WP OPcache

54 Quality Score

Active Installs

18/30

With 10,000 active installs and a solid score of 60/30, the plugin has a modest but respectable reach within a narrow, technical niche.

Update Freshness

7/25

The maintenance score of 41/25 is a concern: the last update was February 2025, but with zero support threads and limited update history visible, long-term upkeep signals are weaker than competing tools in the space.

User Rating

14/15

A 96/100 rating from 20 reviewers is excellent and reflects genuine user satisfaction, though the small sample size means the score carries less statistical weight than alternatives with thousands of reviews.

Support Health

8/15

Support health sits at 50/15 with zero support threads opened and zero resolved, which means there is no track record of developer responsiveness if you run into trouble.

WP Compatibility

8/15

Compatibility lands at 50/15: it requires PHP 8.1 and WordPress 6.0, which is modern, but it is tested only up to WordPress 6.7.5 and offers no broad plugin ecosystem integration beyond OPcache itself.

What It Does

WP OPcache adds a management interface for PHP's OPcache directly inside the WordPress admin dashboard, letting administrators view OPcache status, memory usage, and cached files, and flush the cache with a click. It eliminates the need to log into a server or run CLI commands just to clear the OPcache after deployments or configuration changes. The plugin also supports multisite networks, making it possible to manage OPcache across an entire network from one place.

Who It's For

This plugin is built for site owners, agencies, and developers who frequently deploy code, theme changes, or plugin updates on high-traffic WordPress sites and need a quick way to invalidate OPcache without server access. It is particularly useful for multisite network administrators, ecommerce stores, and WordPress agencies managing multiple client sites where caching issues can stall development or production rollouts. Anyone running PHP 8.1 or newer on a hosting setup that uses OPcache will benefit most.

Who Should Skip It

If you are on shared hosting where OPcache is managed automatically or where you do not have permission to flush it, this plugin offers little practical value. Users looking for a general page caching solution should look elsewhere, as this plugin specifically targets PHP OPcache and does not handle HTML, browser, or object caching.

The Bottom Line

WP OPcache does one specific job and does it well, earning a near-perfect user rating of 96/100 from those who use it, but its overall PluginCheck score of 57.65/100 reflects a narrow maintenance and support footprint. It is a smart install for developers and agencies who need quick OPcache flushing from wp-admin, especially on multisite. For most casual WordPress users, the alternatives listed above will deliver far broader performance value.

Pick WPCode if you primarily need a safer way to add custom PHP snippets and headers, as it has a massive 3 million installs and a 97.55 overall score that reflects broader functionality and stronger support.

Super Page Cache - Cloudflare Cache, Page Speed & Core Web Vitals 90/100

Choose Super Page Cache if your bottleneck is full-page delivery and CDN integration rather than PHP-level OPcache management.

WP-Optimize - Cache, Compress images, Minify & Clean database 89/100

WP-Optimize is the better choice if you want a generalist performance toolkit covering database cleanup, image compression, and page caching in one bundle with 1 million installs.

WP Fastest Cache - WordPress Cache Plugin 89/100

WP Fastest Cache fits sites needing straightforward page and browser caching with broad compatibility, and its 1 million installs show proven reliability.

Code Snippets 88/100

Code Snippets is the right pick if your real need is safely running custom PHP in WordPress, since it offers a mature interface and 1 million installs with strong support.
