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
No release in a yearHow 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
Est. acquisition value
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. A declining trend compresses what a buyer would pay.

Installed plugin, added one domain to the blacklist, then used an incognito window to attempt to register, using an email address with the domain in question – and it let me right in. Sounded great, but unfortunately, it didn’t work as expected.
