CMS collection limits

Hello all,

I am designing a website that requires cms, but won’t be launched until Aug 2021. Until then we are just going to keep it in development. While we don’t pay for hosting, and are working on it. What are the limitations to the CMS? like how many collections can we use, and how many items in each?

Thanks in advance
