Key differences
Browser support
Playwright runs against Chromium, Firefox, and WebKit. This makes it a strong choice when you need to exercise the same flow across browser engines, including WebKit for Safari-like coverage. Puppeteer supports Chrome and Firefox. It remains a good fit when your automation is centered on Chrome and you do not need WebKit coverage.Testing features
Playwright is available as both a browser automation library and the Playwright Test framework. Playwright Test includes parallel execution, fixtures, web-first assertions, retries, reporting, and trace collection. Its locators wait for elements to meet actionability checks before performing actions, which reduces the need for explicit waits. Puppeteer provides the browser automation layer. You can combine it with a test runner and assertion library that match your existing stack. This can be useful when you want a smaller automation-focused API or already have testing infrastructure in place.API and migration
The tools use similar concepts such as browsers, pages, selectors, and network interception, so many scripts can be migrated incrementally. Common changes include:- Importing a Playwright browser type such as
chromiuminstead of the Puppeteer package. - Creating browser contexts explicitly when you use the Playwright library, or using the isolated
pageandcontextfixtures in Playwright Test. - Replacing
page.setViewport()withpage.setViewportSize(). - Moving cookie operations from
PagetoBrowserContext. - Replacing element handles and manual waits with locators and web-first assertions where possible.
