The Open-Source Alternative to vapi.ai That Actually Works Burki is the complete voice AI platform that delivers what proprietary solutions like vapi.ai promise but fail to provide.

​
Why choose Burki over vapi.ai?

Real User Experience: “I was a vapi.ai power user for 2.5 years. The UI never worked properly, latency was terrible (4-5 seconds), and their recent pricing changes would cost my startup $800/month. With Burki, I get sub-second response times and complete control over my costs.”

​

​
💰 Transparent & Affordable

  • No Hidden Costs: Self-hosted means complete cost control

  • Predictable Scaling: No surprise billing as you grow
