About Metrical
Performance data shouldn't require a PhD to understand.
The problem
You've noticed your website feeling slow. Maybe pages take too long to load, or interactions feel sluggish. So you open Google PageSpeed Insights or Lighthouse and you're hit with a wall of numbers, grades, and jargon. "Eliminate render-blocking resources." "Reduce unused JavaScript." Great... but what does that actually mean for your specific site, and where do you even start?
Most performance tools are built for performance engineers. They surface every possible metric and leave the prioritisation entirely up to you. For everyone else, developers shipping features, agency teams managing client sites, founders running their own product... that's not particularly useful. We can do better.
What Metrical does differently
Metrical runs your URL through its own performance lab with real network throttling, multi-pass testing, and filmstrip capture then translates the results into plain English. Not a list of everything that could theoretically be improved, but a prioritised action plan: what to fix first, why it matters, and roughly how to approach it.
Plain English explanations
Every finding is explained in language that doesn't require you to already be a performance expert.
Prioritised recommendations
Focus on the changes that will have the biggest impact on your scores and real user experience, not a generic list of everything that could theoretically be improved.
Built-in performance lab
Metrical runs tests in its own performance lab with real network throttling. Not synthetic estimates on your local machine. Results are consistent and comparable.
Core Web Vitals focus
Google's Core Web Vitals directly influence search rankings. Metrical makes improving LCP, CLS, INP, and TTFB accessible without a specialist on your team.
Built by a developer, for developers
Metrical is an indie product. We're not a venture-backed startup with a growth team. It was built because the existing tools felt unnecessarily complex for most use cases. The goal is to stay small, focused, and genuinely useful.
