Hello. Is “Simple Captcha” plugin the best way to implement Captcha (or  
similar functionality) in Rails?

Thanks.

I use the re-captcha plugin which works very well. eg it will  
seemlessly cope with no javascript etc.

I haven’t used Simple Captcha.

I’ve used it a few times & it all seems to work.

I’ve included tests in my code, so if it break upon a rails update, I  
will know about it before it hits production.

You should also check out “negative capcha” it is invisible to user  
and offers a better experience. I have a few sites using this and I  
think its worth a look too:
