Is Playwright free to use?
Yes. Playwright is completely free and open-source under the Apache 2.0 license. There are no paid tiers, premium features, or usage limits. All capabilities including cross-browser testing, trace viewer, code generator, and parallel execution are available at no cost.
How does Playwright compare to Cypress?
Playwright supports Chromium, WebKit, and Firefox natively, while Cypress primarily targets Chromium-based browsers. Playwright offers multi-language support (Python, .NET, Java) whereas Cypress is JavaScript-only. Playwright also supports multi-tab and multi-origin testing in a single test, which Cypress cannot do.
What programming languages does Playwright support?
Playwright provides official APIs for TypeScript, JavaScript, Python, .NET (C#), and Java. Each language binding offers the same core capabilities including auto-waiting, assertions, and browser context isolation.
How does Playwright handle flaky tests?
Playwright uses auto-waiting, which means it automatically waits for elements to be actionable before interacting with them. Web-first assertions automatically retry until conditions are met or a timeout is reached. This eliminates most causes of test flakiness without manual waits or sleeps.
Can Playwright test mobile web applications?
Playwright includes native mobile emulation for Chrome on Android and Mobile Safari. It can simulate device viewports, touch events, geolocation, and other mobile-specific capabilities. However, it does not test native mobile apps — only web content rendered in mobile browsers.
What is the Playwright Trace Viewer?
The Trace Viewer is a built-in debugging tool that records a complete trace of test execution including DOM snapshots at every step, screencast video, network requests, and console logs. You can step through test actions and inspect the exact page state at any point, making it straightforward to diagnose failures.
