In-Memory Relay Integration
Support for the Relay PHP extension. Replicates hot keys into local server memory, delivering cache reads at native memory speeds—removing network trips to Redis.
Persistent Object Cache
The Redis Caching Engine built for serious WordPress scale.
Apex Cache Pro replaces the standard WordPress object cache with an enterprise-ready Redis engine. Designed for sub-millisecond responses, multisite environments, cluster topologies, and modern in-memory acceleration.

Core Features
Engineered without compromises.
We did not copy traditional WordPress object caching plugins. We rebuilt the cache pipeline from the ground up, utilizing modern Redis capabilities.
Stampede Protection (XFetch)
Implements probabilistic early expiration. Recalculates expiring cache entries in the background before they die, preventing database bottlenecks when keys expire.
O(1) Invalidation Groups
Instead of executing heavy `KEYS` scans, Apex Cache Pro tracks cache groups with Redis sets, enabling constant-time flushing that does not hang your Redis instance.
Strict TLS & Auth ACLs
Encrypt connections in transit using TLS. Supports modern Redis Access Control Lists (ACLs) to authenticate specific roles with customized read/write permissions.
Live diagnostics panel
Fully integrates into the WordPress admin panel. Monitor connection statuses, latency metrics, commands executed, and key eviction counts in real-time.
Multisite Network Support
Isolate cache namespaces between sub-sites in multisite networks. Manage global transients easily and scale network operations safely under a single config.
