How it works
Playwright drives browsers from code: open a page, click, type, wait for responses and check what appears. Its test runner, Playwright Test, runs tests in parallel across browsers and emulated devices, waits for elements automatically (which cuts down flaky tests), and records traces with screenshots, network logs and a timeline you can step through after a failure.
It was built by the team that created Puppeteer at Google before moving to Microsoft, and it supports JavaScript and TypeScript, Python, Java and .NET. Codegen writes a test while you click through the site, UI mode shows tests running live, and a Playwright MCP server lets AI agents control a browser. Beyond testing, it is widely used for scraping, screenshots and PDFs.
Playwright pros and cons
Pros
- Tests Chromium, Firefox and WebKit with one API
- Auto-waiting and traces make failures easier to debug
- Parallel runs and sharding are built in and free
- Works from TypeScript, Python, Java and .NET
Cons
- Browser downloads make installs and CI images larger
- A broad API with more to learn than simple scripting tools
- Emulates mobile browsers but cannot test native mobile apps
When to use Playwright
Pick it when
- End-to-end tests for web apps across all major browser engines
- Checking WebKit (Safari) behaviour from Windows or Linux
- Teams that want parallel runs in CI without a paid service
Skip it when
- Native Android or iOS apps, which need mobile testing tools
- Pure logic tests, where Vitest, Jest or pytest are faster
