Alternatives may fit teams that need voice alongside video, text, chat widgets, visual bot design, self-hosting, private-cloud deployment, or local AI systems. Vapi's free-start package allows four concurrent calls and 14 days of raw-data retention; Core raises those limits to 10 calls and 30 days. When switching, weigh deployment control, supported modalities, provider choice, knowledge sources, workflow connections, observability, handoffs, collaboration features, and pricing. The options below emphasize where each product differs and when that difference may matter more than Vapi's broader voice-agent stack.
