- ✗Advanced integrations may require technical setup or support for complex enterprise workflows.

Vapi - Pros & Cons
Pros
- ✓Transparent usage pricing — $0.05/min plus BYO model keys is easy to forecast
- ✓Sub-700ms turn-taking feels conversational, not robotic
- ✓Provider-agnostic stack lets you pick best-of-breed STT, LLM, and TTS
- ✓Developer surface is solid: SDKs, webhooks, custom function calls
- ✓HIPAA and PCI options unlock healthcare and fintech use cases
Cons
- ✗Not a no-code product; non-developers will need engineering support
- ✗HIPAA at $2k/mo and ZDR at $1k/mo add up quickly for small teams
- ✗10 concurrent lines is fine for most pilots but extra lines at $10/mo scale fast
- ✗Model costs pass through, so a chatty agent on GPT-4 can be expensive
- ✗Documentation around advanced routing and warm transfers is still maturing
