  • Each has a real cost: Kayako the AI agent is billed at $1 per resolved ticket, so support cost scales with ticket volume rather than being a fixed subscription; Rasa free Developer Edition caps conversations at 1,000 external or 100 internal per company per month
  • They diverge on capability: Kayako covers Unified inbox, Rasa covers NLU engine.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Kayako

  • The AI agent is billed at $1 per resolved ticket, so support cost scales with ticket volume rather than being a fixed subscription
  • A resolution counts when the AI solves the issue without human involvement, so the definition of a billable event is set by the vendor's own system
  • No per agent monthly price is published for the full Kayako One platform
  • Full platform pricing requires talking to an expert

Rasa

  • Free Developer Edition caps conversations at 1,000 external or 100 internal per company per month
  • Rasa Pro and the Business Plan (Pro plus Studio) are not priced on the site and require contacting sales
