Under the hood
Fast because of
how it's built.
DPX is built on Pingora — the Rust framework Cloudflare wrote to replace nginx, and now uses to serve much of the web. But Pingora is a framework, not an accelerator: the two-tier cache, the image and CSS work, the Plesk integration and the firewall are ours. That's the part that makes a page fast.
The foundation
The engine: Pingora.
Cloudflare open-sourced Pingora in 2024 under the permissive Apache-2.0 licence. At Cloudflare it handles tens of millions of requests per second, and Cloudflare reports it uses about 70% less CPU and 67% less memory than the old service it replaced, at the same traffic load. DPX is — as far as we know — the only commercial web accelerator built on it. We inherit the foundation; we add the optimization.
Those scale and efficiency figures are Cloudflare's, for Cloudflare's traffic — they're why the foundation is trustworthy, not a claim about DPX's own volume.
Purpose-built, not bolted together.
Streams by default
Anything DPX doesn't need to touch streams straight through the moment it arrives, the way a proxy should. Pages being optimized are held just long enough to rewrite correctly, then released — same request, no pre-build, nothing written to disk first.
Built-in minification
CSS and JavaScript are shrunk down automatically, in Rust, inside DPX itself — no Node build step and no separate minification toolchain to keep updated.
Local critical-CSS & images
On Hosting and Engine, critical CSS is worked out and extracted on the server itself. Images convert to WebP and AVIF as they're served, everywhere DPX runs — with no separate service in the path and nothing metered per image.
Two-tier cache
The fastest results are kept in memory, with a bigger cache on disk behind it, so popular pages stay fast. Clear the whole site's cache, or just one page, whenever you need to.
Security isn't an add-on.
Encrypted connections only, kept current automatically; a built-in firewall and opt-in per-domain security headers; rate limiting; an admin panel with modern password hashing (Argon2id) and constant-time comparisons. Written in Rust, so whole classes of memory-safety bugs are gone.
100/100. Mobile and desktop.
DPX-hosted sites score 100/100 on Google PageSpeed — including heavy WooCommerce and Elementor Pro builds. The work happens in the server, not in a stack of plugins you have to choose and tune yourself.
