Removal-risk signals

53/100

Maintenance 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 5+ years — the top precursor to removal once a vulnerability is found.
  • Falling behind WordPress. Tested up to WordPress 5.7.17.

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

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.

    Реально работающий плагин. Без настроек. Поставил и забыл о нём.
