When phone calls are part of your workflow, compare AI voice agents by what they support: inbound and outbound calls, human handoff, and concurrent calls. Custom phone numbers and supported languages can help you assess their operating scope, while free-plan availability and paid-from pricing add cost context. The ranked entries begin with LiveKit Agents, Tone, and Rapida AI, with Yellow.ai and ElevenLabs also near the top. Check these details against the call directions, escalation needs, languages, and capacity you need to account for.
32 AI voice agents ranked on what their makers publish — plans and prices, free tiers, platforms and the facts on their own pages.
