Does anyone use a cloud based RAD database other than Ninox - if so what? and how does it compare?

ie like Ninox - can you have forms over the tables. Can it be multi user. Can you do reasonable simple script?.

I have another major project that I want to do - but not sure if I want to do it in Ninox as I would like to see what other software can do before I make the decision.

Having user forms it the big thing thou....
