WP Super Cache

How well this listing is tuned to rank in WordPress.org search, on the factors an owner controls. Not popularity, optimization.

Directory rank vs rivals

wp.org popularity rank over time · higher is better · when a rival's line climbs above yours, they've overtaken you

How often this plugin actually ships. A steady rhythm is the maintenance signal a single "last updated" date can't show.

Share of active installs on each version of this plugin · 47% run the current release. Green is the current release; a big slice on older versions is a user base that has stopped updating.

Refined from the date this plugin crossed into its current band.

No paid tier is visible, so we don't put a figure on revenue or sale value: that would be guessing. The install base is a real asset to an acquirer, just not one public data lets us price.

Reviewers keep praising WP Super Cache for speed and easy setup, with only scattered complaints about a dated config screen, a dark-mode compatibility clash, and one runaway cache-file issue.

   Been running this for over a year on a few client sites. Configuration is a bit old-school compared to newer caching plugins, but it’s stable and rarely needs attention once set up.

   I’ve been using WP Super Cache for a while now and it has made a huge difference in my website performance. When properly configured, it turned out to be the best caching solution I’ve tried for WordPress. Page load times are significantly faster, server load is noticeably lower, and everything feels much more responsive overall. What I also really appreciate is that it’s completely free, yet still delivers performance that easily competes with many paid caching plugins. In my experience, it’s one of the most reliable and efficient caching systems available for WordPress. If set up correctly, WP Super Cache can seriously improve both speed and stability — definitely worth using.

   Tried this to improve my site speed and it actually helped. Pages load faster now and setup wasn’t too hard. Settings need a bit understanding at first, but once done it works nicely. pretty useful plugin.

   Everything seems to work well until I started using Astra Pro’s “Color Switcher” to implement “dark mode.” With “WP Super Cache” activated, my Color Switcher site appears unable to correctly “remember” whether the user has switched to the “normal” or “dark” mode. (E.g., load a webpage, toggle Color Switcher, navigate away to a different page on the same site, toggle Color Switcher again, then come back to the initial webpage … the page will load with the unexpected color palette; clearing browser cache and reloading/refreshing webpages in the browser do not help.) The issue goes away and “Color Switcher” works as expected as soon as I deactivated “WP Super Cache.”
