Playwright and Postman are often evaluated together by teams building out their reliability stack. Playwright (open-source browser automation and end-to-end testing, founded 2020) is typically a fit for Developers, SDETs, and QA Engineers, while Postman (api platform for building, testing, and monitoring apis, founded 2014) leans toward Developers, QA Engineers, and API Teams. Both cover 4 of the same core capabilities, so the decision usually comes down to where they diverge.
