Honest recommendations based on your situation
Vapi is developer-focused with extensive customization options and per-minute pricing ($0.05-0.15/min). Bland AI is more turnkey with enterprise focus, easier setup, and different pricing models. Vapi offers more flexibility while Bland AI prioritizes quick deployment.
Vapi typically costs $0.05-0.15 per minute depending on configuration. Bland AI pricing varies by plan and volume. For high-volume use cases, both platforms offer enterprise pricing. The actual cost depends on your usage patterns, voice quality requirements, and feature needs.
Yes, but migration requires development work. Both platforms have different APIs and configurations. Expect 1-3 weeks to migrate voice workflows between platforms. Consider building with abstraction layers to make future switches easier.
Both platforms support multiple TTS providers including ElevenLabs, PlayHT, and others. Voice quality depends more on your chosen TTS provider than the platform itself. Vapi offers more TTS options out of the box, while Bland AI focuses on their integrated voices.
Use Vapi for developer-heavy teams needing flexibility. Use Bland AI for faster deployment with less technical overhead. Build custom when you need full control, no vendor lock-in, and specific integrations neither platform supports. Custom builds cost more upfront but save on platform fees long-term.
