PHP Compatibility Checker

How well this listing is tuned to rank in WordPress.org search, on the factors an owner controls. Not popularity, optimization.

Directory rank vs rivals

wp.org popularity rank over time · higher is better · when a rival's line climbs above yours, they've overtaken you

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

Share of active installs on each version of this plugin · 85% run the current release. Green is the current release; a big slice on older versions is a user base that has stopped updating.

Modeled within the band wp.org reports; tightens as we track daily.

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.

   Over the years, I have tried to be careful to not install programs that are not kept up to date. Yet, WordPress suggest that we install this outdated app that has not been updated for over 2 years. Many have reported errors. All just to test for the push that WP has for us to upgrade the version of PHP we are using. This doesn’t make sense!I had tried to put a link to where WP suggest this, but strangely the forums won’t even let me put a link to their own website.

   It hangs like many others say. No replies on the forum. You’re giving people false hope.Just get it offline and focus on your other plugins (which are working very well, btw); you’ll do yourself and many others a favor.

   ran the plugin on quite a few sites and most timeout after a couple of plugins are tested. Lots of false positives and errors. surely there is a better plugin out there?

   Useless! Gives a 404 error on plugins that ARE PHP 8 compatible. and then hangs. I’ve been waiting 30 minutes for it to unhang, and I finally gave up. It sure would be nice if this thing worked as advertised. Here’s what I got: MaxButtons Pro 9.5.5 Response status: 404 Message: The audit requested does not exist. Am I supposed to know what that means? How do I fix it? Right now it’s completely useless, and it hangs the software — never goes any farther to get to the rest of my plugins. Not a bit of help as is. This topic was modified 3 years, 2 months ago by elffuts. Reason: add more info about the error message

   Rates several themes and plugins as compatible, which definitely are not and have crashed under newer PHP versions (Random Text 0.3.0, WP Bakery 6.0.5, Slideshow 2.3.1 (dereg’d since Apr ’22)) — and has rated several themes and plugins as incompatible which seem to work fine under PHP 7.4 previous versions (Duplicator 1.5.3.1, LayerSlider WP 6.8.2, UpdraftPlus – Backup/Restore 1.23.3, WP Mail SMTP 3.7.0). So to have false evals of plugins and themes, both directions, makes this a useless tool and a waste of time. It’s a great idea of course, but with the errors I’ve seen it means it can’t even be relied upon to give some clues in a PHP problem hunt. If I’m missing something will happily change my tune — because like ChatGPT, it sure gives some attractive, confident-looking answers! And linting ought not be so buggy as all this. Truly quite surprised.

   Obviously the website’s current php is working or the website wouldn’t render. But you have no way to check future php versions and website compatibility. I wanted to see if my website would be compatible to PHP 8.0. This plugin redirects you to LocalWP …. whatever that is.
