not at the speed of PHP
Static HTML served directly from disk before WordPress loads. Zero PHP execution, zero database queries on every cache hit.
Apex intercepts every anonymous request before PHP loads. The decision takes 19 microseconds.
Web server finds the cached file on disk and sends it to the browser. PHP never starts. WordPress never loads.
Ultra-lightweight drop-in evaluates bypass conditions and generates the cache key. Zero DB queries, zero WP load.
WordPress renders once. Response reaches the browser. Cache is written asynchronously — user never waits for disk I/O.
At activation, Apex detects your environment and selects the fastest available serving method automatically.
Direct static file serving via try_files. PHP is never invoked on cache hits.
RewriteRule to static files. Auto-configured on activation via .htaccess.
Detected automatically. X-LiteSpeed-Cache-Control coordination built in.
Works on any shared hosting. advanced-cache.php serves before WordPress loads.
BASIC is a complete, production-ready cache engine. No upsell gates, no crippled features.
Edit post 42 — only pages containing post 42 are purged. Not the entire cache. SQLite tag index maps every cache entry to its WordPress content.
Purged pages are immediately re-queued at priority 1. The next visitor gets a HIT, not a MISS. No cold cache after invalidation.
HTML compressed at write time, not per-request. Both Brotli and Gzip variants stored. Zero CPU overhead on delivery.
flock(LOCK_EX|LOCK_NB) prevents thundering herd. If 100 requests arrive simultaneously for a cold URL, only one writes to cache.
Browser prefetches the next page before the user clicks. Navigation feels instant. No other cache plugin implements this.
Clients with a valid cached copy receive a 304 Not Modified response. Bandwidth savings on returning visitors, zero content transfer.
Priority queue warms the cache proactively. Homepage first, then high-traffic pages, then sitemap. CPU-aware throttling pauses on high load.
Host header validation, path traversal prevention, SSRF protection on sitemap URLs, symlink guard on cache reads, signed log directory.
Six tabs — Dashboard, Environment, Purge, Preload, Settings, Logs. Full ARIA compliance, keyboard navigation, zero external JS dependencies.
Every cache operation available from the terminal. Automate, script, deploy.
BASIC has no artificial limitations. PRO adds Redis, CDN, and enterprise features.
Complete static cache engine. No limitations. No expiry. No credit card.
Redis acceleration, CDN orchestration, and enterprise-grade performance.
