kubermatic.com website review

5 images could be 298 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 550 ms faster on a phone.

1 file blocks the first paint until they finish downloading. Deferring or inlining it could save about 750 ms.

Polyfills for old browsers add 11 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 150 ms faster on a phone.

Critical files load one after another instead of in parallel (3 chains). Preconnecting to key origins and preloading the hero image shortens the chain.

Scripts make the browser recalculate the layout repeatedly while the page loads, which wastes processor time on phones.

Real Chrome users on phones do not pass Google's Core Web Vitals on this page (28-day field data from the Chrome UX Report (opens in a new tab)). Google uses this in ranking.

Over the last 25 four-week periods to 2026-10-17, real Chrome visitors' largest content (lcp) went from 1.6 s to 2.4 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Real visitors see the first content after 2.1 s (75th percentile). Good is under 1.8 s.

Real visitors wait 1.3 s for your server to start answering (75th percentile). Good is under 800 ms.

Visually, the page fills in at 4.3 s (Speed Index). Good is under 3.4 s.

Your largest element takes 2.8 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “Scale Your Business on the AI Cloud-Native Platform”. Most of its time is element render delay (2.4 s).

Over the last 25 four-week periods to 2026-10-17, real Chrome visitors' tap response (inp) went from 125 ms to 130 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

3 images (330 KiB) are JPEG, PNG or GIF. The same pictures as WebP or AVIF are usually much smaller at the same quality, and every current browser shows them.

By the Sustainable Web Design model, a visit to your homepage emits about 0.53 g of CO₂e: 63.3 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

13 text elements don't have enough contrast against the background to read easily, especially outdoors on a phone.

Interactive controls must not be nested: 1 element on the page fails this check, rated serious by axe-core.

All page content should be contained by landmarks: 1 element on the page fails this check, rated moderate by axe-core.

1 error was logged to the browser console while the page loaded, for example “Failed to load resource: net::ERR_FAILED”.

1 image is served at too low a resolution for sharp phone screens.

Your homepage shows a street address but no LocalBusiness JSON-LD, so Google and AI assistants have to guess your address, hours and phone from the page text.

A local customer looking to call finds no phone number on the homepage. Add one, ideally as a tap-to-call link.

No phone number or email link on the homepage, so ready-to-buy visitors have one fewer way to reach you.

The homepage shows no opening hours. If customers visit or call, show when.

There is no form on the homepage, so every lead has to click through to another page first.

There is no link to Google or Apple Maps. A directions link is one tap for a phone visitor.

No guarantee or risk reducer (money-back, free trial, no credit card) is mentioned, which is often what tips a hesitant visitor.

The homepage carries about 997 words of visible text.

No known cookie consent tool loads with the page. Some sites build their own banner, and some only show one to visitors from the EU.
