Best for	Developers building custom voice agent products Startups automating support or sales calls Agencies deploying voice agents for clients	Developers building custom voice bots Engineering teams automating phone workflows Startups needing a flexible voice AI stack
Pros	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) Extensive integration directory including Twilio, CRMs, and calendars	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 Transparent pay-as-you-go pricing with no seat minimums
Cons	Headline $0.07/min rate is misleading; real costs run $0.13-$0.31/min Costs stack across LLM, TTS, and telephony, making budgeting complex Enterprise plan is expensive, starting around $8,000 Steeper learning curve for non-developers building advanced flows No permanent free plan, only $10 in starter credits	Headline $0.05/min excludes provider costs, so real cost is much higher Pricing is hard to predict and budget across multiple vendors Steep learning curve for non-developers No self-hosting option Extra concurrency and compliance features add cost
