What is the cheapest Vapi alternative?

Vapi doesn't publish a price, so there's nothing to undercut on paper. Of the alternatives that do publish, the cheapest is Bland AI.

Why switch from Vapi?

The gaps buyers hit most: You build and maintain the agent yourself. The docs describe Vapi as "the developer platform for building voice AI agents" where you choose your own transcriber, LLM and voice from "dozens of providers and models", and the FAQ states that "for more advanced features like function calling, you will have to set up a Server URL to receive and respond to messages." There is no done-for-you setup service in the published pricing. The $0.05/min is hosting only. The pricing page labels it "Vapi Hosting Cost" and "Excludes Model Provider Costs"; STT, LLM and TTS are billed "At cost" on top, and the FAQ says "the vast majority of cost in running your application will come from provider cost (Speech-to-text, LLM, Text-to-speech) direct with vendors (Deepgram, OpenAI, ElevenLabs, etc)".
