Some feedback:

- It's a very cool idea, and massive congrats on the launch!

- This has been done before, but a slick looking open source version is very cool! Have you looked at the concept of now pages, as this might lean into that? https://nownownow.com/about

- Personal dashboard builder is a poor term for this, as it implies a dashboard for personal data/usage.

- Link in bio is also a poor term, I suspect it's not a popular / well-known term. Personal Homepage is probably the best I can think of. Or now page perhaps?

- This GitHub readme says very little of substance, which gives me... "unfinished side project" vibes.

Best of luck with it!
