- Production-Ready: Multi-tenant architecture that scales to real-world call volumes
- No Hidden Costs: Open-source means no surprise billing or complex pricing tiers
- All-in-One: Web dashboard, analytics, and management tools included out of the box
- Self-Hosted: Complete control over your costs and data
- Beautiful UI: A web interface that actually works (unlike vapi.ai's notorious UI issues)
- Non-Technical Friendly: Manage assistants without deep developer expertise
- Complete Platform: Everything you need in one place, not scattered across multiple services
| Feature | Burki (Open-Source) | vapi.ai (Proprietary) |
|---|---|---|
| Latency | 0.8-1.2 seconds | 4-5+ seconds |
| Pricing | Free (self-hosted) | $0.07-$0.30/minute + hidden costs |
| Setup Complexity | 5-minute Docker deploy | Weeks of API integration |
| Web Interface | Beautiful, functional UI | Notorious UI/UX issues |
| Audio Quality | Built-in RNNoise denoising | Basic audio processing |

| Control | Full data ownership | Vendor lock-in |
| Transparency | Open-source code | Black box system |
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."
