Google reCaptcha - Number of Hits per Day

Question

I am using Google reCaptcha in a Angular+Spring MVC application for user signIn. I would like to know if Google has any restriction on the number of hits it supports per day ( or week/month/year).

Answer 1

First, I advise you to read FAQ

To answer your question; (according to v1.0)

Does reCAPTCHA have the capacity to accommodate large amounts of traffic?

Definitely. reCAPTCHA has distributed locations and multiple servers. The only thing we ask is to be contacted beforehand if you expect your site to constantly need more than 1 million reCAPTCHAs solved per day. reCAPTCHA is used by many large sites — we display over 100 million CAPTCHAs every day.

I have also tested it (on v2) personally like a year ago, never had a problem with hundreds of thousands of requests and thousands of concurrent requests. So I think v1 answer is still valid or a lot flexible.
