Retell AI
The most granular, itemised pricing in the category — and the easiest honest cost model to audit.
Retell publishes a full component breakdown: voice infrastructure, TTS, each LLM, and every add-on priced separately. That is unusual and genuinely pro-buyer — you can model your real cost per minute before signing anything. It is also the most generous free start, with $10 in credits and 20 concurrent calls at no cost. The trade-off is that the headline '$0.07–$0.31/min' is a wide band, and your actual rate depends entirely on which model you pick.
ElevenLabs Agents
Best-in-class voice quality with the most predictable tier pricing — but low concurrency for campaigns.
ElevenLabs publishes a complete tier table from a free plan up to $990/mo, and $0.080/min is easy to reason about. Voice quality is the category benchmark. The problem for outbound specifically is concurrency: even the $990/mo Business tier allows only 40 concurrent calls, and exceeding your limit triggers burst pricing at double rate. For a serious outbound campaign that ceiling arrives fast.
