In the world of software, the word headless by itself usually implies the absence of a presentation layer (GUI) from the application at hand. Accordingly, a headless browser is a browser instance without any visible GUI (graphical user interface) elements. Headless browsers have become increasingly important as web applications have grown more complex. This growing complexity drove the need for new tools to facilitate tasks like web automation, testing, web scraping and other server-side browser interactions. In this article, we will dive deeper into what is a headless browser, what are its use cases, and what are some common tools that utilize the power of headless browsers. ## Key Takeaways Understand what is a headless browser for automation, testing, and web scraping, exploring top tools like Selenium, Playwright, and Puppeteer. - Use headless browsers for web automation tasks without GUI overhead for better performance and server deployment - Apply headless browsers for E2E testing, web scraping, and automated task execution in CI/CD pipelines - Choose between Selenium for stability, Playwright for modern features, or Puppeteer for Node.js environments - Implement headless browser automation for JavaScript-heavy websites that require dynamic content rendering - Leverage programmatic control capabilities for repetitive tasks and large-scale data collection operations - Optimize resource usage by running headless browsers on servers without display requirements **Get web scraping tips in your inbox**Trusted by 100K+ developers and 30K+ enterprises. Unsubscribe anytime. ## What Is a Headless Browser? A headless browser is a web browser **stripped of all GUI elements**, leaving us with the core web browsing functionalities like rendering web content, navigating webpages, managing cookies, network communication and much more. Headless browsers can be controlled via command line or programmatically through a wide range of programming languages, making it very versatile and useful. This makes headless browsers a perfect match to run on servers, as they typically don’t support rendering any visual output and are also controlled via command line. Headless browsers are also significantly faster and more efficient than the traditional browser you are reading this article through. By avoiding the resource-intensive process of drawing output on a screen, a headless browser is able to dedicate all its resources into network communication and rendering content. ## Headless Browser Use Cases The performance, efficiency, and programmatic control capabilities of headless browsers make them a great tool to perform repetitive tasks like end-to-end testing, automation, and web scraping. ### E2E Testing E2E testing is a crucial step in an application’s lifecycle. It involves **simulating user interactions** with an application’s frontend programmatically, ensuring all user flows within a complex app behave correctly. These simulated interactions don’t always require any visual output and typically run in CI/CD pipelines which makes them a very obvious candidate to implement using headless browsers. ### Automation Extending the E2E testing use case, simulating interactions programmatically within an application is also very useful for **automating repetitive tasks** that might take weeks or months and tens or hundreds of employees to perform manually. For example, submitting hundreds of thousands of records to a web form that you don’t have direct access to the endpoint it submits its data to can be a tedious task to do manually, but using a headless browser and some computing resources could turn it into about an hour’s worth of work. ### Web Scraping Now for the star of the show, the most popular use case for headless browsers, **web scraping**. The popularity of dynamic webpages (also usually referred to as single-page applications or client-side rendered applications) has made web scraping with a headless browser a necessity. As those applications rely on JavaScript to render any HTML to the page, simply sending a **GET request** to the page’s URL and parsing the HTML received doesn’t work anymore. Using a headless browser for scraping allows the page to **load and execute** any JS code that ships with the initial HTML document, resulting in HTML content which can then be parsed and accessed programmatically to extract structured data from. [How to Scrape Dynamic Websites Using Headless Web BrowsersIntroduction to using web automation tools such as Puppeteer, Playwright, Selenium and ScrapFly to render dynamic websites for web scraping](https://scrapfly.io/blog/posts/scraping-using-browsers) ## Common Headless Browser Tools It is no surprise that the most common tools that leverage the capabilities of headless browsers are browser automation tools. Browser automation tools are mostly marketed as testing automation tools. However, they are perfect to use for regular automation tasks and most importantly web scraping. The most popular and widely-used browser automation tools are: 1. Playwright 2. Puppeteer 3. Selenium 4. Selenium-Wire 5. Undetected Chromedriver ### Playwright [Playwright](https://playwright.dev/) is relatively new (initial release 2020) open-source browser automation library created by Microsoft. It has gained a lot of popularity lately due to its intuitive API design that overcomes a lot of limitations in other popular libraries like Selenium and Cypress. It supports all modern browser engines and runs in both headed and headless modes. Playwright was, as per its [documentation](https://playwright.dev/), "created specifically to accommodate the needs of end-to-end testing" yet it is widely used by the web scraping community to build headless browser bots that extract data from dynamic websites. **Supported languages:** [Python](https://playwright.dev/python/docs/intro), [JS](https://playwright.dev/docs/intro), [Java](https://playwright.dev/java/docs/intro),[.NET](https://playwright.dev/dotnet/docs/intro) **Pros:** - **Multi-Browser Support**: Supports Chromium, Firefox, and WebKit, which covers most browser engines. - **Cross-Platform**: Works on Windows, macOS, and Linux, and supports multiple languages like JavaScript, Python, and C#. - **Advanced Features**: Provides powerful features like intercepting network requests, [taking screenshots](https://scrapfly.io/screenshot-api) (see [best screenshot APIs](https://scrapfly.io/blog/posts/what-is-the-best-screenshot-api)), generating PDFs, and simulating geolocation. - **DevTools Protocol**: Uses the DevTools protocol, enabling direct control over browser features. **Cons:** - **Larger API Surface**: The API is more extensive compared to some other tools, leading to a steeper learning curve. - **Relatively New**: Less community support and third-party integrations compared to more established tools like Selenium. Here is an example code that uses Playwright and [Parsel](https://pypi.org/project/parsel/) in python to scrape some products from [web-scraping.dev](https://web-scraping.dev) python```python from playwright.sync_api import sync_playwright from parsel import Selector with sync_playwright() as pw: browser = pw.chromium.launch(headless=True) context = browser.new_context(viewport={"width": 1920, "height": 1080}) page = context.new_page() page.goto("https://web-scraping.dev/products") # go to url page_html = page.content() sel = Selector(text=page_html) parsed = [] for product in sel.css(".product"): parsed.append({ 'name': product.css('h3::text').get(), 'short_description': product.css('.short-description::text').get(), 'url': product.css('h3 a::attr(href)').get(), 'price': product.css('.price::text').get(), "image_url": product.css('img::attr(src)').get() }) ``` [Web Scraping with Playwright and PythonPlaywright is the new, big browser automation toolkit - can it be used for web scraping? In this introduction article, we'll take a look how can we use Playwright and Python to scrape dynamic websites.](https://scrapfly.io/blog/posts/web-scraping-with-playwright-and-python) ### Puppeteer [Puppeteer](https://pptr.dev/) is another open-source browser automation library built by Google. Puppeteer is widely used in the JS community for automation and web-scraping tasks. It is not as popular as other tools due to it being only available in JS and supporting only Chrome and Firefox browsers. **Supported languages:** [JS](https://pptr.dev/), [Python](https://github.com/pyppeteer/pyppeteer) (unofficial and unmaintained) **Pros:** - **Native Chromium Support**: Puppeteer is developed by Google and provides native control over Chromium-based browsers, which leads to better stability. - **Simpler API**: Easy to learn and use due to its straightforward API. - **Network Control**: Supports features like request interception, network throttling, and custom headers. - **Good Documentation**: Well-documented and actively maintained by the developers. **Cons:** - **Webkit Support**: Lacks support for Webkit browsers like Safari - **Limited Language Support**: Primarily supports JavaScript and TypeScript, with no official bindings for other languages. Here is an example that uses Puppeteer and [Cheerio](https://cheerio.js.org/) in Node.js to scrape the same products we scraped using Playwright javascript```javascript const puppeteer = require("puppeteer"); const cheerio = require("cheerio"); (async () => { const browser = await puppeteer.launch({ headless: true }); const page = await browser.newPage(); await page.setViewport({ width: 1920, height: 1080 }); await page.goto("https://web-scraping.dev/products"); const pageHtml = await page.content(); const $ = cheerio.load(pageHtml); const parsed = []; $(".product").each((index, element) => { parsed.push({ name: $(element).find("h3").text().trim(), short_description: $(element).find(".short-description").text().trim(), url: $(element).find("h3 a").attr("href"), price: $(element).find(".price").text().trim(), image_url: $(element).find("img").attr("src"), }); }); console.log(parsed); await browser.close(); })(); ``` [How to Web Scrape with Puppeteer and NodeJS in 2026Introduction to using Puppeteer in Nodejs for web scraping dynamic web pages and web apps. Tips and tricks, best practices and example project.](https://scrapfly.io/blog/posts/web-scraping-with-puppeteer-and-nodejs) ### Selenium [Selenium](https://www.selenium.dev/documentation/) is one of the most popular and widely-used browser automation tools. Dating back to 2004, selenium has had its opportunity to gather a huge ecosystem of plugins around it and an unprecedented community support. Selenium can be used with almost any programming language and all web browsers including good old Internet Explorer, giving it an edge compared to any other browser automation library. **Supported languages:** [Python](https://selenium-python.readthedocs.io/), [JavaScript](https://www.npmjs.com/package/selenium-webdriver), [Java](https://www.selenium.dev/selenium/docs/api/java/index.html), [C#](https://www.nuget.org/packages/Selenium.WebDriver), [PHP](https://github.com/php-webdriver/php-webdriver), [Go](https://pkg.go.dev/github.com/tebeka/selenium), [Dart](https://pub.dev/packages/webdriver), [R](https://docs.ropensci.org/RSelenium/), [Ruby](https://rubygems.org/gems/selenium-webdriver/versions/4.23.0), [Perl](https://github.com/teodesian/Selenium-Remote-Driver), [Haskell](https://hackage.haskell.org/package/webdriver), [Objective-C](https://github.com/appium-boneyard/selenium-objective-c) and more. **Pros:** - **Cross-Browser and Cross-Platform**: Supports all major browsers (Chrome, Firefox, Safari, Edge, Opera) and platforms (Windows, Linux, macOS). - **Large Community and Ecosystem**: Extensive community support, libraries, and tools built around Selenium. - **Extensive Documentation**: Comprehensive documentation and a large number of learning resources. **Cons:** - **Slower Execution**: Generally slower than Playwright or Puppeteer due to its architecture and reliance on WebDriver protocol. - **Manual Waiting**: Often requires manual handling of waits for elements to load, which can lead to flakiness in tests. - **Limited Features for Modern Web Apps**: Lacks some advanced features such as built-in support for intercepting network requests or mocking responses. Here is an example that uses Selenium and Parsel in Python to scrape the same data from the examples above: python```python from selenium import webdriver from selenium.webdriver.chrome.options import Options from parsel import Selector options = Options() options.add_argument("--headless=new") options.add_argument("--window-size=1920,1080") driver = webdriver.Chrome(options=options) driver.get("https://web-scraping.dev/products") page_html = driver.page_source sel = Selector(text=page_html) parsed = [] for product in sel.css(".product"): parsed.append({ "name": product.css("h3::text").get(), "short_description": product.css(".short-description::text").get(), "url": product.css("h3 a::attr(href)").get(), "price": product.css(".price::text").get(), "image_url": product.css("img::attr(src)").get(), }) print(parsed) driver.quit() ``` Selenium’s long-running development and support for multiple languages and browsers might have significant benefits but it also brings to the table a lot of limitations. Its API is outdated and developer experience is not very intuitive, it doesn’t support modern language features and browser APIs. That’s why other tools like Playwright and Puppeteer might be better alternatives. [Web Scraping with Selenium and PythonIntroduction to web scraping dynamic javascript powered websites and web apps using Selenium browser automation library and Python.](https://scrapfly.io/blog/posts/web-scraping-with-selenium-and-python) ### Selenium-Wire and Undetected Chromedriver Scrapfly #### Scale your web scraping effortlessly Scrapfly handles proxies, browsers, and anti-bot bypass — so you can focus on data. [Try Free →](https://scrapfly.io/register)Selenium’s popularity undoubtedly extends to the web scraping community as it also supports running in headless mode. This popularity has also set the ground for developers to build extensions that solve problems that are not directly addressed in selenium’s core automation library, such extensions include Selenium-Wire and Undetected Chromedriver. #### 1. Selenium-wire [Selenium-wire](https://pypi.org/project/selenium-wire/) is a Python library that extends selenium's headless browser library. It adds to selenium the ability to inspect and manipulate background http requests sent by the browser. This adds another dimension to web scraping with headless browsers as we can now intercept HTTP requests invoked by users' interactions and extract valuable data from them. Here is an example for intercepting testimonial requests on the web-scraping.dev testimonials pages python```python from seleniumwire import webdriver from parsel import Selector import time options = webdriver.ChromeOptions() options.add_argument("log-level=3") # disable logs driver = webdriver.Chrome(options=options) driver.get("https://web-scraping.dev/testimonials") def scroll(driver: webdriver): for i in range(0, 5): driver.execute_script("window.scrollTo(0, document.body.scrollHeight);") time.sleep(1) scroll(driver) def parse_xhr_html(html: str): """parse review data from each xhr response body""" data = [] selector = Selector(html) for review in selector.css("div.testimonial"): data.append({ "rate": len(review.css("span.rating > svg").getall()), "text": review.css("p.text::text").get() }) return data # iterate over all the recorded XHR requests and parse each response body data = [] for request in driver.requests: if "/testimonials" in request.url: xhr_data = parse_xhr_html(request.response.body.decode('utf-8')) data.extend(xhr_data) driver.quit() ``` You can learn more about selenium-wire in our dedicated selenium-wire article: [Selenium Wire Tutorial: Intercept Background RequestsIn this guide, we'll explore web scraping with Selenium Wire. We'll define what it is, how to install it, and how to use it to inspect and manipulate background requests.](https://scrapfly.io/blog/posts/how-to-intercept-background-requests-with-selenium-wire) #### 2. Undetected Chromedriver Many websites have implemented measures that detect headless browser bots and scrapers and block them from accessing the website's pages. *Enters* [*Undetected Chromedriver*](https://pypi.org/project/undetected-chromedriver/). Undetected Chromedriver is a modified Selenium webdriver that has built-in measures to combat websites that block automated headless browsers scraping their pages. Here is an example for using undetected chromedriver to bypass Cloudflare's crawler block python```python import undetected_chromedriver as uc import time # Add the driver options options = uc.ChromeOptions() options.headless = False # Configure the undetected_chromedriver options driver = uc.Chrome(options=options) with driver: # Go to the target website driver.get("https://nowsecure.nl/") # Wait for security check time.sleep(4) # Take a screenshot driver.save_screenshot('screenshot.png') # Close the browsers driver.quit() ``` Learn how to use selenium's undetected chromedriver through our dedicated blogpost [Web Scraping Without Blocking With Undetected ChromeDriverIn this tutorial we'll be taking a look at a new popular web scraping tool Undetected ChromeDriver which is a Selenium extension that allows to bypass many scraper blocking techniques.](https://scrapfly.io/blog/posts/web-scraping-without-blocking-using-undetected-chromedriver) ## Cloud Browsers with ScrapFly API Choosing the right browser automation tool for your specific use case is a hard decision. That's why we at Scrapfly are offering to do the heavy lifting for you by providing a generic, scalable and fully managed cloud-based browser automation API. Scrapfly service does the heavy lifting for you!Here's how easy it is to start and control a cloud browser with Scrapfly and Python: python```python from scrapfly import ScrapflyClient, ScrapeConfig client = ScrapflyClient(key='Your Scrapfly Key') api_result = client.scrape(ScrapeConfig( url="https://web-scraping.dev/login", # enable js render_js=True, # optionally - send browser actions to reach the pages you want scraped js_scenario = [ {"fill": {"selector": "input[name=username]", "value":"user123"}}, {"fill": {"selector": "input[name=password]", "value":"password"}}, {"click": {"selector": "button[type='submit']"}}, {"wait_for_navigation": {"timeout": 5000}} ], )) print(api_result.selector.css("#secret-message ::text").get()) # prints: "🤫" ``` Not only can you render JavaScript, but you can fully control the browser with instructions like button clicking, scrolling, and text input! ## FAQ What is a headless browser?A headless browser is a web browser without a graphical user interface, designed to run in environments without displays. It performs all the functions of a regular browser: rendering web pages, executing JavaScript, and handling network requests. However, it operates invisibly in the background. What is the best headless browser automation tool?Every tool has its pros and cons. However, Playwright has been gaining a lot of interest lately due to its feature-rich, cross-language, cross-browser API which provides both asynchronous and synchronous client implementations. What is a dynamic web application?A dynamic web application, also referred to as single page application or client side rendered application, is a type of web application that depends on JavaScript libraries and frameworks to render all or part of its content. This means that the HTML that loads when the website is requested doesn't have any content which makes scraping using traditional methods impossible. What is the difference between a headless browser and a normal browser?A headless browser runs without a visible graphical interface and is usually controlled by code. A normal browser displays windows and accepts direct user input. Both can use the same browser engine, execute JavaScript, manage cookies, and render pages. The main difference is the interface and the control method. What is an example of a headless browser?Headless Chromium controlled through Playwright or Puppeteer is the most common example. Firefox can also run headlessly, and Selenium can automate Chrome, Firefox, or Edge without opening a visible window. Is Firefox a headless browser?Firefox is a regular browser that can run in headless mode. Developers can start it with its headless option or control it through frameworks such as Playwright or Selenium. It still uses Firefox's Gecko engine; it simply runs without displaying a browser window. Is headless mode faster?Headless mode can reduce graphical-interface overhead, but it does not eliminate page rendering, JavaScript execution, network waits, or DOM work. It is often somewhat faster and lighter for automation, although page complexity and network latency usually matter more than whether the browser window is visible. ## Summary In this article, we have covered all the ins and outs of headless browsers and their use cases, as well as the popular tools that utilize headless browsers for testing, automation, and web scraping. The concept of a headless browser might seem simple but the ecosystem around it is definitely much more complex especially when it comes to scaling it to high volumes. This is why at Scrapfly, we hold the responsibility of building the data collection infrastructure that scales to your needs.
