Would You Pay for a Custom Analytics SaaS or Just Use Google Analytics with a Better UI?

Hey Huzzlers....

I'm building an analytics SaaS and I'm currently stuck between two paths. I’ve already built a solid tracking system of my own — I can track pageviews, user behavior, sessions, etc.

But now I'm wondering if I should continue building everything from scratch (custom heatmaps, user journeys, screenshot-based session previews, real-time tracking), or instead just integrate with Google Analytics via their API.

The idea with GA is users would connect their account, and I’d display all their data in a cleaner, more focused UI with some extra insights layered in, like a 3d world globe with live users, a screenshot generator loaded with required features to Generate stats and share on your X profile and some more.

Easier for me, less infra to manage — but also feels less valuable since GA already gives that whole data.

So I’m torn: do you think indie founders would actually pay for some unique features I described, cleaner, easier-to-use UI on top of their GA data? 

Or is the real value in having a full custom tracking system where I own the data and the experience?

GA has trust and coverage, but it’s bloated and confusing. My tracker is lightweight, focused, and can be tailored to founders' real needs — but it’s more work and I’m unsure if people would make the switch.

Curious what you'd do or prefer.
