Tooljet IMO is the most promising of the open-source Retool competitors. It has a great UI, is easy to use, plugs into everything, and is super flexible. If you haven't checked out out lately, I highly recommend it.

Out of curiosity, have you tried Budibase? I'm the co-founder and would be interested to hear your feedback if you've tried it.
