Real data · our own site

Real users, real numbers

This is siteflare.eu's own p75 Core Web Vitals — measured by the very beacon we'd put on your site. We monitor ourselves, live.

Core Web Vitals — p75, the way real visitors experience siteflare.eu

Loading real-user metrics…

How it works

One line of code. Then the truth.

  1. 1

    Add one line

    Paste a single script tag into your site — or we install it for you.

  2. 2

    We measure real visitors

    Every page load reports Core Web Vitals — cookieless, async, invisible to your users.

  3. 3

    See it & act on it

    p75 vitals by device and page, a monthly report, and a fix list the moment something regresses.

Install

<script>window.SITEFLARE_RUM = { site: 'yoursite.com' };</script>
<script src="https://rum.siteflare.eu/rum.js" async></script>

Under 2 KB · cookieless · no consent banner needed.

Why real-user data

Lab tests are a lab. Your customers aren't.

Real devices & networks

Measured on your visitors' actual phones, laptops and connections — not a fast lab machine.

Cookieless & GDPR-friendly

No cookies, no personal data, no consent banner — just performance numbers. Self-hosted in the EU.

p75, the way Google ranks

We report 75th-percentile Core Web Vitals — the exact figure Google uses as a ranking signal.

Tiny & async

Under 2 KB, loaded async with sendBeacon — the script never slows the page it measures.

Questions

Real-User Monitoring FAQ

Does it slow my site down?

No — the beacon is under 2 KB, loads async, and uses sendBeacon, so it never blocks the page.

Do I need a cookie banner?

No. It collects performance numbers only — no cookies, no personal data, nothing that needs consent.

What is p75?

The 75th-percentile experience — what 3 in 4 of your visitors get, or better. It is the exact metric Google uses for Core Web Vitals.

How is this different from Lighthouse?

Lighthouse is one lab test on a fast machine. RUM is your real visitors, on real devices and networks, measured continuously.
