Postman vs Playwright: The Side-by-Side Breakdown
Postman versus Playwright pulls in opposite directions on a few axes that matter for Testing. Postman stakes api client and collaboration platform that started as a chrome extension and now covers design, testing, and mocking on mock servers from saved request examples, newman cli for running collections in ci, public api network with vendor-published collections. Playwright counters with microsofts open-source end-to-end browser testing framework for chromium, firefox, and webkit with one api: drives chromium, firefox, and webkit with one api, auto-waiting assertions reduce flaky tests, trace viewer with full timeline of actions and network. Playwright wins on day-one cost. Playwright is open source. Fans of Postman cite public collections shortcut adoption of new apis.
