High removal-risk signals
63/100Maintenance and integrity signals that tend to precede a WordPress.org removal. Not an official status, a heads-up to act.
- Long abandoned. No update in 14+ years — the top precursor to removal once a vulnerability is found.
- Compatibility drift. Tested only up to WordPress 3.0.5, well behind 6.8.

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.
