Adalo General Questions

Hi all, I am new to Adalo so I have a few questions I would like to ask! Some of my questions may be simple but yeah, I’m fairly new to No Code!

How scaleable is an app that uses Adalo’s backend? Does Adalo use AWS? I read somewhere they were planning to switch to AWS but not sure if that’s happened yet?

I am based in the UK, if I was to make an app, would it only be available in certain regions or is there a way of expanding an app to more regions?

Also, I am more than keen on seeing what people have built on Adalo, feel free to share your apps so I can check them out, I am always interested in what people have worked hard on.

Thanks!
