Playwright
Overview
What Playwright is
Playwright is a framework for testing web apps the way a real user would: it opens a browser, clicks buttons, fills forms, and checks that the right things happen. Built by Microsoft, it controls Chromium, Firefox, and WebKit (Safari's engine) with a single API, and it works in TypeScript, JavaScript, Python, .NET, and Java.
How it works
Playwright auto-waits for elements to be ready before acting, which removes much of the flakiness that plagues older tools. It runs headless (no visible window) for speed in CI pipelines, supports parallel test execution, and captures screenshots, videos, and a trace viewer to debug failures. It can also mock network requests and test across mobile viewports.
Why it matters for your business
Automated end-to-end tests catch broken checkouts, forms, and logins before customers do, protecting revenue and reputation. Playwright is a common choice on frontend, full-stack, and Next.js or React development projects, wired into CI/CD so tests run on every code change. That safety net lets a team ship updates faster and with far more confidence.

FAQ
Playwright — common questions
Playwright vs Cypress: which is better?
Both are strong modern end-to-end tools. Playwright supports more browsers (including WebKit), multiple languages, and true parallelism, and it handles multi-tab and multi-origin flows more easily. Cypress has a mature developer experience and large community. Playwright is often preferred for cross-browser coverage and larger test suites.
Playwright vs Selenium?
Playwright is newer and generally faster and more reliable, with built-in auto-waiting, modern tooling, and simpler setup. Selenium is older, supports more languages and legacy browsers, and has a huge ecosystem. New projects often pick Playwright; Selenium persists where existing suites or broad language support demand it.
Is Playwright free?
Yes. Playwright is free and open-source under the Apache 2.0 license, maintained by Microsoft. There's no licensing cost; you only pay for the infrastructure, such as CI minutes, where your tests actually run.
