Introduction
Automation testing has become a crucial aspect of modern software development, enabling teams to ensure faster and more reliable application releases. Over the years, various testing tools have emerged, with Selenium being the industry standard for a long time. However, with evolving web technologies, newer tools like Playwright are gaining traction for their speed, reliability, and ease of use.
Developed by Microsoft, Playwright is an open-source automation framework designed to provide a seamless testing experience across multiple browsers and platforms. In this blog, we will explore what Playwright is, how it works, its advantages and disadvantages, and how it compares with Selenium and Cypress. We will also look at some MNCs that are leveraging Playwright for automation.
What is a Playwright?
Playwright is an end-to-end automation framework that supports Chromium, Firefox, and WebKit with a single API. It allows testers and developers to write reliable tests for modern web applications. Unlike traditional automation tools, Playwright provides cross-browser support without requiring separate configurations.
It is designed for high performance, offering parallel execution, automatic waiting mechanisms, and built-in debugging capabilities. Additionally, Playwright supports multiple programming languages, including JavaScript, TypeScript, Python, Java, and C#, making it accessible to a wider audience of testers and developers.
How Playwright Works?

Playwright operates by directly interacting with browsers using the Dev Tools Protocol, eliminating the need for WebDriver, which traditional tools like Selenium rely on. This direct communication makes the Playwright faster and more efficient. It supports both headless and headed execution, enabling users to run tests in a graphical interface or in the background for better performance.
One of its standout features is auto-waiting, which means Playwright automatically waits for elements to be visible, clickable, or stable before interacting with them, reducing flaky test failures. Other advanced features include network interception, tracing, and debugging tools, making it a powerful choice for modern test automation.
Advantages of Playwright
Playwright offers several advantages that make it a preferred choice for automation:
Cross-browser testing with a single API – Unlike Cypress, which supports only Chromium-based browsers, Playwright works with Chromium, Firefox, and WebKit.
Multiple programming language support – Playwright supports JavaScript, TypeScript, Python, Java, and C#, making it accessible for teams with diverse technical expertise.
Faster execution compared to Selenium – Since Playwright communicates directly with browsers instead of using WebDriver, it reduces test execution time.
Built-in auto-waiting mechanism – This eliminates the need for explicit waits, reducing flaky test failures.
Parallel test execution – Playwright allows running tests in parallel without requiring an external setup like Selenium Grid.
Powerful debugging tools – Features like Playwright’s Trace Viewer provide detailed insights into test executions, making it easier to debug failures.
Disadvantages of Playwright
Despite its powerful features, Playwright has some limitations:
Limited community support compared to Selenium – Since Playwright is relatively new, its community resources and third-party integrations are still growing.
Not ideal for mobile app automation – Unlike Appium, Playwright does not natively support mobile applications. However, it can be used for mobile browser testing.
Learning curve for testers migrating from Selenium or Cypress – Testers who have been using Selenium or Cypress may need some time to adapt to Playwright’s syntax and API.
How Playwright is Different from Other Automation Tools
Automation testing tools like Selenium, Cypress, Puppeteer, and WebDriver IO have been widely used. However, Playwright introduces several unique features that set it apart from these tools. Let’s explore how playwrights differ from them.
Playwright vs Selenium: Selenium has been the industry standard for web automation for years, but Playwright offers improvements in performance and reliability. Selenium uses WebDriver, which indirectly communicates with the browser, making it slower. In contrast, Playwright interacts with the browser directly through the Devtools Protocol, making it much faster. Playwright supports parallel execution by default, whereas Selenium requires a Selenium Grid setup. Additionally, Playwright includes an auto-wait mechanism, which waits for elements to appear before interacting with them, reducing flaky test failures.
Selenium supports real mobile testing via Appium, while Playwright supports mobile browser testing but not real devices. Another major difference is cross-browser support while Selenium supports all major browsers, Playwright supports Chromium, Firefox, and WebKit with a single API, making it more efficient for multi-browser testing.
Playwright vs Cypress: Cypress is known for its simplicity and fast execution, but it has several limitations when compared to Playwright. The biggest drawback of Cypress is that it only supports Chromium-based browsers and lacks true cross-browser testing capabilities. Playwright, on the other hand, supports Chromium, Firefox, and WebKit. Another limitation of Cypress is that it does not support multiple tabs and windows, whereas Playwright handles multiple browser contexts effortlessly.
Cypress is restricted to JavaScript, while Playwright supports JavaScript, TypeScript, Python, Java, and C#, making it more versatile for different development teams. Playwright also provides better network interception capabilities, allowing users to manipulate network requests and responses more effectively than Cypress. Additionally, Playwright’s headless mode is highly optimized, whereas Cypress's headless execution is slower.
Playwright vs Puppeteer: Puppeteer, developed by Google, is a browser automation tool similar to Playwright, but it only supports Chromium-based browsers. In contrast, Playwright supports Chromium, Firefox, and WebKit, making it more suitable for cross-browser testing. Puppeteer lacks an auto-wait mechanism, meaning users must manually implement waits for elements to be ready, whereas Playwright automatically waits for elements to appear before performing actions.
Another major advantage of Playwright is its parallel execution capability, which Puppeteer does not have built in. Playwright also includes an advanced Trace Viewer for debugging, making it easier to analyze and fix test failures.
Playwright vs WebDriver IO: WebDriver IO is built on top of Selenium but provides additional integrations. While WebDriver IO supports all major browsers, it relies on WebDriver, making it slower than Playwright. WebDriver IO requires additional configuration for parallel execution, whereas Playwright supports parallel testing natively. Playwright also offers better headless execution performance and network interception features, which WebDriver IO lacks.
Why Choose Playwright Over Other Tools?
Playwright stands out due to its faster execution, cross-browser support, built-in auto-wait mechanisms, and native parallel execution. It supports multiple programming languages and allows full control over browser contexts, making it ideal for modern web automation. Compared to Selenium, Playwright is faster and more reliable. Compared to Cypress, it offers true cross-browser testing and multi-tab support. Compared to Puppeteer, it supports more browsers and better debugging tools.
Which MNCs Use Playwright?
Many multinational companies (MNCs) and tech giants have adopted Playwright for their automation testing needs due to its speed, reliability, and cross-browser support. Some of the well-known MNCs using Playwright include:
Microsoft: Being the creator of Playwright, Microsoft extensively uses it for testing its web applications, including Office 365, Azure, and Edge browser testing.
