I'm using Quixy (https://quixy.com) for business process and workflow automation and it works great. They are a startup. The customer success team I work with is knowledgeable, and always willing to help. I evaluated Kintone before using Quixy and found workflows handled much better in Quixy.
Retool, I've been testing for internal usage at the company I work at and came away deeply impressed. Only drawback is the price because we need it on-premise. If not for that, it would be a no brainer, I'd pay it from my own pocket.
