Overview

WordPress runs many database queries on each page load, and the same data is often requested again and again. Object Cache Pro keeps that data in Redis so it can be fetched quickly. It follows the WordPress Object Cache API, which lets it work with WordPress core and with plugins such as WooCommerce, Jetpack and Yoast SEO. It reduces unneeded Redis reads and writes to keep memory use low.

The plugin also gives you tools to see what the cache is doing. Site Health widgets, WP CLI commands, Query Monitor and Debug Bar panels show cache status and metrics. It supports multisite networks and can run as a must-use plugin. A small blog can use it, and so can a busy WooCommerce store or a membership site that needs a steady caching layer.

Features

Redis object cache backend: Object Cache Pro is built for WordPress and stores data in Redis, which cuts redundant database queries and speeds up cache retrievals.
WordPress Object Cache API compliance: It follows the WordPress Object Cache API, so it fits with core and with plugins like WooCommerce, Jetpack and Yoast SEO.
Prefetching and batch requests: Redis commands are combined into batches and data is prefetched, which eases the load on Redis servers during busy periods.
Compression options: LZF, LZ4 and Zstandard compression save Redis memory and reduce network I/O when data is retrieved.
Asynchronous flushing and cache priming: Flushing runs asynchronously and the cache can be warmed up ahead of time, which helps prevent database overload when traffic peaks.
Debugging and logging: Opt-in error reporting works with PSR-3 loggers, which makes it easier to find the cause of caching problems.
TLS connections and health checks: Encrypted TLS communication protects the connection to Redis, and health insights are available in the WordPress dashboard and through WP CLI.
Multisite and must-use support: The plugin works on WordPress multisite networks and can be deployed as a must-use plugin so it is always loaded.

Best for

WooCommerce stores with dynamic, database-heavy pages
Membership sites and high-traffic WordPress projects
Developers and hosts running Redis with WordPress
