Range Redis

Blistering fast Redis object cache for WordPress. Activate it, point it at Redis (or let it find Redis for you) and every option, post, term, user and plugin lookup stops hitting the database.

• Works with Redis, Valkey, KeyDB, Dragonfly, and managed services such as AWS ElastiCache, Upstash, Redis Cloud and DigitalOcean.
• phpredis or the bundled Predis client — TCP, TLS and Unix sockets.
• A real settings screen: auto-detect, connection test, save. No wp-config.php editing required (but fully supported).
• Imports existing Redis Object Cache / Object Cache Pro settings.
• Resilient: circuit breaker, automatic integrity flush after an outage, graceful degradation to memory-only.
• Observable: dashboard widget, Site Health checks, Query Monitor and Debug Bar panels, WP-CLI, REST API.
• Self-describing values: change serializer (php / igbinary) or compression (gzip) at any time without flushing.

Install

1. Download the latest release zip from the Releases page, or composer require rangefrontlabs/range-redis.
2. Activate the plugin. If Redis runs on the same server the cache is enabled immediately; otherwise open Settings → Range Redis → Connection.

Requires PHP 8.0+ and WordPress 6.0+.

Configure (optional)

// wp-config.php
define( 'RANGE_REDIS_CONFIG', array(
    'host'       => '127.0.0.1',
    'port'       => 6379,
    'database'   => 1,
    'serializer' => 'igbinary',
    'compression' => 'gzip',
) );

Every option is documented at https://rangefrontlabs.github.io/range-redis-site/docs/configuration.html.
