SaaS Feature Teardown Analysis

Is someone building a product or service that does a detailed teardown analysis of SaaS features, say by feature area?

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.

Is there a product that does this? If it did - how much subscription per month would you pay for it?
