Is this possible to use recaptcha without internet connection

Question

I'm working on core php. I want to use recaptcha for my form. I downloaded recaptcha from this link. It works fine but when I switched off my internet connection it's invisible on my local.

Is it possible to use recaptcha on my local server?

Answer 1

https://www.google.com/recaptcha/api.js is the reCaptcha js controller that makes all the reCaptcha management. It is loaded from google server once and you might pre-load it and plug in locally. Yet, all the verification is done server-side by google, so you can't actually click recaptcha off-line, nor verify human-bot, neither submit a form.
