Docket Cache – Object Cache Accelerator

81 Quality Score

Active Installs

19/30

With 20,000 active installs, Docket Cache has a modest but respectable user base that is much smaller than mainstream caching plugins like LiteSpeed Cache or WP-Optimize.

Update Freshness

25/25

The plugin was updated on June 2, 2026, and is tested against WordPress 7.0, signalling that the developer is actively maintaining compatibility with upcoming releases.

User Rating

15/15

A 98 out of 100 rating from 50 reviews is excellent, though the small sample size means the score should be treated as a positive early signal rather than a proven track record.

Support Health

8/15

There are zero support threads and zero resolved tickets, which suggests either that the plugin is so simple it rarely breaks or that the developer has not opened a public support channel.

WP Compatibility

15/15

Requiring PHP 7.2.5 and WordPress 5.4 while being tested through 7.0 gives it wide compatibility across modern hosting environments.

What It Does

Docket Cache stores your WordPress site's transient and object cache data in PHP's OPcache memory, eliminating most database calls for cached values on each request. It drops in as a drop-in object cache replacement without requiring Redis, Memcached, or any external server. The practical result is faster page loads on hosts that do not offer dedicated caching services.

Who It's For

This plugin is built for WordPress site owners on shared or managed hosting where Redis or Memcached are not available, but the server still has OPcache enabled. It fits small businesses, blogs, and agencies that want a meaningful speed boost without paying for a VPS upgrade or third-party cache service. Sites running on PHP 7.2.5 or higher will benefit most.

Who Should Skip It

If your host already offers Redis or Memcached object caching, you are better off with Redis Object Cache, which delivers comparable speed with a more battle-tested architecture. Also skip this plugin if you are on a custom server setup without OPcache enabled, since the entire approach depends on it.

The Bottom Line

Docket Cache earns an 81.46 overall quality score and fills a genuine gap for sites that need object caching without Redis or Memcached. The 98/100 user rating is encouraging, but the small install base and zero support threads mean you are placing some trust in a relatively niche project. It is a sensible pick for shared hosting users who have hit the limits of page-cache-only solutions.

Related Plugins

LiteSpeed Cache 95/100

Pick LiteSpeed Cache instead if your site runs on a LiteSpeed web server, as it delivers more aggressive server-level caching plus image and CSS optimization.

Jetpack 94/100

Pick Jetpack when you need object caching bundled with backups, security scanning, and CDN in one subscription.

Redis Object Cache 92/100

Pick Redis Object Cache if your hosting environment offers Redis, since it scales better under heavy load and handles larger datasets than OPcache-based caching.

Super Page Cache 90/100

Pick Super Page Cache when your priority is full-page caching at the CDN edge rather than backend object caching.

WP-Optimize 89/100

Pick WP-Optimize if you also need database cleanup, image compression, and minification alongside caching.
