Pros	Strong focus on ultra-low latency High-fidelity, natural-sounding speech SDKs for web, phone, and game integration Free way to get started Usage-based, granular pricing	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
Cons	Small, bootstrapped team with limited headcount Public pricing tiers are not clearly listed Larger deployments appear to be talk-to-sales No self-hosting option Limited business/collaboration features	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
