Caching
Served before WordPress even loads
Page, mobile, browser and object caching working as one. Static HTML is delivered before PHP starts — no database, no plugin chain — and rebuilt automatically when you publish.
Page & mobile cache with per-post rules
Browser cache headers for instant repeat visits

Optimization
Smaller, fewer, faster assets
Minify and combine HTML, CSS and JS, defer or delay scripts, and load CSS asynchronously — all with a safe-minify fallback that auto-skips anything that could break.

PRO · INTELLIGENCE
The AI layer that tunes itself
Pro adds a brain on top of the engine: it scores your site, finds what's slow, and fixes it. Frequently-missed URLs get warmed, conflicts get auto-resolved, and stale cache heals itself.
