If engineering time is free for you, Vapi wins on paper. If an afternoon of developer time costs real money, the gap closes fast, and someone still has to answer the pager when a provider changes an API.
On KiwiAgent Business and Enterprise you can bring your own OpenAI or Anthropic, ElevenLabs, and Twilio or Telnyx keys. You pay providers at cost, exactly like Vapi, and we charge $249/month plus a flat $0.19/min platform rate to run everything for you.
See BYO pricingOn raw usage, often yes. Vapi charges about US$0.05 per minute for hosting plus provider costs at cost, so a technical team can run minutes cheaply. But you assemble and maintain the agent yourself: telephony, speech recognition, the language model, the voice, prompts, and integrations, all billed separately in US dollars. KiwiAgent's NZD rate includes all of that plus setup done for you. If your time is free, Vapi is cheaper on paper. If it is not, it usually is not.
Yes. On the Business and Enterprise plans you can connect your own OpenAI or Anthropic, ElevenLabs, and Twilio or Telnyx accounts. You pay those providers directly at cost, and Business drops to $249/month with a flat $0.19/min platform rate. That gives you Vapi-style cost control with done-for-you operations.
Yes, Vapi is a global developer platform and you can attach NZ numbers through providers like Twilio or Telnyx. You handle number provisioning, NZ-accent voice selection, and local business context yourself, and billing is in US dollars. KiwiAgent includes NZ numbers, Kiwi-accent voices, and NZD invoices with GST by default.
Choose Vapi if you have developers and want to build a custom voice product with full pipeline control. Choose KiwiAgent if you run a New Zealand business and want your phone answered well this week, with setup, support, and billing handled locally.
