FAQ

Why not just use PageSpeed Insights?

PageSpeed Insights is useful for one-off checks and lab-style analysis, but it does not show how your real users experience performance day after day. Laglog continuously collects real-user metrics from your actual visitors, so you can see which pages are slow, where issues happen, and how performance changes over time.

Why not use synthetic monitoring instead?

Synthetic monitoring shows how a scripted test performs from controlled locations and devices. That is helpful for baseline checks, but it can miss what real visitors see across browsers, devices, and network conditions. Laglog focuses on real-user performance insights, so decisions are based on production traffic rather than simulated sessions.

How is Laglog different from other RUM tools?

Most RUM tools give you raw data and leave the investigation to you. Laglog does the investigation for you, turning metrics into a clear issue description, affected pages, and prioritized fixes.
