I'm trying to find out how many requests per second for data, and how many push notifications per month can be made under the free version. I don't see it on the pricing page, can anyone tell me what these are?
There are no limits on these items. Assuming the app is being used for legitimate purposes and is not intentionally subverting our terms of service, then you can send an unlimited amount of emails / push notifications / data requests. The number of environments / users / business logic that you use on your application is what dictates what customer class your account falls into.
