About 6 months to switch - probably twice as long as it should have, because it was happening in parallel with maintaining and improving the no-code version, and the product requirements were evolving.

Switching off the no-code version was a happy day. We'd pushed it further than it was designed to go. The initial advantages of quick prototyping slowed down, and it was getting harder (very hard) to add new features without breaking old ones. Customizing the design (to our designer's high standards!) was... tough.

The coded version was better in every way - but part of that was because we learned a lot from the prototype. I personally probably wouldn't start a fresh project with it - but I would recommended it to (technical) non-programmers who want to get an idea out of their head to see if it's any good.
