Our take
Pick Roark if you're on a voice team who will spend the $50 credit, then $0.15 / min simulations. 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 Roark if you're people who need a $100 flat eval seat (Coval Starter) or a prompt YAML (Promptfoo). Skip Vapi if you're on a team that want one all-in per-minute rate with LLM/STT/TTS
