Common questions
Is Vapi free to use?
Vapi is open source and free to run yourself. You still pay whichever model provider you point it at, and this tutorial is free with no signup.

Basic Python is enough. Functions, dictionaries and imports cover most of what Vapi asks of you.
When should I not use Vapi?
