Our take
A solid build-your-own voice-agent platform with refreshingly transparent per-minute pricing and no forced subscription. Budget for the full stack though: telephony, the LLM, and TTS push real costs to roughly $0.13-0.31/min, well above the $0.07 headline rate.
Best for
Teams with some dev resource building inbound or outbound phone agents who want usage-based pricing.
Pros
- Transparent per-minute pricing with no mandatory subscription

Cons
- Real cost ($0.13-0.31/min) is well above the $0.07 headline
