Everything you need to be fast.
Caching, edge delivery, a native object cache, asset optimization and real-user monitoring — one engine that configures itself, in every plan.
Twelve engines. One install.
Built for the modern, block-based, edge-delivered web — and all included in every plan.
Edge-aware page cache
Gzip/Brotli-ready HTML served from disk via an advanced-cache.php drop-in — before WordPress boots. Atomic writes never corrupt.
Smart Configuration New
Analyzes your theme, builder, host and plugins, then recommends and safely applies the optimal settings.
Premium Redis object cache New
A drop-in persistent object cache with value compression, live diagnostics and a real GUI — the kind others sell as a separate plugin.
One-click Cloudflare edge
Full-page caching on the free plan via Cache Rules + 103 Early Hints — no monthly CDN bill, no Page Rules used.
Accurate Critical CSS
Pixel-accurate Critical CSS and Remove Unused CSS, generated automatically — no manual selectors.
Delay & defer JavaScript
Load non-critical scripts on interaction — with ads, analytics and payment scripts protected by default.
Intelligent preloader
Warms every URL after each purge, learns your server's throughput, and can bypass your CDN/WAF during preload.
Smart image delivery
WebP/AVIF conversion, lazy-loading that skips your hero, and fetchpriority on the real LCP image.
Real-User Monitoring
LCP, INP, CLS, FCP & TTFB from real visitors — stored on your own site, never shared with anyone.
Database health
Size, autoload and fragmentation insight, plus safe cleanup of transients, trash, revisions and orphaned meta.
Kill Bloat
Disable emojis, embeds, XML-RPC, dashicons and more. WooCommerce-aware — drop cart fragments off non-shop pages.
Self-hosted fonts
Pulls Google Fonts local, preloads them and adds font-display: swap — no third-party round-trip, no invisible text.
A premium object cache, included.
Most sites pay extra for a serious Redis object cache. Speed of Light ships one in the box — a real drop-in that takes the repeated work off your database on every request, with its own dashboard.
- Value compression — zstd / lz4 / gzip, with live savings.
- Fast igbinary serialization — compact values, quick reads.
- Live diagnostics GUI — hit ratio, memory, evictions and ops.
- Stays up if Redis blips — graceful in-memory fallback.
It configures itself.
Smart Configuration reads your environment and turns on exactly what your site needs — warning you before anything risky.
- Auto-applied — safe optimizations switch on for your stack, automatically.
- Override guard — your manual changes are never silently undone.
- Full manual control — every setting, plus WP-CLI and a REST API.
Scriptable, hookable, yours.
Automate everything from CI or the command line — and customize the engine with hooks and constants.
- WP-CLI for cache, preload, RUCSS & object cache.
- REST API with 20+ endpoints.
- 30+ hooks & constants for full control.
Built for the stack you run.
Auto-detects 10+ themes and 5+ builders, ships safelists, and warns about 15+ conflicting cache plugins.
Block themes & Blocksy
Designed around the block editor — not a legacy engine retrofitted for it.
GreenShift & builders
Safelisted so unused-CSS removal and script delay never strip what your builder needs.
WooCommerce-safe
Carts, checkout and sessions are never cached — recognizing 20+ known cookies.
The whole stack, one price.
Install, enter your key — and let every visitor land on a page that's already waiting.
