SaaS teardown for efficient feature development

Hi HN!

While building SaaS products, I always end up wishing that there was a product or service that could provide me with a teardown analysis of specific feature areas from popular SaaS products out there.

For example, if I'm building a "Team" feature, I want to know how have other products have implemented it. How does the workflow look like? UI? UX?

There are probably thousands of other products that have built and implemented the same feature, so seems kind of inefficient that I have to reinvent the wheel every time.

Do you know if there is an existing product or service that already does that?

If not, and I built it - would you pay for it? How much per month?
