Our take
Pick Stammer if you're agencies who will pay $49–$99 and mark up usage. Pick Vapi if you're a builder who want a voice agent with a Dashboard plus an API, and will pay hosting + provider pass-through. Skip Stammer if you're a developer who want a $0.05 / min API (Vapi). Skip Vapi if you're on a team that want one all-in per-minute rate with LLM/STT/TTS included (Bland).
