This looks really really cool.

In the 90s we had RAD tools like Delphi or Visual Basic which allow you to create simple apps very quickly. I feel that we are missing RAD on the web these days. There are so many different moving pieces. To do a full modern web app you need to learn different languages and frameworks plus other technologies for hosting such as containers or AWS, etc. That might work for complex apps, but sometimes you just want to do something simple that you can easily design visually, use one language and hit one button to publish. I have the feeling that Anvil is moving in this direction.

And extra love for using Python :D
