I would use it only if I could be able to see/edit the source code. Sometimes it's vastly more simple to write 2 lines of code than construct a thought with drag and drop logic. For some Ux inspiration you might want to check out gdevelop. Its game creation software but uses drag and drop logic with slots for wiring things up. Kind of like a simpler scratch.

I'm an indie dev who doesn't make any money from my side projects so pricing is always a factor as well. Read: I always use a free tier.
