What is the difference between Cypress and Playwright?
Updated 2 min read7 differences
In short
Cypress runs end-to-end tests inside the browser with an interactive runner, while Microsoft's Playwright drives browsers from outside, in several languages.
Cypress
Cypress is a JavaScript framework that runs end-to-end and component tests for web apps inside the browser, with automatic waiting and an interactive runner.

Playwright is Microsoft's open-source framework for end-to-end testing and browser automation, driving Chromium, Firefox and WebKit through one API.

The difference, explained
Both automate real browsers for end-to-end testing and wait for elements automatically, which makes tests far less flaky than older tools. Cypress, released in 2017, runs the test code in the same browser as the application. Playwright, released by Microsoft in 2020 by engineers who had worked on Puppeteer, drives Chromium, Firefox and WebKit from a separate process.
That architecture explains most differences. Running inside the browser gives Cypress direct access to the app and an excellent interactive runner with snapshots of every step, but it limits tests to one tab and needs special handling for multiple domains. Playwright can open several tabs, browser contexts and users in one test, test across origins freely and emulate mobile devices.
Cypress tests are written in JavaScript or TypeScript; Playwright supports JavaScript, TypeScript, Python, Java and .NET. Playwright runs tests in parallel and shards them across machines for free, and its trace viewer records everything for debugging failures in CI. Cypress offers parallelization and analytics through its paid Cypress Cloud service.
A common misconception is that one is simply better. Many front-end teams love Cypress's developer experience and component testing; Playwright has become the more common choice for new projects because of its flexibility, speed and browser coverage. Both are free and open source at their core.
Which one should you use?
Choose Cypress when…
- Your team values a very friendly interactive test runner.
- You focus on single-page apps and component testing.
- You already have a working Cypress suite.
Choose Playwright when…
- You need multiple tabs, users or domains in one test.
- You want to write tests in Python, Java or .NET.
- You want free parallel runs and wide browser coverage in CI.
Readers ask
Is Playwright replacing Cypress?
Playwright has grown quickly and is chosen for many new projects, but Cypress remains widely used and actively developed. Both are good choices.
Which is faster?
Playwright is usually faster for large suites because it runs tests in parallel by default. For a single test, the difference is small.
Can Cypress test Safari?
Cypress supports WebKit, the engine behind Safari, as an experimental option. Playwright supports WebKit as a standard browser.
