About PerfHawk
A focused web-performance monitor that watches your Core Web Vitals, lab and field, mobile and desktop, so you stay fast.
Our mission
Performance is a feature, but it quietly erodes between releases. Our mission is to make that drift visible: track the metrics Google ranks on, in plain numbers you can act on, and tell you the moment a page slows down, before your users feel it.
What we do
PerfHawk pulls real performance data from Google's own sources and turns it into a clear, daily picture of how your pages load:
- Lighthouse lab scores for mobile and desktop, side by side
- Real-user Core Web Vitals (LCP, INP, CLS) from the Chrome UX Report
- Daily checks with a readable history of every metric over time
- Email alerts the moment a page regresses
Who we are
PerfHawk is built by Click&Mortar, a digital agency based in Paris, France. We spend our days shipping and tuning web applications, so we built the performance panel we wanted to live in: precise, calm, and honest about the numbers.
How we work
Clarity over noise
State the number, then what to do about it. One accent colour, real type, no dashboard theatre. If everything is highlighted, nothing reads as a signal.
Field over guesswork
We lead with how real Chrome users actually experience your pages, then back it with lab diagnostics, not synthetic scores in isolation.
Privacy by default
EU hosting, cookieless analytics, and strictly necessary cookies only. We collect what the service needs and nothing more.
Genuinely helpful
Built by people who live in the performance panel. Ask us anything. We answer like engineers, not a ticket queue.
Our infrastructure
PerfHawk runs on Hetzner's infrastructure in Germany, keeping your data within the European Union. Performance results come from Google's PageSpeed Insights and Chrome UX Report APIs. There is no crawler touching your site.
