Speed of Light is an all-in-one WordPress performance plugin. It combines three layers of caching — a static disk page cache, a built-in Redis object cache, and full-page caching at Cloudflare's edge (on the free plan) — with automatic CSS, JavaScript, image, and font optimization. A real-browser cloud engine works out exactly what each page needs, and Autopilot applies the safe fixes for you. The result: green Core Web Vitals without a developer, a stack of plugins, or a monthly CDN bill.

Most WordPress sites are slow because the page is rebuilt from scratch on

every visit — PHP runs, the database is queried, then a big pile of CSS

and JavaScript is shipped to the browser.

Speed of Light removes that work at every layer:

• PAGE CACHE — serves a ready-made HTML copy of each page straight from

disk, before WordPress or PHP even boot.

• OBJECT CACHE (built in) — a native Redis object cache stores the

repeated database queries WordPress makes, so uncached pages build far

faster. This is our own engine — no separate "Pro" add-on to buy.

• EDGE CACHE — connects to Cloudflare using the modern Cache Rules API to

serve full pages from Cloudflare's global edge, answering visitors close

to them. It works on Cloudflare's FREE plan — no monthly CDN bill.

• ASSET OPTIMIZATION — minifies and combines CSS/JS, removes unused CSS,

inlines critical CSS, delays non-critical JavaScript, lazy-loads images,

serves next-gen WebP/AVIF, and self-hosts Google Fonts.

• CORE WEB VITALS — measures LCP, INP and CLS from real visitors (75th

percentile field data, like Google CrUX) and fixes what's dragging them

down.

One plugin does the job of a page-cache plugin, an object-cache add-on, a

CDN subscription, an image optimizer, and a "remove unused CSS" tool.

HOW IT WORKS (the mechanism, step by step)

1. INSTALL & IT CONFIGURES ITSELF.

On activation, Speed of Light profiles your site and server (PHP

version, object-cache backend, theme, host capabilities) and turns on

the safe optimizations automatically. There are no "modes" to pick — it

tunes itself.

2. PAGES ARE SERVED FROM CACHE.

Once a page is cached, it's served as static HTML from disk — skipping

PHP and the database entirely — and, when Cloudflare is connected, from

the edge. A background preloader warms every page so visitors always

hit a ready copy.

3. A REAL BROWSER DECIDES WHAT EACH PAGE NEEDS.

For licensed sites, each page is rendered once in a real cloud Proprietary Chromium

browser. That render reports exactly which CSS the page actually uses,

the true Largest Contentful Paint element to preload, the correct image

dimensions, layout-shift (CLS) fixes, and which scripts are safe to

delay. Speed of Light then applies all of it and serves the optimized

page from your own server. If the cloud is ever unavailable, it falls

back to on-server optimization — so your site can never break.

4. AUTOPILOT KEEPS IT FAST.

The Performance Detective diagnoses issues in plain English and applies

the safe fixes for you, snapshotting your previous settings first. Every

change is visible, and anything can be undone in one click. Excluded

pages (cart, checkout, account) are left completely untouched.

Zero-config: background tasks run on normal site traffic, so preloading and

purging work even without WP-Cron or a server cron job. Install, activate,

walk away.
