Pick ONOXIA if EU data residency is non-negotiable, you want voice input and live handover as part of the platform rather than as integrations, and you serve customers in multiple languages where bot quality matters (28 supported, auto-detected per visitor).
Pick Chatbase if you are a US team comfortable with OpenAI processing, want the lowest entry price, and do not need handover, voice, or email-agent capabilities.
ONOXIA routes inference through Mistral AI in Paris for European traffic — a sovereign EU AI provider — and through Qwen or Gemini for Asia-Pacific. Chatbase uses OpenAI for all queries, meaning every visitor message and every retrieved document chunk traverses OpenAI's US infrastructure. For a customer who has spent six months getting their auditor to sign off on a "no transatlantic data transfer" position, this is a hard constraint, not a preference.
ONOXIA ships voice input, Calendly booking, live human handover, an IMAP/SMTP email agent, and 28 languages in the platform. Chatbase delivers a focused RAG chatbot with webhooks; equivalent capabilities require third-party integration work. Both are valid approaches — ONOXIA bets that customers want a complete out-of-the-box widget; Chatbase bets they prefer a slim core and external glue.
