I guess the problem is that you dont have a competitive moat. It's too easy for your users to just take the code, find their own developers and host it themselves.
So a nontechnical user can basically mock up what they want and a backend dev can touch it up and get it production ready without having to slog through all tedious model and handler writing and can focus on non-solved problems.
This is already a workflow that works relatively well in big data stuff - analyst makes a dashboard with some spark queries, which work but are slow and inflexible, data engineer tweaks into a production-ready pipeline and data warehouse view using more professional-level code.
The vast majority of stuff where you just log users in, sell some stuff or subscriptions, and collect payment is already done with tedious identical piles of Django and Rails code anyway.
You would because you can without a subscription. If no code tools were free we might see different uses, but I really can't see people who can code paying for tools like this.
