About Clean-Core.io
A free, community-powered prototyping platform for SAP architects and developers.
The Mission
Clean-Core.io exists to solve one of the most expensive problems in the SAP ecosystem: transforming decades of custom ABAP code into cloud-compliant architectures. Instead of replacing the expert, we accelerate their work — generating the first Clean-Core-compliant draft for review and approval, saving days of manual mapping and boilerplate generation.

Felix Frenzel
Founder — Clean-Core.io
Felix is personally affected by an S/4HANA transformation and built Clean-Core.io out of that first-hand experience. What started as a tool to solve his own challenges quickly grew into a free resource for the entire SAP community — helping others navigate Clean Core compliance, legacy code modernization, and the complexity of S/4HANA migrations.
