Can I use Selenium WebDriver with proxy servers?

Yes, you can use Selenium WebDriver with proxy servers. Proxies can be helpful when you need to scrape data anonymously or when you need to access web content that's restricted in your country or testing environment. Configuring Selenium to use a proxy server involves setting up the WebDriver with the desired proxy settings.

Here's how you can configure Selenium WebDriver to use a proxy server in both Python and JavaScript.


In Python, you can use the selenium.webdriver.Proxy class to set up proxy settings, and then you can use these settings when initializing the WebDriver.

from selenium import webdriver
from selenium.webdriver.common.proxy import Proxy, ProxyType

# Configure the proxy settings
proxy_ip_port = 'your_proxy_server:port'
proxy = Proxy({
    'proxyType': ProxyType.MANUAL,
    'httpProxy': proxy_ip_port,
    'ftpProxy': proxy_ip_port,
    'sslProxy': proxy_ip_port,
    'noProxy': ''  # set this value as desired

# Initialize the WebDriver with the proxy settings
options = webdriver.ChromeOptions()
options.Proxy = proxy
options.add_argument("--proxy-server=%s" % proxy_ip_port)

driver = webdriver.Chrome(options=options)

# Now you can use the driver object to make requests through the proxy

JavaScript (Node.js)

In JavaScript, when using the selenium-webdriver package, you can configure the proxy settings directly in the WebDriver options.

const { Builder } = require('selenium-webdriver');
const proxy = require('selenium-webdriver/proxy');

// Configure the proxy settings
const proxyServer = 'http://your_proxy_server:port';

(async function example() {
    let driver = new Builder()
            http: proxyServer,
            https: proxyServer

    try {
        // Now you can use the driver object to make requests through the proxy
        await driver.get('');
    } finally {
        await driver.quit();

Note on Authentication

If your proxy requires authentication (username and password), handling it can be more complex because Selenium does not have built-in support for proxy authentication. A common workaround is to use an intermediate local proxy that adds the necessary authentication headers to the requests. Tools like browsermob-proxy or third-party services can help with this.

Using a WebDriver with Capabilities

You can also set the proxy using capabilities, which can give you more fine-grained control over the Selenium behavior.

from selenium import webdriver

capabilities = webdriver.DesiredCapabilities.CHROME.copy()
capabilities['proxy'] = {
    "httpProxy": proxy_ip_port,
    "ftpProxy": proxy_ip_port,
    "sslProxy": proxy_ip_port,
    "proxyType": "MANUAL",

driver = webdriver.Chrome(desired_capabilities=capabilities)

Remember to replace your_proxy_server:port with the actual host and port of your proxy server. Also, note that the examples above assume you are using Chrome, but similar configurations apply if you are using Firefox (webdriver.Firefox), Edge (webdriver.Edge), or any other browser supported by Selenium.
