This was unique among builders I've reviewed, but not especially interesting.

The canvas builder itself is a bit complex and a little buggy, but it seems to have all the customization you need.

You have a database system built in, and a few other features, but it's not something I'd use myself.

I did like that the free tier was generous, and the pricing was based on usage. If you're not using a lot of resources, or working with a lot of users, it's cheap.

It's a little more designed for people that understand code, but it's definitely usable for someone without tech experience if they give it time.
