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.
What we built on top
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.
Hardened by default
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.
The number that matters
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.
