## FAQ

**What is the best alternative to Pipecat?**
It depends on whether you'd rather self-host or buy a managed product. LiveKit Agents is the most widely-adopted open-source alternative (14k GitHub stars); Bland AI is one of the commercial options. Compare the full list above on adoption, license, and pricing.

**Is there a free or open-source alternative to Pipecat?**
Yes. LiveKit Agents, Starmoon, and xiaozhi-esp32-server are open-source voice agents you can self-host for free — you still pay for the infrastructure you run them on and any model or API usage. See the ranked open-source list above.

**How are these Pipecat alternatives ranked?**
Every product in the voice agents category is a candidate. Open-source alternatives are ranked by maintained adoption — GitHub stars plus recent commit activity — so you see what's genuinely used, not abandoned. Commercial products are listed separately and alphabetically, because stars don't measure commercial adoption. Sponsored placement is always labeled and never affects the ranking.
