Update activity

How busy the existing users are, measured as downloads in the last 30 days for every 1,000 active sites. A spike means a new release everyone's pulling; a long, slow decline means an aging user base that updates less.

Estimated value

What this plugin might earn a year, and what it might sell for. Modeled from public signals; we don't see anyone's books.

Est. annual revenue

Est. acquisition value

N/A

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. A small install base leaves thin data to model from.

    Most of my customer sites use multiple caching plugins. Customers get confused about different buttons like “Clear cache”, “Flush cache”, “Empty cache” etc.This plugin solves that!Besides, you can set automatic clearing on a lot of different hooks, even for CPT’s and Forms. The support is at lightning speed, a request for support of another caching plugin was developed within a week! Thank for this brilliant plugin Kevin.

    We use this plugin on over 150 sites to keep caches cleared, including Cloudflare. Been working great, had an issue briefly, associated with a particular “unusual” hosting platform. Asked developer about it and he fixed it within a week! Plugin clears all kinds of caches: OP cache, object cache, server caches. If you’ve been using the Cloudflare plugin to keep that cache cleared, particularly when developing, you won’t need it anymore as this plugin communicates directly with Cloudflare via API. Highly recommended plugin; invaluable in this day where we have multiple caches that can cause issues with maintaining fresh data for clients.

    Massively buggy. A bunch of cdn image try to load at the admin settings page and it loads and crashes right away. i finally got that to stop by just removing the cdn stuff from the plugin file and then found there isn’t actually a setting for bluehost :/big waste of time. but a good idea in theory.

    Now, we got the option to purge selected type of cache only. The plugin developer swiftly updated the plugin with required features.

    This plugin, in tandem with WP Rocket on WordPress.com hosting (Business Plan), does a deeper and more effective purge of my site’s cache. Sure, WP Rocket has its own purge, but it does not go as deep. This plugin really does assist in making things right. Thank you 🙏

    I have been using this plugin for over 18 months and it does eactly what it says on the tin! About 4 weeks ago It stopped working due to server upgrades on my web hosting platform. The developer was very quick to respond to my issue and helped me through a minefield to the point where it is once again working. If you need your Cache purged on a regular basis…look no further
