The SAP Architect's
Clean Core Accelerator
See a real ABAP program transformed
Three example programs, end to end: what each one is, what it does as a process, and what the engine turns it into. Every output below is a real transformation — verified, compiled and tested against Clean-Core Engine v2.7.0. Your own code goes through the same seven steps.
A sales operations team needs to query open standard orders (type 'OR') from SAP to populate a real-time order fulfillment dashboard. The legacy ABAP directly reads the VBAK database table — a non-released internal structure that breaks during S/4HANA upgrades. The engine transforms this into a clean CDS view consuming the released I_SalesOrder API, preserving the exact filter logic while making it upgrade-safe and unit-testable.

How a transformation actually runs
Upload, analyze, design, transform, test, document, deliver. Each step produces something you can read and check before the next one starts — and an architect signs the result, not the tool.
Deep Code Intelligence
Legacy ABAP is analyzed in seconds. Business rules, dependencies, and Clean Core compliance scores are extracted fully automatically.
What you can do today
Every feature listed here is live and free to use — start with 5 transformations or bring your own API key for unlimited access.
Extensibility Routing & Sign-Off
Classifies legacy custom logic against SAP Clean Core guidelines, routes between In-App RAP and Side-by-Side CAP tracks, and gates transformation behind an explicit architecture decision.
SAP Cloudification Catalog
Maps legacy objects against SAP's official Cloudification Repository — the same source behind SAP ATC checks — layered with curated field-level mappings. Weekly auto-synced, versioned, and audit-traceable.
Dual RAP & CAP Engine
Generates clean In-App ABAP Cloud RAP handlers or decoupled BTP CAP services. Powered by a deterministic evidence resolver that linearizes OO inheritance chains before translation, reducing structural AI hallucinations.
Modernization AssessmentNEW
Computes complexity and business-criticality scores, extracts a full code inventory, and maps data coupling with standard SAP table risk analysis — all before transformation.
Compliance & Audit Evidence
Visual compliance dashboard with exportable audit pack: input fingerprints, architecture decision records, model cards, and known limitations — ready for governance reviews.
BPMN 2.0 & Business Standard Operating Procedures
Maps modernized processes into standard BPMN 2.0 XML with swimlanes. Features a two-stage blueprint layer with Responsible-Accountable-Consulted-Informed (RACI) matrices, Level 5 Standard Operating Procedure (SOP) narratives, and internal compliance controls.
Your data stays yours
European hosting, designed to support GDPR-aligned processing and erasure workflows, with self-service data erasure control. We built the security architecture the way we'd want it for our own SAP systems.
Belgium Hosting (Europe)
Application storage and primary processing run in the europe-west1 GCP region (Belgium); AI and transactional-email subprocessors are disclosed separately.
DSGVO / GDPR-aligned
Art. 17 DSGVO erasure: purge all your uploads and data in Settings. Transactional emails are routed via the Resend API; subprocessors process data under their own terms.
Cloud-Native Security
Runs on Google Cloud Run with server-side encryption and stateless request handling — no persistent local data on the request path. Processing happens in managed, ephemeral containers.
Hardened Stateless APIs
Your BYOK API credentials are encrypted in transit, proxied securely server-side, and never trained or exposed to public LLM builders.
Community access
Every feature is included for free — no locked exports, no premium tiers. The only limit is 5 transformations; bring your own Gemini API key for unlimited runs. Both are 100 % free.
Free to use
Free for the SAP community — 5 transformations at no cost, or bring your own Gemini key (BYOK) for unlimited runs under your own terms.
Built on open standards & open data
Our object catalog is grounded in SAP’s Apache-2.0 Cloudification Repository, and your output is portable — standard abapGit and tests. You own what you generate. No lock-in.
Transparent by design
Every finding is tied to evidence and a source; coverage is shown per object — including the honest cases where there is no clean path. Belegt, nicht behauptet.
A complement, not a replacement
We accelerate the first assessment and draft. The architecture decisions — and the judgment — stay with you. An independent product, not affiliated with or endorsed by SAP SE.

Sandbox Only · Read-Only
Connections are restricted to non-production sandbox systems. Only OData metadata reads and test execution — no write operations, no production access.
