AiFlow vs Vapi
A developer-first voice platform that assembles speech to text, a model, text to speech, and telephony into one API.
Their Pricing Model
A platform fee of about $0.05 a minute, plus each component of the stack billed separately.
Architectural Crux
You assemble and pay for the stack, and then pay Vapi a fee per minute for orchestrating it. Both meters run forever.
Where each architecture wins.
Where Vapi has the advantage
- Nothing to host. You are making calls the same afternoon.
- A larger catalogue of speech and voice providers to mix and match.
- A bigger community and more third-party tutorials.
Where AiFlow has the advantage
- One payment rather than a fee on every minute for the life of the product.
- Conversations stay on your infrastructure and never reach a vendor.
- Camera and screen share inside the live conversation.
- MCP in both directions, so AiFlow is also a tool source for other clients.
Which one should you choose?
Choose Vapi when:
You want to be live today, your volume is modest, and sending conversation audio to a third party is not a problem for you.
Choose AiFlow when:
Volume is growing, or your data cannot leave your own infrastructure, or you would rather own the thing than rent it.

How we calculate this
Using the comparison rates stored in this project: Vapi at $0.05/minute. Excludes model, telephony, hosting, taxes, and operational costs. Vendor plans and inclusions differ; this is a platform-fee estimate, not a full operating-cost quote.
