Aside: I get grouchy about the term "low-code", mostly because it's almost always a lie (you're going to need the code, and most "low-code" systems just hide how much that's going to hurt - which is why we put the code front and centre), and it causes people to lump Anvil in with, eg, Retool rather than, eg, Pynecone/Viola/Beeware...but this is definitely getting off topic ;)
Interested to hear how your scale-up/B2C users deal with the round-trip delays - I guess that's less of a deal with websites than interactive apps? (Should probably have grabbed you at PyCon to ask, but we were both pinned down pretty hard! I did manage to wave at you though, I think...)
