How to execute Selenium Chrome WebDriver in silent mode?

Question

When using Chrome Selenium-WebDriver, it will output diagnostic output when the servers are started:

Started ChromeDriver (v2.0) on port 9515

Answer 1

For me the only thing that worked for

   selenium-chrome-driver-2.48.2.jar
   chromedriver 2.20
   selenium-java-2.48.2.jar

was

   ChromeOptions options = new ChromeOptions();
   System.setProperty("webdriver.chrome.args", "--disable-logging");
   System.setProperty("webdriver.chrome.silentOutput", "true");
   driver = new ChromeDriver(options);

Answer 2

To run Chrome browser with Selenium in console in completely silent mode, you should use this snippet:

options = Options()
options.headless = True
options.add_experimental_option("excludeSwitches", ["enable-logging"])

That trick will suppress any console message from either the Selenium driver or the browser itself, including the first message DevTools listening on ws://127.0.0.1 at the very start.
