I’m an experienced developer backed by some far more experienced ones (like having 35-40 years in software development).

We are trying test Anvil to see if it really fits all of our needs.
(Gonna take 3-4 months to run several tests since the whole system - much larger than just using Anvil - should also planned and several other tools created. Creating of those tools consumes much more work than creating an Anvil app. But these are necessary to create Anvil apps - or anything else - fast and full. The fully system requirements were made only at the top level and to test Anvil we need to go much deeper and work out a lot of details for the final system.
On the other hand, with any software products for wide use, the first 3-4 months must be just the testing phase in order to make reliable products.)

In terms of Anvil we are testing different features and trying to implementing missing ones in order to make simple web development for our apps.
Week by week we are making progress.

Our experience with Anvil is really positive and we can offer it for anyone else (even very large companies).
Compared to anything else, it is simple and yet feature packed.

We’re gonna see in a few months where it goes. We assume that everything will go well during this testing phase. Literally, a few hundred thing will be tested over time, repeatedly and see if it works perfectly.

There are no other tools like Anvil.
It is a lucky choice.
Congratulations for Anvil staff and the Founder(s).
