Cachelis Engine
The engine on our side. It opens your pages in a real browser, works out what a fast first screen needs and builds an optimized version of every page.
Cachelis / WordPress speed
Cachelis: a fast WordPress site without broken layouts
Cachelis is a managed WordPress speed optimization system by sauzend. Our separate engine opens every page in a real browser, builds an optimized version of it, and visitors receive ready-made static HTML without running WordPress, PHP or the database.
Before you buy, we test Cachelis on your site for free, so you see the result before you pay.
From €40 per year, depending on the size of your site. Our team handles setup, configuration and support; only a lightweight plugin is installed on your server.
What is Cachelis
A speed system that works outside your server
Cachelis is an alternative to WordPress caching and optimization plugins. The key difference: the heavy optimization work is done by our separate engine, not by the client’s server. We connect, configure and maintain the system ourselves.
Cachelis has two parts that work together.
Cachelis for WordPress
A lightweight plugin on your site. It connects the site to the engine and serves the ready-made fast pages to visitors.
The problem
Why WordPress is slow and why cache plugins do not always fix it
WordPress builds a page on every request: it runs PHP, queries the database and loads the theme and plugins. Themes and page builders add a lot of CSS and scripts that not every page needs.
Slow server response
Each page is built again, so the site waits for PHP and the database before the browser can start drawing anything.
Unused CSS and scripts
The theme and builder load styles and code for the whole site, while a given page needs only part of them.
Broken layouts after aggressive optimization
Typical optimizers often strip hover and animation styles or classes added by scripts. Menus, sliders and pop-ups break.
Load on your hosting
Optimizing and caching on the same server uses its resources, and the settings have to be tuned and tested by you.
Benefits
What Cachelis gives you
Instant server response
Anonymous visitors get ready-made static HTML without running WordPress, PHP or the database.
Optimized for three screens
Every page is rendered for mobile, tablet and desktop, so first-screen styles are accurate for each.
Layouts do not break
Hover and focus states, animations and classes added by slider, menu and pop-up scripts are preserved.
A faster first screen
Critical CSS is inlined, scripts are deferred and the main above-the-fold image (LCP) loads with priority.
Automatic updates, no manual cache
After a page is saved, visitors see current content and the optimized version is rebuilt automatically.
Less load on your hosting
The heavy work happens on our side; your server just serves finished pages.
How it works
A page’s path through Cachelis
- 01
Rendering in a real browser
The engine opens every page in a real browser at three screen sizes: mobile, tablet and desktop.
- 02
Only the CSS that is used
For each page we detect the CSS that is actually used. The rest is removed, while hover, focus, animations and script-added classes are kept.
- 03
A fast first screen
Critical CSS is inlined into the page, scripts are deferred and the main above-the-fold image loads first.
- 04
A static HTML version
The finished page is saved as static HTML.
- 05
Instant delivery
Anonymous visitors receive this version immediately, without WordPress, PHP or the database.
- 06
Dynamic where it matters
Logged-in users, the admin area, cart and checkout keep working as usual, in dynamic mode.
Automatic updates
Edit a page and visitors see the new version straight away
Cachelis tracks changes on the site by itself, so nobody has to think about the cache.
The old version is withdrawn at once
As soon as a page is saved, the previous fast version stops being served and visitors see current content. About 30 seconds later the page is optimized again automatically.
No manual cache clearing
Outdated content is never shown, so neither you nor your editors need a “clear cache” button.
Broken URLs show up quickly
Pages that return errors or 404 are recorded during scanning, which also helps you find broken links on the site.
Comparison
A typical cache plugin vs Cachelis
We compare approaches, not specific products: every tool has its own settings and use cases.
| Criterion | Typical cache plugin | Cachelis |
|---|---|---|
| Where optimization runs | On the site’s server, using its resources | On our separate engine |
| How the needed CSS is found | Rules or code analysis, often the same for every screen | Rendering in a real browser for mobile, tablet and desktop |
| Hover, animations, script-added classes | May disappear when “unused” CSS is removed | Preserved |
| Serving pages to anonymous visitors | Depends on settings and hosting | Ready-made static HTML without WordPress, PHP or the database |
| Updates after editing | Often needs a manual cache purge | Old version withdrawn at once, new one optimized automatically |
| Who configures and monitors it | The site owner or a developer | The sauzend team |
| What is installed on the server | A plugin that does all the work | Only a lightweight connector plugin |

Questions and answers
Frequently asked questions about Cachelis
What is Cachelis?
Cachelis is a managed WordPress speed optimization system by sauzend. It consists of the Cachelis Engine, which builds optimized versions of pages in a real browser, and the lightweight Cachelis for WordPress plugin, which serves those pages to visitors.
How is Cachelis different from regular caching plugins?
Typical caching and optimization plugins optimize on the site’s own server and are configured by the owner or a developer. With Cachelis, optimization is done by our separate engine: it renders every page in a real browser at three screen sizes and keeps the styles the page needs. Our team takes care of setup, configuration and support.
What hosting do I need?
You do not need a separate server: only the plugin is installed on your hosting. During the audit we check your hosting and, if fast page delivery needs web server settings, agree them with you in advance.
Is Cachelis compatible with Elementor and Gutenberg?
Yes. Cachelis is compatible with Gutenberg and Elementor. Pages are rendered in a real browser, so the builder’s styles and scripts are taken into account exactly as a visitor sees them.
Does Cachelis work with WooCommerce?
Yes. The catalog, categories and product pages are served as fast static pages, while the cart, checkout and customer account work in normal dynamic mode.
Can I use Cachelis with Cloudflare or another CDN?
Yes, Cachelis works alongside a CDN. During setup we align the CDN cache rules so visitors do not get an outdated version after pages are edited.
What happens when I edit a page?
As soon as you save the changes, the old fast version stops being served and visitors see current content. About 30 seconds later the page is optimized again automatically. There is no need to clear the cache manually.
How does Cachelis affect SEO?
Search engines receive the same content as visitors, only faster: we never serve different pages to bots. Google uses page speed and Core Web Vitals among its page experience signals, and Cachelis also records pages with errors and 404s during scanning, which helps you find broken URLs.
What is installed on my server and who can access the engine?
Only the Cachelis for WordPress plugin is installed on your server. Data exchange between the site and the engine is protected with a cryptographic signature, and only the sauzend team can manage the engine.
How much does Cachelis cost and how do I start?
Cachelis costs from €40 per year; the exact price depends on the size of your site: number of pages, theme and whether it is a store. Existing sauzend clients get a 50% discount. Send an enquiry and we will run a speed audit and confirm the price before setup. Before you buy, we can test Cachelis on your site for free.
