Monitoring as Code: E2E Testing in Production with Playwright
summary
Playwright scripts become production monitors: browser and API checks run every 15 minutes from multiple regions (demo ran from Ireland and Frankfurt and executed in US East), produce time‑travel traces and video, and use storageState to capture reusable authentication so hundreds of checks avoid re-login. A CLI deploys Playwright checks to a cloud runtime (Checkly), runs them in parallel (scale needs bigger machines), shows failures in traces, and already serves 1000+ customers in production.
