Selenium

We're happy to support the web-driver protocol, largely used by Selenium. You'll likely need to consult your libraries documentation since there's many options and alternatives for remote connections. Below is a small example of using the chrome-webdriver library and how to use browserless with it.

Before

const webdriver = require('selenium-webdriver');
const fs = require('fs');

const chromeCapabilities = webdriver.Capabilities.chrome();
chromeCapabilities.set('goog:chromeOptions', {
  // Set args similar to puppeteer's for best performance
  args: [
    '--disable-background-timer-throttling',
    '--disable-backgrounding-occluded-windows',
    '--disable-breakpad',
    '--disable-component-extensions-with-background-pages',
    '--disable-dev-shm-usage',
    '--disable-extensions',
    '--disable-features=TranslateUI,BlinkGenPropertyTrees',
    '--disable-ipc-flooding-protection',
    '--disable-renderer-backgrounding',
    '--enable-features=NetworkService,NetworkServiceInProcess',
    '--force-color-profile=srgb',
    '--hide-scrollbars',
    '--metrics-recording-only',
    '--mute-audio',
    '--headless',
    '--no-sandbox',
  ],
});

const driver = new webdriver.Builder()
  .forBrowser('chrome')
  .withCapabilities(chromeCapabilities)
  .build();

(async () => {
  try {
    await driver.get('https://www.example.com/');

    // Take screenshot of results page. Save to disk.
    const base64png = await driver.takeScreenshot();
    fs.writeFileSync('.no-git/screenshot.png', new Buffer(base64png, 'base64'));
  } finally {
    driver.quit();
  }
})();

After

const webdriver = require('selenium-webdriver');
const fs = require('fs');

const chromeCapabilities = webdriver.Capabilities.chrome();
chromeCapabilities.set('browserless:token', 'YOUR-API-TOKEN');
chromeCapabilities.set('goog:chromeOptions', {
  args: [
    '--disable-background-timer-throttling',
    '--disable-backgrounding-occluded-windows',
    '--disable-breakpad',
    '--disable-component-extensions-with-background-pages',
    '--disable-dev-shm-usage',
    '--disable-extensions',
    '--disable-features=TranslateUI,BlinkGenPropertyTrees',
    '--disable-ipc-flooding-protection',
    '--disable-renderer-backgrounding',
    '--enable-features=NetworkService,NetworkServiceInProcess',
    '--force-color-profile=srgb',
    '--hide-scrollbars',
    '--metrics-recording-only',
    '--mute-audio',
    '--headless',
    '--no-sandbox',
  ],
});

const driver = new webdriver.Builder()
  .forBrowser('chrome')
  .withCapabilities(chromeCapabilities)
  // Specify browserless for the server
  .usingServer('https://chrome.browserless.io/webdriver')
  .build();

(async () => {
  try {
    await driver.get('https://www.example.com/');

    // Take screenshot of results page. Save to disk.
    const base64png = await driver.takeScreenshot();
    fs.writeFileSync('.no-git/screenshot.png', new Buffer(base64png, 'base64'));
  } finally {
    driver.quit();
  }
})();

If you're using the hosted service, be sure to set the extra option for the browserless token:

Token Auth

chromeCapabilities.set('browserless:token', 'YOUR-API-TOKEN');

The reason you can't append use the standard ?token=YOUR-API-TOKEN is due to limitations in many of the Selenium libraries where query-string parameters are dropped from the server URL.
