Why Teams Switch

Why Teams Choose Scalix Prime Over Neptune

⊕

Deploy Anywhere, No Lock-In

Neptune ties you to AWS VPC. Scalix Prime deploys on-premise, in your datacenter, air-gapped for defense, or across multiple clouds. Your data stays where you choose — not where a cloud vendor decides.

↔

Graph + Relational, One Engine

Neptune is graph-only — you still need DynamoDB, RDS, or Redshift for relational workloads. Scalix Prime unifies both in one C++20 kernel. SQL and Cypher in the same transaction, zero data duplication.

☆

Built-In Intelligence

Neptune has no ontology system, no schema drift detection, no code intelligence. Scalix Prime auto-evolves your data model, ships with HL7 FHIR and MITRE ATT&CK ontologies, and includes a 12-phase code analysis pipeline across 6 languages.
