Vapi current baseline
Vapi is an API-first voice AI platform: developers configure assistants (model, voice, transcriber) and either place/receive calls through Vapi's telephony or embed voice into web and mobile apps via SDK.
- Build, test, and deploy voice assistants via dashboard (no-code) or API/SDKs
- "Squads" for orchestrating multiple assistants in a single call flow
- Bring-your-own or Vapi-hosted speech-to-text, LLM, and text-to-speech providers
- Telephony integration for inbound/outbound phone calls plus web/mobile voice SDKs
- Real-time call monitoring, transcripts, and analytics
- Published starting point
- Usage-based (Vapi platform fee from $0.05/min on the Build plan)
- Setup
- 30m setup assessment
- Developer access
- API documentation, MCP documentation, OpenAPI specification
When to replace Vapi
Usage is metered per minute ($0.05/min Vapi platform fee alone, before model/voice provider costs), plus a $10/month charge per concurrent call line above the 10 included - so high-concurrency, high-volume deployments accumulate real infrastructure cost on top of per-minute AI provider billing. Compliance add-ons are priced separately and steeply (HIPAA $2,000/mo, Zero Data Retention $1,000/mo on top of the base plan), which prices out small teams that need those guarantees. Teams wanting a single fixed-price seat license rather than usage-based billing, or wanting a fully managed voice-agent product rather than an API they configure themselves, are not the target.
