Questions, answered

Who is behind bolna?

The project lives at bolna-ai/bolna and has attracted 370 forks. Browse its commit history and contributor list for a sense of maintenance pace.

Is bolna free to use?

Yes - it is MIT licensed, so you can use, modify, and distribute it freely, including in commercial projects.

Do I need a paid API to use it?

The framework is free, but voice agents need speech and model providers, which usually bill per minute or per token.

Bolna vs Vapi's SDK?

Bolna is an open-source voice agent framework you self-host; Vapi's SDK connects to Vapi's hosted voice platform. Choose Bolna for open control, Vapi for managed infrastructure.

Where should I start?

The README and the official docs site are the fastest path: run the quickstart example first, then adapt it to your use case.
