Popularity and Community Adoption
Selenium's Established Presence
For well more than ten years, Selenium has been used as one of the most popular frameworks developed for browser automation. It has a huge user base, a large community, more than enough documentation to learn from, as well as active contributors.
When the project is legacy with true compatibility and stability restrictions on browser versions, Selenium is a great selection.
Selenium's Ecosystem: Selenium-based tests can have integration with most of the existing CI's available today; i.e. Jenkins, CircleCI, TestNG, and this makes Selenium as one of the stronger options as it pertains to cross-browser automation.
Playwright's Rapid Growth
Playwright is a new option, yet it's rapidly growing with modern features that are optimized for developer contribution. Developers are attracted to the speed of execution, its lightweight design, and even easier integration into modern CI/CD pipelines.
Playwright's growing Ecosystem: Playwright is developing a solid ecosystem with Playwright Test, a testing framework, and Docker support, which will make it the best fit for modern web applications.
Key Features and Technical Comparison
Chromium, Firefox, WebKit
Java, Python, C#, Ruby, etc.
JavaScript, TypeScript, Python
Requires third-party tools
Selenium: Selenium WebDriver can be quite slow and can be painfully slow when testing JavaScript-heavy applications. Selenium has shortcomings when dealing with asynchronous behavior which can create flaky tests.
Playwright: Playwright performs better because it speaks directly to the browser itself. Playwright always runs in headless mode by default, and has a modern development architecture that is better for single-page applications (SPAs).
Ease of Use and Debugging
Selenium: With Selenium, the developer has to manually setup the testing and create training sessions for third parties to debug. For developers who understand selenium, it works, but for developers who do not, it can be a bit painful to get the hang of.
Playwright: Playwright has useful debugging tools built-in: auto-waits for elements, trace viewer, built-in video recording support, auto-retry for tests, etc. Each of these features help developers identify issues more easily, create tests more smoothly, and improve developer satisfaction or happiness.
Cross-Browser and Language Support
Selenium: Selenium has a wide breadth of support to many browsers and programming languages that it is very well-suited for cross-browser testing!
Playwright: While Playwright can comfortably work with Chromium, Firefox and WebKit, it tends to favor modern web apps. Its native support for Javascript and Typescript ideally suits people developing using these languages, but there is also Python and C# support.
Selenium: The Selenium ecosystem is mature, and is also well-supported by mobile testing tools like Appium, test management tools like TestNG and containerization like Docker. The only difficulty is linking these integrations together sometimes it is very time-consuming.
Playwright: The ecosystem surrounding Playwright is rapidly developing, and Playwright Test has many "out of the box" features such as running tests in parallel to save time and automatic retrying of failed tests. It is now even easier to integrate into modern CI/CD pipelines.
Use Cases and Suitability
Legacy applications that need to be tested across a variety of browsers.
Compatibility with older browsers (e.g., Internet Explorer) is crucial.
When testing across multiple languages and platforms, or when evaluating differences like system testing vs integration testing, Selenium provides a stable ecosystem.
If your team is already familiar with Selenium's ecosystem.
When to Choose Playwright
When building modern web applications or single-page applications (SPAs) that need to be end-to-end tested quickly and reliably.
When the goal is speed as a value over all else, and to be able to debug, and in parallel.
When your team primarily develops in a JavaScript/TypeScript environment.

Best Practices for Choosing the Right Tool
Evaluate the Project's Requirements:
If you're testing legacy applications that require broad browser compatibility**,** including older browsers, Selenium is the better option.
If you are testing modern web applications (especially single-page applications (SPAs)), Playwright is a better option due to its faster execution and the support of modern web capabilities.
If your team already has knowledge of Selenium, it may be better to stay on Selenium, especially if you're working within a substantial existing ecosystem.
If you are working in a JavaScript/TypeScript environment, Playwright is usually the better option because of its seamless transition into these languages.
Playwright is a growing ecosystem, and with features such as network request interception and headless mode by default, it is a good option for modern web applications.
For mobile web apps and web automation Playwright is modern, faster, and focused on browser automation.
Future-Proofing Your Tests:
Playwright has a developed ecosystem and supports many cutting-edge features with network request interception and headless mode for all browsers out of the box, making it a viable choice for next-gen web apps.
Selenium is still the leading tool for cross browser compatibility testing and for a large number of legacy projects, although it requires more setup (especially when integrating this with CI/CD pipelines).
If test execution in parallel is an important part of your workflow, Playwright Test is capable of this out of the box, while selenium can deploy tests across multiple machines through Selenium Grid but needs configurations to setup.
Integration with CI/CD Pipelines:
Both Playwright and Selenium integrate easily with CI/CD tools such as Jenkins, GitLab CI, and CircleCI but Playwright's native test framework can ease the CI/CD process and fit into modern DevOps workflows.
Both Playwright and Selenium are powerful tools for browser automation, but each excels in different areas. Selenium is still the gold standard for legacy testing and cross-browser compatibility, while Playwright offers a faster, modern approach for testing single-page applications and modern web technologies.
Choosing the right tool depends on your project’s needs, your team’s expertise, and the complexity of the web applications you are testing.
