Papi
Papi has a different approach on how to work with fields and page types in WordPress. The idea is coming from how Page Type Builder in EPiServer works and has been loved by the developers.
So we thought, why not use the same approach in WordPress? Papi is running in production today and has been easy to work with when it came to adding new fields and creating different types of pages.
