Analytics Dashboard for SaaS

Hey everyone, I am trying to create an analytics dashboard for my clients. Want to know which framework/low code tool will help me start soon. I explored retool and Google Data Studio but none of them work so far.
Why not?
Retool - The UX is pretty bad. It's good for internal products but not client facing
Google Data Studio - It kinda fits the bill but there are too many errors and not much help.

Would appreciate if I do not have to code the whole thing. Thanks in advance.
