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; MotherDuck the free Lite plan caps compute at 10 hours per month, which limits it to light or hobbyist workloads.
  • They diverge on capability: ArangoDB covers Multi-model Support, MotherDuck covers Serverless DuckDB instances.
  • Prices and features above were last checked on 30 August 2026.
