How This Compares
Not every migration path looks the same. Here's what to look for when you're evaluating one.
Dimension
API Modernizer
Typical approach
Where your code runs
On-premise or air-gapped — your source code, generated artifacts, and data never leave your environment. No upload, no third-party cloud, no third-party LLM, no sub-processor.
Often uploaded to a vendor cloud or passed through a third-party LLM — worth confirming exactly where your source goes and who processes it.
Validation before cutover
Your own existing tests run field-by-field against both systems, scored MATCH or MISMATCH, before anything is decommissioned (Proven-Parity Migration).
Often relies on trusting the migration output, or on generated test scaffolding and mocks rather than a systematic response-by-response comparison against the real source system.
DataWeave
Translated automatically, including complex and recursive transforms; anything untranslatable is flagged inline with the original preserved.
Simple transforms handled; complex or recursive DataWeave is often handed back to your engineers to reimplement by hand.
Vendor lock-in after migration
Runs entirely in your own environment with no calls home. The embedded Transmute engine that runs your DataWeave is bundled with your project and included at no separate or ongoing licence — you leave Anypoint licensing without swapping it for a new subscription.
Worth checking directly — some generated output depends on the vendor's own runtime or emulation layer to keep working.
Commercials
Estate-scoped engagement — try it on one real app and keep everything, with no long-term commitment.
Often a broader commitment is required before you see results on your own code.
Security & compliance disclosure
Stated precisely: controls implemented today are described as implemented; certifications in progress are described as in progress.
Certifications and controls are sometimes referenced without detail on current status — worth asking for specifics.
"Typical approach" describes common patterns in manual migrations and enterprise integration tooling generally, not any specific vendor. Confirm current details directly with any vendor you're evaluating, including us.
See it against your own application
The fastest way to evaluate any of this is on real code, not a comparison table.
