This is a good point. Most comments about the rewrite in code being easier might actually be because the functional requirements from the business users have already been made clear without the ambiguity that might have arisen when developing from scratch.
In this case, this is absolutely true. All the requirements were well established and converting it was very quick because of it. But ultimately that doesn't matter because the reason the re-write was done was because the no-code solution failed in it's goal.
The process of developing this solution was funny. We had an absolutely fantastic team doing the requirements and the process was all agile except when it came to the tool itself. At that point, it turned into a waterfall project where everything had to be nailed down before the work was done.
I can mock up a application form very fast so there's really no need for a tool to do that every so slightly faster but in a proprietary and limited way.
