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('chromeOptions', {
  args: ['--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('chromeOptions', {
  args: ['--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.
