Redis Object Cache
500,000+ active installs · Rated 4.5/5 · Updated September 18, 2026
A persistent object cache backend that stores WordPress object cache data in a Redis server. It supports the Predis, PhpRedis, Relay and Credis clients, plus Sentinel and replication setups. It suits sites with a Redis server and sites that want a cache drop-in managed from the admin. It only caches objects, so it does not replace a page cache, and the free version shows upgrade prompts for the paid Object Cache Pro.
Pros
- Supports several Redis clients, including Relay and PhpRedis
- Sentinel and replication configuration in the free version
- Status, diagnostics, WP-CLI commands and a flush action in admin
Cons
- Object cache only: no page caching, minification or CDN
- Needs a reachable Redis server and PHP client extension or library
- Shows upgrade prompts for the paid Object Cache Pro
