Good point about supporting frontend platforms like Glide! And indeed it is quite close to what I am building: https://www.xano.com/technology/ and it seems that they are doing it with funding too "Xano has raised a total funding of $15.4M over 3 rounds from 2 investors".

What I don't like about Xano is integrating database tightly, which basically means that the data is hosted by Xano. I don't know if this is required or not. Many of the BaaS platforms do this, but I prefer just connecting and processing data and not hosting data.
