The difference with other CDNs

Why QUIC.cloud is unique

The only CDN for dynamic WordPress content

QUIC.cloud is the only CDN in the world that can cache both static and dynamic WordPress content. While traditional CDNs can only cache images, CSS and JavaScript, QUIC.cloud also caches your complete WordPress pages, including dynamic content such as WooCommerce product listings and personalized content.

This means your visitors not only load your images quickly, but your complete website is blazing fast from every continent in the world.

79 servers spread across the entire world

With 79 Points of Presence (PoPs) worldwide, your website is always close to your visitors. Whether they are in Amsterdam, New York, Tokyo or Sydney - QUIC.cloud ensures extremely low latency with an average of under 10ms in North America and Europe.

More than 5 million domains already rely on QUIC.cloud's infrastructure for their speed and reliability.

Proven results

Up to 600% speed gain

600% faster with LiteSpeed and QUIC.cloud

WordPress websites can become up to 600% faster with the combination of LiteSpeed Cache and QUIC.cloud CDN, without needing extra server resources. This is not a theoretical claim - users all over the world report these dramatic speed improvements.

The speed gain comes from the fact that QUIC.cloud not only caches your static files (like other CDNs), but also distributes your complete dynamic WordPress pages worldwide from 79 edge servers.

PageSpeed scores of 92+ without effort

Users report impressive Google PageSpeed improvements - from scores around 39 to 92 and higher, without special hosting or expensive optimization services. The free LiteSpeed Cache plugin combined with QUIC.cloud CDN does the work automatically.

Better PageSpeed scores mean not only a faster website for your visitors, but also higher Google rankings because speed is an important ranking factor.

Drastically better Core Web Vitals

QUIC.cloud specifically improves your Core Web Vitals scores - the metrics Google looks at most when ranking websites. Your LCP (Largest Contentful Paint) and FCP (First Contentful Paint) are drastically improved through image optimization and edge caching.

By loading content from the nearest CDN server and optimizing images to WebP/AVIF formats, your visitors experience an instantly loading website regardless of their location.

Everything you need

Powerful features included

Image optimization - up to 90% smaller

QUIC.cloud automatically compresses your images up to 90% smaller without visible quality loss. The system automatically converts images to modern WebP and AVIF formats for browsers that support them.

This is significantly cheaper than competitors such as ShortPixel, and more powerful than free alternatives such as SMUSH or EWWW Image Optimizer. All images are processed in the background without slowing down your website.

DDoS protection and WordPress security

QUIC.cloud offers Layer 7 DDoS protection at CDN level, brute-force protection for WordPress login forms and XML-RPC endpoints, and a Web Application Firewall (WAF) with WordPress-specific rules.

You can set up custom IP block lists, integrate reCAPTCHA at CDN level, and even block entire countries if needed for your security strategy.

Critical CSS and unused CSS removal

QUIC.cloud automatically generates Critical CSS (CCSS) that is added inline for above-the-fold content. This ensures your page is instantly renderable, even before all CSS has loaded.

In addition, Unique CSS (UCSS) automatically removes all unused CSS definitions per page, making your CSS files dramatically smaller and your website load even faster.

Smart lazy loading with LQIP

QUIC.cloud uses Low Quality Image Placeholders (LQIP) for a much better user experience than standard lazy loading. Instead of empty spaces or spinners, visitors see a blurry preview of the image that loads instantly.

Combined with Viewport Images (VPI) that exclude above-the-fold images from lazy loading, this ensures an optimal balance between speed and user experience.

The latest technology

HTTP/3 and QUIC protocol

End-to-end HTTP/3 support

QUIC.cloud supports HTTP/3 with the QUIC transport protocol end-to-end. This is the newest and fastest internet protocol, developed by Google and now an official standard.

HTTP/3 is significantly faster than HTTP/2 and HTTP/1.1, especially on mobile networks and over longer distances. It uses UDP instead of TCP, which ensures faster connections and better performance during packet loss.

HTTP/3 benefits

Faster connections: 0-RTT connection setup
Better mobility: Maintain connection when switching networks
No head-of-line blocking: Streams do not block each other
Packet loss tolerance: Better performance on poor connections
Built-in encryption: Always secure with TLS 1.3
Future-proof: The standard for modern websites

Perfect for web shops

WooCommerce caching with ESI

Cache your entire WooCommerce shop

QUIC.cloud is one of the few CDNs that can cache complete WooCommerce sites, including dynamic elements such as shopping carts, personalized prices and stock information.

This is made possible by Edge Side Includes (ESI) technology and smart cache tags. Product pages are cached on the CDN, but personalized elements remain dynamic and up-to-date.

The result: a blazing fast shopping experience for your customers, even during sale periods with high traffic, without needing expensive dedicated servers.
