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

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 declining trend compresses what a buyer would pay.

I love CMB2. I love hooking into functions and extending addons so fields update each other intelligently, while locking out non-admins to sections. Blocks are great, don’t get me wrong, and the extensions to make the, more hookable and meta-integrated is nice, but CMB2 gives you full and complete control, with API documented and dozens of add on plugins out there. Using FacetWP? We have an add on! Need to attach posts? We have an add on? Want to use Shadow Taxonomies to connect posts instead of attaching them and somehow manage to do so dynamically and speedily? Hey buddy. They’ve got you. The power is yours to command. Seeing even a version-matching-tested-up-to update makes me worry far less that this plugin will fall by the wayside. Up next? PHP 8 compat (I hope…)
