Vapi
Vapi is a hosted voice-AI agent platform that builds, deploys, and monitors phone-call agents with packaged tiers, SSO and compliance options, per-minute transport/model billing lines, and add-ons for extra concurrent calls and numbers.
The site lists a usage-only option plus three named success packages: No Success Package (usage-first), Core ($29 / month), Pro (listed at $999 with additional fees), and Premier (contact sales). Models are passed through at provider cost and transport fees are listed per provider.Is Vapi right for you?
Good for
- Startups or teams that need a managed voice agent platform with packaged support tiers, telephony integration, and documented per-minute transport and model billing elements for cost planning.
- Documents enterprise SLAs and high-availability claims useful for operational planning.
- Provides granular per-minute transport and model cost lines to estimate usage charges.
Keep in mind
- The Premier tier price is not posted and requires contacting sales for a quote.
- Some transport fees are charged by third-party providers, adding variable cost outside Vapi’s billing.
- Organizations that require a fully self-hosted open-source stack without vendor-managed services; Premier enterprise pricing and custom packages require sales engagement—confirm concurrency and transport costs for your minutes profile.
Pricing and plan limits
The pricing page shows explicit prices for Core and a $999 Pro reference and documents transport fees and add-on unit pricing. Premier requires contacting sales for a custom quote. The linked official pages list plan details and many per-minute transport/model line items.
