Retell AI vs Alternatives — Quick Comparison
Top Retell AI Alternatives, Explained
1. Vapi
4.5· Usage-basedVapi orchestrates real-time voice conversations: speech-to-text, the LLM, text-to-speech and telephony, with turn-taking and interruption handling. It has the widest choice of models and voices and a strong developer API. The $0.05 per minute platform fee covers orchestration only. Models are billed at cost, or $0 if you bring your own API keys, and telephony is billed by your provider, so real all-in costs land around $0.12 to $0.33 per minute depending on the voice and model you pick (prices as of August 2026).
- Widest model and voice choice
- Strong developer API
- $0 model markup with your own keys
2. Bland AI
4.3· Usage-basedBland AI runs automated inbound and outbound phone calls at scale. Its main selling point is pricing you can predict: one all-inclusive rate of roughly $0.09 per minute covering the platform, voice and LLM, which lands around $0.09 to $0.14 per minute with telephony. It suits teams that want a simple number for high call volumes over the most model choice. Enterprise plans add dedicated infrastructure and custom models (prices as of August 2026).
