Glide as a business model for building apps

Firstly I think glide is a wonderful and inspiring tool and has certainly got me spending time thinking and learning about its potential.

I have a few burning and critical question to see whether I should be investing in this tool for use commercially.

Questions in my head

How many paid customers has glide got?

Has glide got a long term future or is this just a fad or trend?

What hosting does glide use? Class leading?

How secure is glide?

How often does the pricing model change?

What would happen if glide was not successful? How would I run the app/business? Code I download code so it could be hosted elsewhere or by another framework?
