The Platform for MuleSoft Modernization

Runs In Your Environment

Your Code Never Leaves

Deploy API Modernizer on-premise, in your VPC, or fully air-gapped. Your Mule source, the generated Spring Boot project, and your data stay inside your infrastructure — no upload, no third-party cloud, and no third-party LLM in the conversion path. Nothing to send, nothing for a vendor to store, and no sub-processor to add to your security review.

Automated Conversion

From Mule XML to Compilable Spring Boot

API Modernizer parses your entire Mule 4 application — flows, error handlers, scatter-gather, DataWeave scripts, connector configurations — and generates a production-quality Spring Boot Maven project. Every @RestController. Every connector bean. Every DataWeave script translated. Complete pom.xml. A MANUAL_FIXES.md for the small percentage that needs human review. A README.md with run instructions. Run mvn package and deploy.

DataWeave, Preserved

Your DataWeave Keeps Working — No Rewrite

DataWeave is the biggest migration challenge — 60–70% of migration effort in typical programmes — and it's where a risky rewrite does the most damage. So the converted app doesn't rewrite it: your DataWeave runs on the embedded Transmute engine, a DataWeave-compatible engine bundled with your project, as editable scripts (map, filter, reduce, groupBy, mapObject, error handlers, type coercions) your team already understands. Anything it can't translate is flagged with the original preserved inline. Optional DataWeave-to-Java transformation, for teams that want to leave DataWeave behind entirely, is on the roadmap.

Proven-Parity Validation

Proof, Not Promise

Every other migration tool asks you to trust the output. API Modernizer proves it. Your existing Postman collection runs against both the original Mule app and the converted Spring Boot app simultaneously. Responses are compared field-by-field. MATCH/MISMATCH per endpoint. Before you decommission anything.
