Chrome

Headless Browser supports two specialized browser environments, one of which is Chrome. Learn more on how to start using it.

The Headless Browser Chrome environment provides high-performance remote browsers running on dedicated servers and using residential proxies for connection. These browser environments are fast, stable, and highly configurable. They can act as a drop-in replacement for your local browser infrastructure.

Key Features

Fast and stable performance
Any proxy country selection
Compatible with Chrome DevTools Protocol (CDP)

Connection Details

Connect to UBC using the following WebSocket endpoint:

wss://ubc.oxylabs.io

Basic Usage

from playwright.sync_api import sync_playwright

username = "your-username"
password = "your-password"
endpoint = "ubc.oxylabs.io"
browser_url = f"wss://{username}:{password}@{endpoint}"

with sync_playwright() as p:
    browser = p.chromium.connect_over_cdp(browser_url)
    page = browser.new_page()
    page.goto('https://example.com')
    browser.close()

import { chromium } from 'playwright';

(async () => {
    const username = 'your-username';
    const password = 'your-password';
    const endpoint = 'ubc.oxylabs.io';
    const browserUrl = `wss://${username}:${password}@${endpoint}`;

    const browser = await chromium.connectOverCDP(browserUrl);
    const page = await browser.newPage();
    await page.goto('https://example.com');
    await browser.close();
})();

import puppeteer from 'puppeteer';

(async () => {
  const username = 'your-username';
  const password = 'your-password';
  const endpoint = 'ubc.oxylabs.io';
  const browserUrl = `wss://${username}:${password}@${endpoint}`;

  const browser = await puppeteer.connect({
    browserWSEndpoint: browserUrl
  });
  const page = await browser.newPage();
  await page.goto('https://example.com');
  await browser.close();
})();

United States Proxy Infrastructure

Users, who mainly operate in the US, can connect directly to US-based infrastructure via the special entry point. This ensures faster loading time and better browsing efficiency. To establish connection, enter the following:

wss://ubc-us.oxylabs.io

Code examples:

from playwright.sync_api import sync_playwright

username = "your-username"
password = "your-password"
endpoint = "ubc-us.oxylabs.io"
browser_url = f"wss://{username}:{password}@{endpoint}"

with sync_playwright() as p:
    browser = p.chromium.connect_over_cdp(browser_url)
    page = browser.new_page()
    page.goto('https://example.com')
    browser.close()

import { chromium } from 'playwright';

(async () => {
    const username = 'your-username';
    const password = 'your-password';
    const endpoint = 'ubc-us.oxylabs.io';
    const browserUrl = `wss://${username}:${password}@${endpoint}`;

    const browser = await chromium.connectOverCDP(browserUrl);
    const page = await browser.newPage();
    await page.goto('https://example.com');
    await browser.close();
})();

import puppeteer from 'puppeteer';

(async () => {
  const username = 'your-username';
  const password = 'your-password';
  const endpoint = 'ubc-us.oxylabs.io';
  const browserUrl = `wss://${username}:${password}@${endpoint}`;

  const browser = await puppeteer.connect({
    browserWSEndpoint: browserUrl
  });
  const page = await browser.newPage();
  await page.goto('https://example.com');
  await browser.close();
})();

Note: this solution primarily shortens the response time for the US-based users, and should not be confused with proxy geo-location selection. More on that in the following section.

Browser Arguments

Headless Browser Chrome accepts additional browser arguments passed with connection URL in the format of ?bargs=. These GET parameters specify command-line arguments that browsers should be started with.

If the argument should have value, we use bargs=argname:argvalue;
If the argument is just a flag, we use bargs=flagname .

Currently, Oxylabs Headless Browser Chrome supports the following arguments:

Argument

Description

force-color-profile:<profile>

Force all monitors to be treated as though they have the specified color profile.

window-position:X,Y

Specifies the initial window position.

hide-scrollbars

Prevents creating scrollbars for web content – useful for taking consistent screenshots.

enable-features:<feature1>,<feature2>,<feature3>

Comma-separated list of feature names to enable.

disable-notifications

Disables the Web Notification and the Push APIs.

Usage example:

from playwright.sync_api import sync_playwright

username = "your-username"
password = "your-password"
endpoint = "ubc.oxylabs.io"
browser_url = f"wss://{username}:{password}@{endpoint}/?bargs=force-color-profile:srgb&bargs=window-position:100,100"

with sync_playwright() as p:
    browser = p.chromium.connect_over_cdp(browser_url)
    page = browser.new_page()
    page.goto('https://example.com')
    browser.close()
