The short version

  • Each has a real cost: ArangoDB the company has repositioned around a wider platform, so ArangoDB is now described as the foundation inside Arango rather than the product itself; IBM Db2 cloud-based Db2 is newer than mainframe version; some legacy mainframe features not yet available in cloud
  • They diverge on capability: ArangoDB covers Multi-model Support, IBM Db2 covers AI-powered Query Optimization.
  • Prices and features above were last checked on 30 August 2026.
