Hits and CPU usage are not interchangeable. They are different limits that are affected in different ways. At the very least, if you ask for help, make sure that the information you provide is accurate. It’s fine if you don’t know, but if you tell us you reached the hits limit when that’s not actually the case, you’re undermining our ability to help you by feeding us false information.
No, I cannot confirm that.
None of these features violate our terms of service, but I cannot make any guarantees that you won’t hit any account limits with it. There is simply no way for me to predict how much resources your website will use.
I don’t have experience with most of the plugins you listed, and I don’t know how they are implemented. I can say something about general categories of plugins and how they can affect resource usage, but that doesn’t mean I can give you a full bill of materials given a list of plugins.
Also, website functionality is only half the story of resource usage. You’re completely ignoring the other half: traffic. Grossly simplified: account resource usage is equal to the resource usage per page multiplied by the number of page views.
The only way to know whether your website will hit the limits is to deploy is, let traffic come in, and watch the metrics. Only with prior experience with your exact site with your exact traffic can let you make estimations that are any good.
If you want a confidently wrong answer, feel free to ask your AI to give you an answer. It’s probably more accurate than I can be.
No, it’s only for free subdomains.
