Really Simple CAPTCHA

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

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. Green is the current release; a big slice on older versions is a user base that has stopped updating.

Refined from the date this plugin crossed into its current band.

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. The recent download trend is too spiky to read.

   Easy integration and locally usable in contrast to most captcha options out there, who will be sharing data to external servers. Wonderful for building a small obstacle for bots in a conform way for GDPR. Thanks!

   I’m sorry to have to give this a bad rating. The amount of spam with Contact Form 7 was enormous. I had to remove it.

   Nothing but positives. We added this to our Gravity Form in order to obtain the dynamic math captcha. One can create a simple math captcha in GF but not dynamically changing for each form load insofar as I can determine. And GF google captcha Ver 3 is a pain with the need for google api keys. So we added this plugin and it was very easy – add the captcha field to the form, select “math” in the settings for the field and done! We find that Gravity Forms Zero Spam plugin was helping to deter spam entries but it with this captcha is 100% so far for spam prevention. Thank you Takayuki Miyoshi!
