Where App Engine fits
Choose App Engine when ServiceNow is the system of work and apps must live next to Now Platform workflows and data.
ServiceNow App Engine is strongest when a company already runs ITSM and enterprise workflows on the Now Platform and wants custom apps next to that data. Relpin is for teams that want internal tools as real TypeScript or Python code, promoted through deterministic release gates, and isolated on dedicated Postgres.
same artifact in every environment · fails closed on schema drift

Instance-to-instance publishing from development to test to production.
DEV → TEST → PROD gates: TEST needs 1 approval, PROD needs 2 with separation of duties.
Platform tables close to CMDB, ITSM, and workflow data.
Dedicated Postgres per org with server-side SQL and publish-time gates.
Platform audit and history features configured per table and instance.
Append-only, row-level audit with field-level before/after diffs and actor.
Choose App Engine when ServiceNow is the system of work and apps must live next to Now Platform workflows and data.

ServiceNow App Engine → Relpin
Every publish canonicalizes the app bundle to stable JSON and hashes it. The result is an immutable record pinned to exact platform and schema versions, promoted through approval gates, and bound to its own hash.
