Our take
Pick Retell if you're on a team that want a voice agent today and will pay minutes + add-ons, without an annual commit. Pick Roark if you're on a voice team who will spend the $50 credit, then $0.15 / min simulations. Skip Retell if you're buyers who want one all-in minute that already includes the LLM (Bland). Skip Roark if you're people who need a $100 flat eval seat (Coval Starter) or a prompt YAML (Promptfoo).
