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 6+ years — the top precursor to removal once a vulnerability is found.
- Compatibility drift. Tested only up to WordPress 5.3.23, 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
A small install base leaves thin data to model from. The range spans more than 10x because wp.org publishes install counts as broad bands, and conversion and price compound on top. Read the midpoint as an order of magnitude, not a valuation.
How we estimate this
Assumptions
- Free → paid conversion. 0.5%–2% of active installs pay for the pro tier. Typical for freemium WordPress plugins; the real rate varies a lot by product.
- Annual price per customer. $79–$199 a year, typical for Booking & Events plugins rather than this plugin's own pricing.
- Acquisition multiple. 2.5x–4.5x annual revenue, the going range for small WordPress-plugin businesses, stretched a little because downloads are growing.
- Install base. 10–20 active installs, from our install estimate (wp.org only publishes the floor).

Revenue is installs × conversion × price; value is revenue × a typical acquisition multiple. Every factor is an assumption band, so the output is a wide range on purpose. If you're buying or selling, treat this as a starting point for due diligence.

Does not work. I fill in the event, save it, but don’t show it. It is a pity. He looked great. This topic was modified 6 years, 3 months ago by Branike.
