Enterprise Voice AI, Without
the Multi-Vendor Bill
Vapi AI is an orchestration layer built for developers who want to assemble their own voice
stack from separate STT, LLM, TTS, and telephony providers. Zudu AI is built for enterprises that need
production-ready voice agents in 48 hours — with sub-500ms response, 80+ languages, one all-inclusive per-minute rate,
and full HIPAA, GDPR, and SOC 2 compliance included.
Three reasons teams move from Vapi AI to Zudu
One bill instead of five, production-ready in 48 hours instead of weeks, and enterprise compliance included instead of a $1,000/month add-on.
Predictable costs from day one
Vapi AI's $0.05/min platform fee is just the orchestration layer. In production, you pay separately for your LLM, TTS, STT, and telephony provider — real-world costs land between $0.15–$0.33/min across 4–6 vendor invoices. Zudu AI offers transparent, all-inclusive pricing from $0.08/min — one rate, one invoice, no component stacking.
Production-ready in 48 hours, not weeks
Vapi AI is an orchestration layer — you bring your own STT, LLM, TTS, and telephony providers, then wire them together via APIs and webhooks. Most production deployments take weeks of engineering. Zudu AI's no-code builder lets Ops, CX, and Product teams deploy production agents in 48 hours without managing a single external provider.
Compliance included, not a $1,000/mo add-on
Vapi AI charges a $1,000/month add-on for HIPAA compliance on pay-as-you-go plans. SOC 2 and HIPAA are available on enterprise tiers but require custom negotiation. Zudu AI includes HIPAA, GDPR, and SOC 2 Type II compliance on all plans — no add-on fees, no enterprise-only gating.
Zudu AI vs Vapi AI — feature by feature
Side-by-side on the capabilities enterprise teams evaluate during vendor selection. Sources linked in the methodology note below.
| Capability | Zudu AI | Vapi AI |
|---|---|---|
| Average response latency | < 500ms | ~800ms typical (500–800ms range depending on stack) |
| Languages supported | 80+ out of the box | 100+ via third-party providers (config required) |
| Deployment model | No-code builder + API | API-first orchestration layer (Flow Studio for prototyping) |
| Time to first production agent | 48 hours | Weeks (multi-provider integration + engineering) |
| HIPAA compliance | Yes — included on all plans | $1,000/mo add-on (pay-as-you-go); included on enterprise |
| SOC 2 Type II | Yes — included | Enterprise plan only |
| GDPR compliance | Yes | Infrastructure provided; config is customer's responsibility |
| Built-in analytics & reporting | Yes — native dashboard | Basic call logs (14-day retention); advanced analytics require external tools |
| Inbound + outbound | Both, unified workflows | Both supported |
| Pricing model | Transparent, from $0.08/min (all-inclusive) | $0.05/min platform fee + LLM + TTS + STT + telephony ($0.15–$0.33/min in production) |
| Number of vendor invoices | 1 | 4–6 (Vapi + LLM + TTS + STT + telephony + add-ons) |
| Concurrency | Included in enterprise tiers | 10 free; $10/month per additional concurrent line |
| HIPAA add-on cost | $0 | $1,000/month on pay-as-you-go |
| Surge pricing | None | +$0.05/min during traffic surges |
| Data retention | Configurable | 14-day call history / 30-day chat (standard); custom on enterprise |
| Voice cloning | Included | Via third-party providers (e.g. ElevenLabs); billed separately |
| Target user | Enterprise Ops, CX, Product | Developers and engineering-heavy orgs |

Move from Vapi AI to Zudu in under a week
Average migration time is 5 to 7 days. A dedicated migration manager is included at no additional cost. Keep your existing phone numbers, integrations, and call logs intact.
Assessment
Share your current Vapi AI agents, provider stack, and call volume. Our migration team maps every workflow to Zudu's no-code builder and flags improvements along the way.
Rebuild & Integrate
We rebuild your agents in Zudu, connect your existing integrations (Twilio, Vonage, CRMs, Zapier, custom APIs), and keep your phone numbers exactly as they are. Zero changes to downstream systems.
Parallel Run & Go-Live
Run Zudu and Vapi in parallel, compare call quality and conversion side by side, then cut over with zero downtime. You keep full control over the switch.
Average migration time from Vapi AI, including parallel-run period. Migration manager, integration reconnection, agent rebuild and workflow mapping included at no extra cost.
Start migrationWhat you get on Zudu that Vapi doesn't ship
Four capabilities included by default on Zudu that require custom integration, add-on fees, or multi-vendor management on Vapi AI.
Native no-code agent builder
Build, test and deploy voice agents visually. Ops and CX teams own the flow — no engineering tickets, no webhook debugging, no multi-provider wiring. APIs available when you want them.
On Vapi: Flow Studio for basic prototyping; production agents require API/SDK development and manual provider integration.
All-inclusive pricing, one invoice
One per-minute rate covers voice, LLM, STT, TTS, telephony, analytics, and compliance. No component stacking, no surge pricing, no concurrency surcharges, no separate vendor accounts.
On Vapi: $0.05/min platform fee covers orchestration only; LLM ($0.02–$0.20/min), TTS ($0.04–$0.08/min), STT (~$0.01/min), and telephony (~$0.015/min) billed separately — resulting in 4–6 vendor invoices.
Enterprise compliance, included
HIPAA, GDPR, and SOC 2 Type II out of the box on all plans. Full call recording, AES-256 encryption, access controls, and audit trails — no add-on fees, no enterprise-only gating.
On Vapi: HIPAA compliance is a $1,000/month add-on on pay-as-you-go; SOC 2 is enterprise-only; GDPR compliance configuration is the customer's responsibility.
Built-in analytics & speech insights
Live dashboards for call volume, sentiment, intent distribution, drop-off points and per-agent performance — no external logging stack or BI pipeline required.
On Vapi: Basic call logs with 14-day retention on standard plans; advanced analytics require external platforms (Grafana, Datadog).
When Vapi AI is the better choice
We maintain this page to help you make a decision, not just to win one. There are real cases where Vapi AI is a genuinely better fit, and pretending otherwise wastes your time and ours.
You have a strong in-house engineering team
Vapi is API-first and gives developers full control over every component of their voice stack. If your team wants to choose their own LLM, STT, and TTS providers and code every call flow, Vapi's open orchestration model is a strong fit.
You already have negotiated vendor contracts
If you have existing agreements with a specific LLM, TTS, or STT provider at discounted rates, Vapi's bring-your-own-provider model lets you preserve those contracts and route through your preferred stack.
You need 100+ language support via specific providers
Vapi supports 100+ languages through third-party STT/TTS providers. If you need a specific regional language only available through a particular vendor, Vapi's open provider model gives you that flexibility — at the cost of separate billing and configuration.
You're a developer building a prototype without HIPAA needs
Vapi's pay-as-you-go entry point is accessible for early-stage testing. If you don't need HIPAA compliance and have an engineering team comfortable with API integration, it's a reasonable starting point.
One rate vs. a five-layer stack
Vapi AI's $0.05/min advertised rate covers only the orchestration layer. Most production deployments cost $0.15–$0.33/min once LLM, TTS, STT, telephony, and compliance add-ons are stacked.

From five vendor invoices to one — in three days
"We were managing five different vendor invoices and spending more time debugging provider integrations than improving our voice workflows. Zudu's all-inclusive model and no-code builder gave us one bill and a three-day launch. Our Ops team hasn't opened an engineering ticket since."
