Feature limitations of FREE Self Hosted Edition

Sorry if this is a repost, but I am working 16 hours a day on this project and I am too tired to actually dig deeper.

In short, what are the limitations to the FREE Self Hosted Edition.

What sort of resources does it need on the VPS?

I am trying to deploy a FREE to use chat platform for the South African Public to use during the National Lockdown.

shows the differences between the three plans.

Thanks @dwaynem

I didn’t even bother to scroll down… need caffienne (and alcohol and nicotine which are currently banned during our lockdown)

I will read properly now and post again if I have further queries.

Just one to clarify on the 1K recommended (if I increase CPU and RAM can I go beyond that, or would a second peered server be required?)
