RevolveR captcha more simple and helpful because it used pure javascript canvas render of captcha pattern that can't be read for now. It is require to repeat pattern with users draw.

I have create some obstacles for analyzing captcha generation data that goes from secure route via fetch request on every document update. This data is cryptic to spammer robots because them won't execute javascript. This data is low crypted with randomizing pattern pixels coordinates. Adds complexity and the presence of Roman numerals and shuffling data with latin alphabet.

This encryption simple and fast. It's not to brake client and does not provide the possibility of bulkheads. With RevolveR CMS not dependencies needed to use RevolveR Captcha. It was integrated in core.

Maybe later, when I have to create fully randomized patterns I may to create a new Captcha service that more user-friendly end fast than Google services to allow other CMS users use this Captcha.
