GTMetrix used to be the go-to tool for checking website speed, but let’s be honest—paying for one-off synthetic tests isn’t worth it. If you’re still relying on synthetic testing alone, you’re missing a big part of the web performance picture. If you care about Core Web Vitals, SEO performance, and user experience, you need more than just lab data. The good news? There are better (and free) alternatives like PageSpeed Insights and WebPageTest for synthetic testing.

Modern applications are becoming increasingly complex, and debugging distributed systems can feel like searching for a needle in a haystack. This is where OpenTelemetry (OTel) comes in.
