Introduction

MilliCache Pro is the premium extension of MilliCache, the most flexible full-page cache for scaling WordPress sites. It builds on everything MilliCache does (in-memory page caching, flag-based invalidation, the rules engine) and adds the tooling and infrastructure features that production sites grow into.

What Pro Adds#Copied!

Pro is organized into modules you enable individually:

See and Control Your Cache#Copied!

  • Cache Entries Browser: every cached page in a searchable table, with flags, variants, size, and expiry, and per-entry deletion.
  • Visual Rules Builder: build caching rules in the UI instead of PHP. Match by URL, cookie, query, or WordPress conditionals; set TTLs; bypass; override built-in rules.
  • Detailed Metrics: requests, bandwidth, response times, and visitor time saved, charted on the Status dashboard with hourly and daily history.

Keep It Fast Automatically#Copied!

  • Cache Preloading: pages are rewarmed after publishing and refilled from your XML sitemap after a full clear, so visitors never wait for a page to be built.
  • Block Editor Intelligence: editing a synced pattern, a Query Loop source, or a Site Editor template clears exactly the affected pages instead of going stale or flushing everything.

Scale Beyond One Server#Copied!

  • Edge Cache: serve cached pages from bunny.net or Cloudflare edge locations, tagged and purged together with the local cache.
  • Asset CDN: serve static files from a pull zone, with rewritten URLs baked into the page cache at zero runtime cost.
  • Object Cache: a persistent WordPress object cache drop-in on the same storage connection, speeding up wp-admin and uncached pages.
  • Storage Connections: configure Redis replication and Sentinel from the UI.

Everything ships with matching WP-CLI commands.

How Pro Relates to MilliCache#Copied!

MilliCache Pro includes the MilliCache engine: MilliCache Pro is the only plugin you install, giving you the full page cache plus the Pro modules. If the MilliCache plugin is active when you activate Pro, it is deactivated automatically and the bundled engine takes over with your settings and rules intact; see upgrading from MilliCache.

Without an active license, everything MilliCache itself provides keeps working; the Pro modules stay locked until you activate a license.

Requirements#Copied!

Component Requirement
PHP 7.4 or higher
WordPress 6.6 or higher
