When it comes to web automation, Playwright and Selenium are two prominent tools. Each has unique strengths and is suited for different scenarios. In this blog we have discussed about Playwright vs Selenium which is better when it comes to web automation. We have compared them based on their features, use cases, and integration capabilities.

What is Playwright?
Playwright is a web automation library developed by Microsoft. It enables developers to write scripts that automate web interactions across multiple browsers, including Chromium, Firefox, and WebKit. Playwright is designed to provide reliable, fast, and capable browser automation, supporting modern web applications with features like auto-waiting for elements, parallel browser contexts, and cross-platform testing.
It integrates well with CI/CD pipelines and supports multiple programming languages, with primary support for JavaScript/TypeScript and additional support for Python, Java, and C#
Architecture:
- Uses a client-server model with WebSocket communication.
- Includes browser contexts for isolated sessions.
Workflow:
- Test scripts written in supported languages (JavaScript, Python, etc.) interact with the Playwright client.
- Commands are sent over WebSocket to the Playwright server running Node.js.
- The server controls browsers (Chromium, Firefox, WebKit) and manages interactions.
from playwright.sync_api import sync_playwright
with sync_playwright() as p:
browser = p.chromium.launch()
page = browser.new_page()
page.goto("http://example.com")
page.fill("input[name='q']", "Playwright vs Selenium")
page.press("input[name='q']", "Enter")
browser.close()
Pros and Cons
Pros:
- Modern features
- Auto-wait
- Easy integration
- Fast and reliable tests
Cons:
- Less language support compared to Selenium.
- Newer with a smaller community.
What is Selenium?
Selenium is an open-source tool for automating web browsers. It allows developers and testers to write scripts in various programming languages, such as Java, Python, C#, and more, to control and interact with web applications. Selenium supports multiple browsers (Chrome, Firefox, Safari, Internet Explorer) and provides a suite of tools, including Selenium WebDriver, Selenium Grid, and Selenium IDE.
It is widely used for functional and regression testing of web applications, known for its flexibility and extensive community support.
Architecture:
- Composed of WebDriver, client libraries, and browser drivers.
- WebDriver sends commands from the client to the browser via HTTP.
Workflow:
- Test scripts written in various languages (Java, Python, etc.) interact with the WebDriver.
- WebDriver communicates with browser drivers (e.g., ChromeDriver) to control browser actions.
- Browser drivers execute commands and return results to the WebDriver.
from selenium import webdriver
driver = webdriver.Chrome()
driver.get("http://example.com")
element = driver.find_element_by_name("q")
element.send_keys("Playwright vs Selenium")
element.submit()
Pros and Cons
Pros:
- Broad language support
- Extensive community proven
- Reliability
Cons:
- Requires more setup for Synchronization
- Older API design

FAQ's
It depends. Playwright offers modern features and better cross-browser support, while Selenium provides language flexibility and extensive community support. Choose based on your project needs.
Overall, Playwright is faster than Selenium, which is perfect for teams that need to test different platforms and browsers. For some projects, Selenium might be a better option due to its integration features and support for multiple languages.
Selenium’s main advantages include broad language support, a mature ecosystem, and compatibility with legacy systems.
Playwright simplifies the process of testing your website on any platform and in any browser. Verify that your app functions for every user by testing it in every browser. You can set up projects in your config file by naming them and specifying the browser or device to be used.
