Playwright Grid on GitHub Actions
Every team that gets serious about end-to-end testing eventually builds the same thing: a pipeline that takes a pull request, spins up browsers somewhere, runs the suite, and reports back. In 2026 the default stack for this is Playwright on GitHub Actions - no Selenium Grid hub/node topology to babysit, because Playwright's own worker model plus CI-level sharding is the grid.
