Running Selenium with Headless Chrome Webdriver

selenium headless chrome python
run chrome headless selenium-java
headless chrome selenium c#
python selenium hide chrome browser
headless chrome download
headless chrome pdf
headless chrome screenshot
chrome headless print-to-pdf

So I'm trying some stuff out with selenium and I really want it to be quick.

So my thought is that running it with headless chrome would make my script faster.

First is that assumption correct, or does it not matter if i run my script with a headless driver?

Anyways I still want to get it to work to run headless, but I somehow can't, I tried different things and most suggested that it would work as said here in the October update

How to configure ChromeDriver to initiate Chrome browser in Headless mode through Selenium?

But when I try that, I get weird console output and it still doesn't seem to work.

Any tipps appreciated.

To run chrome-headless just add --headless via chrome_options.add_argument, i.e.:

from selenium import webdriver from selenium.webdriver.chrome.options import Options
chrome_options = Options()
#chrome_options.add_argument("--disable-extensions")
#chrome_options.add_argument("--disable-gpu")
#chrome_options.add_argument("--no-sandbox") # linux only
chrome_options.add_argument("--headless")
driver = webdriver.Chrome(options=chrome_options)
start_url = "https://duckgo.com"
driver.get(start_url)
print(driver.page_source.encode("utf-8"))
driver.quit()
# b'<!DOCTYPE html><html xmlns="http://www....

So my thought is that running it with headless chrome would make my script faster.

Try using chrome options like --disable-extensions or --disable-gpu and benchmark it, but I wouldn't count with much improvement.

Note: As of today, when running chrome headless on Windows., you should include the  --disable-gpu flag See crbug.com/737678

Running Selenium with Headless Chrome, To run chrome-headless just add --headless via chrome_options.add_argument , i.e.: from selenium import webdriver from  Now let’s begin configuring Selenium to work with headless Chrome. We’ll do this by first creating a ChromeOptions object that we can use to configure the options that will be passed to the WebDriver initializer. from selenium import webdriver options = webdriver.ChromeOptions()

If you are using Linux environment, may be you have to add --no-sandbox as well and also specific window size settings. The --no-sandbox flag is no needed on Windows if you set user container properly.

Use --disable-gpu only on Windows. Other platforms no longer require it. The --disable-gpu flag is a temporary work around for a few bugs.

//Headless chrome browser and configure
            WebDriverManager.chromedriver().setup();
            ChromeOptions chromeOptions = new ChromeOptions();
            chromeOptions.addArguments("--no-sandbox");
            chromeOptions.addArguments("--headless");
            chromeOptions.addArguments("disable-gpu");
//          chromeOptions.addArguments("window-size=1400,2100"); // Linux should be activate
            driver = new ChromeDriver(chromeOptions);

Running Selenium with Headless Chrome Webdriver, mode using PhantomJS, you first need to download the PhantomJS executable file and save it in a location, e.g. your project's resources folder. I recommend Running Selenium with Headless Chrome if you want the full instructions on how to set things up yourself, but I've dropped in some examples below to get you started. Using ChromeDriver.

from time import sleep

from selenium import webdriver
from selenium.webdriver.chrome.options import Options

chrome_options = Options()
chrome_options.add_argument("--headless")

driver = webdriver.Chrome(executable_path="./chromedriver", options=chrome_options)
url = "https://stackoverflow.com/questions/53657215/running-selenium-with-headless-chrome-webdriver"
driver.get(url)

sleep(5)

h1 = driver.find_element_by_xpath("//h1[@itemprop='name']").text
print(h1)

Then I run script on our local machine

It is working and it is with headless Chrome.

Running Selenium Tests With Chrome Headless, than real time browsers. Install chromeDriver and google-chrome-stable version on the linux server, where the tests will be triggered and add the same binaries in your code. Previously we have used HTMLUnitDriver and PhantomJS driver Run Selenium Test In Headless Mode. In case you are not familiar with Headless Mode then in just line I can say that “Test will run without GUI” it means test will be running in background and you will get the result after execution.

    options.add_argument("headless")
    options.add_argument("start-maximized")
    options.add_argument("window-size=1900,1080"); 
    driver = webdriver.Chrome(chrome_options=options, executable_path="/usr/bin/chromedriver")
    driver.get("https://www.example.com")
    html = driver.page_source
    print(html)

Comments
  • That's pretty much outdated, or what do you mean? Maybe I miss a point, could you clarify what you mean?
  • headless won't make it run noticeably faster
  • @CoreyGoldberg how so, do you have any sources?
  • you should benchmark both
  • @Rhynden What is the weird console output?
  • @AndroidNoobie the edit suggested by ukashima huksay is one that is implemented if I recall correctly may 2018. It finds its way now for getting rep. ukashima huksay should have mentioned it though. (From Review).
  • @ukashima huksay next time you find this chrome change mention it in a comment behind the change as I did a few weeks ago somewhere on a question. See also my previous comment above this one. (From Review).
  • chrome_options.headless = True also works
