I built a Playwright monitor after CI passed but the live UI was broken, would this be useful? AI-assisted development has made it much easier for me to ship changes quickly. The downside: I’ve seen CI pass while the live page still had issues that customers would notice first broken-images, console errors, layout shifts, and overflowing text. The lesson for me was that tests and logs are necessary, but they don’t always show what a real visitor sees after deployment. So I built Lampwatch
