Our take
Pick Bolna if you're a builder who will top up $10–$500 and stay on preferred models. Pick Stammer if you're agencies who will pay $49–$99 and mark up usage. Skip Bolna if you're on a team that want one US all-in rate with no wallet math (Bland). Skip Stammer if you're a developer who want a $0.05 / min API (Vapi).
