The short version

  • Only Elasticsearch has a free tier, so it costs nothing to try first.
  • Each has a real cost: Elasticsearch eventual consistency model with 1-second default refresh interval, not suitable for real-time transactional requirements; Zendesk aI agents operate on per-resolution billing; customers pay only when an AI agent successfully resolves a ticket without escalation
  • They diverge on capability: Elasticsearch covers Full-text Search, Zendesk covers Ticket management.

Elasticsearch

  • Eventual consistency model with 1-second default refresh interval, not suitable for real-time transactional requirements
  • No support for ACID transactions or rollbacks; updates delete and re-insert documents
  • JVM-dependent architecture requires careful memory management and monitoring to prevent garbage collection issues at scale

Zendesk

  • AI agents operate on per-resolution billing; customers pay only when an AI agent successfully resolves a ticket without escalation
  • Copilot and Contact Center features available as separate add-ons at £50+/agent/month
  • Advanced routing, workforce engagement, and approval workflows limited to Enterprise tier
  • Highest tier requires sales consultation and custom pricing
