Mobbin launch curated collection of A/B test results from best-in-class apps

The makers of Mobbin (a site that curates screen flows from some of the best apps and web apps) have launched https://abtest.design/, a site to showcase A/B tests and their results.

Some examples include TikTok's delayed bank account setup leading to a 25% increase in creators enrolling in the program, and Mural's Onboarding checklist
that lead to a 10% increase in 1 week retention.

As far as I can see, all featured tests seem to have led to positive changes in metrics, so there's probably a bit of confirmation bias at play here because companies/makers might be more likely to showcase what worked well.

But still seems like a good resource.

Do you have any other go-to resources for A/B test case studies?
