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.

Release cadence

Actively maintained
from wp.org release tags

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

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

N/A

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.

    We lost customers because their mail address was marked as invalid and the order couldn’t get through. They sent me a mail from that address proving that the address did actually work. We immediately uninstalled this plugin, it’s not trustworthy.
