchOptions

puppeteer.launch options


launcher?: unknown

Already required module (Object). This enables usage of various Puppeteer wrappers such as puppeteer-extra.

Take caution, because it can cause all kinds of unexpected errors and weird behavior. Crawlee is not tested with any other library besides puppeteer itself.


proxyUrl?: string

URL to a HTTP proxy server. It must define the port number, and it may also contain proxy username and password.



useChrome?: boolean = ```ts false ```

If true and executablePath is not set, Puppeteer will launch full Google Chrome browser available on the machine rather than the bundled Chromium. The path to Chrome executable is taken from the CRAWLEE_CHROME_EXECUTABLE_PATH environment variable if provided, or defaults to the typical Google Chrome executable location specific for the operating system. By default, this option is false.


useIncognitoPages?: boolean = ```ts false ```

With this option selected, all pages will be opened in a new incognito browser context. This means they will not share cookies nor cache and their resources will not be throttled by one another.


userAgent?: string

The User-Agent HTTP header used by the browser. If not provided, the function sets User-Agent to a reasonable default to reduce the chance of detection of the crawler.


userDataDir?: string

Sets the User Data Directory path. The user data directory contains profile data such as history, bookmarks, and cookies, as well as other per-installation local state. If not specified, a temporary directory is used instead.
