The short version

  • Each has a real cost: Neon compute pricing at $0.106-$0.222/CU-hour means costs scale directly with workload, unlike fixed-price alternatives; Zilliz pricing structure not publicly disclosed, requires sales contact
  • They diverge on capability: Neon covers Serverless PostgreSQL, Zilliz covers Vector indexing.
  • Prices and features above were last checked on 30 August 2026.
