With multiple cross-browser testing solutions available to you, it can be challenging to determine which platform is the right one for your product. While Selenium has been the de facto platform for years, Cypress and Playwright are prominent alternatives that are taking hold of the automated testing sphere and enabling dev teams to successfully test according to their specific needs.
If you are debating between Playwright vs. Cypress, Playwright vs. Selenium, or even Playwright vs. Cypress vs. Selenium, read on to learn more about each platform along with some insightful tips to help you discover the best cross-browser testing solution to lead your application to success.

Below we will take a deeper dive into the specifics of each testing platform, as well as a closer look at Selenium, the de facto automated testing tool for developers and engineering teams.
Microsoft Playwright, developed by the same team that brought you Puppeteer, is one of the growing trends in cross-browser testing solutions. While Playwright is comparable to Puppeteer in many respects, Playwright surpasses Puppeteer in its support capabilities for Chrome, WebKit, and Firefox browsers.
Additional capabilities of Playwright include:
With the recent launch of Cypress 10, additional features such as component testing, a migration assistant, and an updated UX and UI experience improve upon the already widely used testing solution.
Additional capabilities of Cypress include:
Selenium is the leading open-source web app testing framework that comprises Selenium WebDriver, Selenium IDE, and Selenium Grid. With this comprehensive set of testing tools, testers and developers can experience robust browser-based regression automation tests with language-specific support, the ability to scale and distribute scripts across environments, recording and playback of browser interactions on Chrome, Firefox, and Edge, and automated exploratory testing and bug recreation scripts, among other features.
This powerful platform remains the standard for many developers and testing teams due to its array of offerings, but platforms like Playwright and Cypress are taking hold of the testing sphere as complementary tools to Selenium – sometimes even replacing Selenium, depending on the testing requirements of an application.
So, which cross-browser platform is right for you?
Now that we have delved into the specifics of each automated testing platform, let us compare Playwright vs. Cypress vs. Selenium to gain a deeper understanding of which tool is the best solution for your situation.
While these two end-to-end testing platforms serve a similar end goal, Cypress and Playwright go about the testing process in different ways. Cypress is considered more of a “package offering” when compared to Playwright, as it generates a folder system with example files which can assist testing teams, though testers must work within the confines of the existing test runner framework.
Playwright on the other hand does not create files and enables you to choose your test runner framework. Playwright allows for greater flexibility than Cypress in this regard and supports multiple browsers.
When it comes to Playwright vs. Cypress, the right choice for you will be determined by the specific needs of your application and the level of flexibility vs. structure you require to run your automated tests.
Playwright and Selenium are both capable web testing solutions that perform similar functions with some differences in their feature offerings and architecture. Because Selenium has been around longer, it offers broad support for browsers and languages, and a plethora of support features. As a newcomer to the web testing scene, Playwright offers newer features that Selenium lacks and is specifically designed for modern web usage, running at high speeds even for more complex testing cases.
Selenium uses the WebDriver API to communicate between many different web browsers and drivers and operates by translating tests into JSON and sending them back to the browsers, which then send back an HTTP response.
In contrast, Playwright uses WebSocket rather than HTTP and WebDriver. WebSocket remains open for the duration of a test, keeping all interactions within one connection and thus increasing the speed of execution.
Due to its longevity, Selenium outperforms Playwright in its browser and languages support, though Playwright is quickly gaining traction in those arenas. Though Selenium is constantly in development to build new features, Playwright already offers capabilities that outshine Selenium in terms of speed, efficiency, and adaptability to the modern testing sphere.
Cypress can be said to be the more developer-focused framework when compared to Selenium, though Selenium still holds its status as the longest-running testing framework for good reason. Both testing tools excel in their operations and end results, while approaching testing in different ways.
Cypress has a more limited scope of integrations, but developers will not have to worry about configuring complex environments during setup.
While Selenium and Cypress provide a different angle on testing, both are excellent tools for achieving high-quality results.
Ultimately, deciding which cross-platform testing solution to utilize comes down to which features are the most important to your specific application and which testing approach best serves your product.
Regardless of whether you choose Playwright vs. Cypress vs. Selenium, Perfecto pairs perfectly with each of these cross-browser testing platforms, offering continuous end-to-end testing and support.
When paired with Perfecto, testers and developers can release high-quality apps with ease while experiencing the following benefits:
