Keep your existing site exactly as it is. CentumSpeed diagnoses it with AI, rewrites it at the edge, and serves the fast version to every visitor. Green Core Web Vitals — without touching your code.
60-second scan · no signup · no credit card
Fewer than half of all websites pass Google's Core Web Vitals on mobile. Google notices. So do your visitors.
No plugin to install, no theme to change, no developer to hire. If you can copy-paste one DNS record, you can do this.
Enter your address. Our AI runs Google's own PageSpeed audit, reads the results, and tells you in plain words exactly what is slowing your site down — and how many points each fix is worth.
Point one DNS record at CentumSpeed. That's the whole installation. Your site, hosting, and CMS stay exactly where they are — we sit in front, like a shield.
Every page is rewritten and served from the edge: fonts self-hosted, images converted, scripts deferred, HTML cached worldwide. Watch the score climb into the green.
Our AI reads your audit and applies only what your site needs. Every optimization runs on our edge — your original site is never modified.
Google Fonts, libraries and widgets get served from your own domain via our edge — no external lookups blocking your render.
Every image auto-converted to AVIF/WebP, resized to its real display size, and lazy-loaded below the fold.
Chat widgets, trackers and analytics wait until the visitor actually interacts. Total Blocking Time drops to near zero.
We render your pages, extract the CSS needed above the fold, inline it, and defer the rest. First paint gets dramatically faster.
Whole pages cached in 300+ cities worldwide. Time-to-first-byte falls from seconds to ~50 milliseconds.
No 40-toggle settings panel. One report that says what was wrong, what we did, and what it's worth — in words, not jargon.
Nothing about your website changes for you — everything changes for Google and your visitors.
Flat price per site. We never count your pageviews, and we never hold your speed hostage to an upgrade button.

No. Your site, CMS, and hosting stay untouched. You point one DNS record at CentumSpeed and we serve an optimized copy of every page. Remove the record and everything is instantly back to how it was.
Most do. We guarantee 90+ on every plan. Sites carrying heavy third-party ads may land in the high 90s — we'll tell you honestly in the free scan, before you pay anything.
All of them. WordPress, Shopify, Wix, Squarespace, Webflow, custom code — because we work at the DNS level, the platform underneath doesn't matter.
The AI tests every optimization against your real pages before enabling it, and anything can be switched off per page. Your original site is never modified, so there's nothing to restore.
The scan is free, takes a minute, and tells you exactly how many points you're leaving on the table — whether you sign up or not.
