Thanks for highlighting Zitadel!
We agree—Zitadel is a strong platform. Our main challenge as an infrastructure product is balancing flexibility with ease of use. While we offer a lot of adaptability for different use cases, getting started can be daunting. We're actively working to make our onboarding process smoother so users can get up and running more quickly. For example we just started working on a lot of improvements on our SDKs as well as a template login app in nextjs that people can fork.
