How do Kayako and Zendesk Chat compare on features?
Kayako and Zendesk Chat compete in the same category but tune their feature sets for different team profiles. The material differences cluster around channel coverage, automation depth, reporting, and team management. The side-by-side below draws on aggregated G2 and Capterra reviews. A flat-rate alternative like Converge ($49/month for up to 15 agents) may sidestep the trade-off entirely.
Kayako provides journey-centric context per customer; Zendesk Suite provides operational breadth across channels — relationship context versus operational scale. Kayako's SingleView timeline shows every customer touchpoint chronologically. The knowledge base supports multiple languages. Automation rules handle routing. Guest collaborators contribute without agent seats. The single-plan model means every customer gets every feature.
Zendesk Suite bundles ticketing, Guide knowledge base, Talk voice with IVR, Explore analytics, and social channels. AI Copilot ($50/agent) assists agents. The marketplace has 1,500+ apps. Suite Enterprise ($169/agent) adds sandbox testing and custom agent roles.
Channel comparison: Kayako supports email, live chat, Facebook, Twitter, Instagram, and WhatsApp (on request). Zendesk Suite supports email, chat, phone, WhatsApp, Instagram, Messenger, X, and LINE. Zendesk adds native voice and LINE. Neither supports Telegram, Discord, or Zalo.
How much do Kayako and Zendesk Chat cost?
Kayako starts at From $1/mo (usage-based); Zendesk Chat starts at From $55/seat/mo (per seat). Converge is $49/month flat for up to 15 agents with all channels and AI included.
At 10 agents: Kayako One = $790/month; Zendesk Suite Team = $550/month. Zendesk is 30% cheaper at entry tier — but Kayako includes the journey timeline and AI resolutions that Suite Team lacks. Zendesk Suite Professional (10 agents) = $1,150/month — 46% more expensive than Kayako with HIPAA, SLAs, and advanced analytics.
AI comparison: Kayako charges $1 per AI-resolved ticket. Zendesk AI Copilot costs $50/agent/month flat. At 500 AI resolutions/month: Kayako adds $500. Zendesk Copilot for 10 agents = $500/month. Identical at this volume — but Kayako's cost scales with resolution count while Zendesk's is flat.
Kayako's recent company instability (ESW Capital/Trilogy acquisition, pricing restructuring) creates vendor risk that Zendesk's scale avoids. Both require annual billing for advertised rates.
