Cache preheater - early access

The preheater that makes your sites actually fast.

Your cache plugins say "all good" - but the first visit still crawls for 3 seconds. Warmnep actually preheats every page and proves the gain: time before, time after, hard numbers.

The real problem

Your "preload" preheats nothing.

Plugins generate a cache... but never check that your real pages are fast. Neither do you.

!

The first visitor pays the price

Until a page has been requested, no cache serves it. The first visitor triggers a full render - 3 seconds of waiting, Lighthouse score tanking.

?

Zero hard proof

When a plugin says "preload complete", it shows you no timing. Fast or slow for a real visitor? You don't know. You hope.

The cache goes cold

Expiry, purge after an update: the cache goes cold on its own. Without regular re-preheating, your pages slow down without warning.

The Warmnep difference

A cache plugin works from the inside. Warmnep works from the outside.

That's the whole difference, and it changes the result for your visitors.

FROM THE INSIDE

The cache plugin

It builds the cache on your server, then it stops. It can't see the CDN sitting in front of your site, and it never checks what a real visitor experiences. It assumes it worked.

FROM THE OUTSIDE

Warmnep

Warmnep visits every page like a real visitor, with a real request. It warms every cache layer along the way, your server and the CDN alike. And because it lives the real experience, it measures it: time before, time after, proven gain.

Your plugin fills the cache. Warmnep makes sure it's warm where your visitors actually land, and proves it.

The solution

Real preheating, measured.

Warmnep visits every page like a real browser: it warms the cache, then measures again to prove the gain.

A

Automatic discovery

We find your sitemap (Yoast, Rank Math, static...) and list every URL - nothing to install.

B

Two-pass preheating

Pass 1: we load the cold page and warm the cache. Pass 2: we reload it - now served at full speed.

C

Before / after proof

For every page: cold time, warm time, speed multiplier. Plus a diagnosis of the pages still too slow.

Three steps

From slow to fast, with proof in numbers.

You paste your domain

No install. WordPress, Shopify, PrestaShop, Webflow, static - anything with a sitemap.

We preheat page by page

Each URL is loaded twice: cold to warm it, warm to measure the real gain. You watch the times drop live.

We prove the gain

Average time before / after and speed multiplier. With an account, you schedule it all automatically.

FAQ

The fair questions.

How is this different from a cache plugin's "preload"?

Plugin preload triggers cache generation... but never proves the page is fast. Warmnep makes real browser requests, warms the cache (server-side or CDN edge, whatever the layer) and measures the time again to show you the real gain, page by page.

How long does the speed gain last?

It depends on your cache and your updates. On every purge (new post, page edit), the affected pages go cold again. That's why paid plans re-preheat automatically: your sites stay fast without you thinking about it.

Does it work on Shopify, PrestaShop, not just WordPress?

Yes. Warmnep works on any site that exposes a sitemap - WordPress, Shopify, PrestaShop, Webflow, static sites, headless. The logic is the same everywhere: we warm, we measure, we prove.

What if a page stays slow after preheating?

Warmnep tells you, page by page. If a URL doesn't speed up, it means nothing is caching it (no plugin, no CDN) or your server is overloaded. We point you to the pages concerned so you fix the right thing.

Is it safe for my client sites?

Yes, 100%. Warmnep installs nowhere: no plugin, no access to your server, your admin or your database. We only make external requests to the public URLs in your sitemap - exactly like a visitor. Nothing can break. We respect robots.txt and store no page content, only load times.

Who's behind Warmnep?

Warmnep is built by Aloha Pixel, a web agency specialized in WordPress and performance, based in Pau and Paris. It's the tool we use every day to keep our client sites fast, and that we're now opening to everyone.
