Vapi pros and cons

Full control over the voice stack (STT, LLM, TTS, telephony)
Low-latency, near-human real-time conversations
Flexible REST API and official SDKs for any language
Advanced features like Squads, function calling, and RAG
Note: Headline $0.05/min excludes provider costs, so real cost is much higher
Note: Pricing is hard to predict and budget across multiple vendors
Note: Steep learning curve for non-developers

Retell AI pros and cons

Transparent per-minute, pay-as-you-go pricing with no platform fee
Full feature access from day one, nothing locked behind higher tiers
Strong developer tooling: API, testing/simulation suite, webhooks, functions
Wide model and voice choice (GPT, Claude, ElevenLabs, Retell voices)
Note: Headline $0.07/min rate is misleading; real costs run $0.13-$0.31/min
Note: Costs stack across LLM, TTS, and telephony, making budgeting complex
Note: Enterprise plan is expensive, starting around $8,000
