The Flat-Rate Alternative to Vapi
Vapi charges $0.05/min on top of third-party ASR, LLM, and TTS fees - adding up to $0.13–$0.33 per minute in real-world usage. Voquii is $497/mo flat for unlimited inbound minutes on proprietary GPU infrastructure. No per-minute billing. No third-party API dependency. 2x faster latency.
Where Vapi Falls Short for Agencies
Per-Minute Pricing Adds Up Fast
Vapi advertises $0.05/min, but that's just their orchestration fee. You still pay separately for Deepgram (ASR), OpenAI or Claude (LLM), ElevenLabs (TTS), and Twilio (telephony). Real-world costs land at $0.13–$0.33 per minute. For 10 active clients, that's ~$1,800/mo in usage fees alone - and it scales linearly with every minute your AI handles.
API Wrapper Architecture Means Higher Latency
Vapi orchestrates calls between Deepgram, OpenAI, and ElevenLabs. Each API hop adds network latency. Their typical TTFA is ~800ms (465ms with aggressive optimization). Every millisecond of delay makes the AI sound less natural and increases caller drop-off.
No Native White-Label for Agencies
Vapi doesn't include white-label tools. To deploy under your brand, you need a third-party wrapper like Vapify or VoiceAIWrapper - adding another vendor, another bill, and another point of failure. There's no built-in agency dashboard, no sub-account management, no custom domain support.
Unpredictable Bills
With 4+ providers each billing per minute, your monthly cost depends on call volume, LLM model choice, and TTS provider. Users frequently report "hidden costs" and bills significantly higher than expected. For agencies billing clients, this unpredictability destroys margins.

What Vapi Does Well
An honest comparison means acknowledging strengths on both sides.
Multi-Provider Flexibility
Vapi lets you mix and match ASR, LLM, and TTS providers. If you need a specific provider like ElevenLabs voices or GPT-4 specifically, Vapi gives you that flexibility. Voquii runs a self-hosted stack - you get our optimized pipeline, not a choice of third-party vendors.
Outbound Calling
Vapi supports both inbound and outbound calling. Voquii is inbound-only by design - a deliberate safe harbor strategy that eliminates TCPA risk, spam flags, and carrier reputation damage.
Developer-First API
Vapi has a rich API with thousands of configuration options, SDKs, and a CLI. It's built for developers who want granular control. Voquii is built for agencies who want a turnkey platform for multi-client management.
Multi-Agent Squads
Vapi offers "Squads" - multi-agent orchestration with context-preserving transfers between specialized agents. Voquii uses a single-agent model with function calling and handoff-to-human routing.
Why Agencies Switch from Vapi to Voquii
Predictable Margins
Your cost is $497/mo no matter how many minutes your clients use. Charge $199–$399/mo per client, and every new client is pure margin. With Vapi, your costs scale with usage - which means your margins shrink as clients use more.
2x Faster Voice Response
375ms Time-to-First-Audio vs Vapi's ~800ms. Every component of our pipeline runs on co-located bare-metal GPUs with zero external API hops. Callers get a more natural conversation experience.
Built-In White Label
Custom domain with auto-SSL, your logo, your brand colors, custom SMTP, and a full agency portal with sub-account management. No third-party wrapper needed. Your clients never see Voquii.
Zero Third-Party Dependencies
Vapi requires you to manage API keys for Deepgram, OpenAI, ElevenLabs, and Twilio - each with their own billing, rate limits, and potential outages. Voquii runs the entire ASR → LLM → TTS stack on proprietary hardware.
No Usage Surprises
Vapi users report "hidden costs" and bills significantly higher than the advertised $0.05/min. With Voquii, what you see is what you pay: $497/mo. Period.
One-Click Migration from Vapi
Voquii has a built-in importer that connects directly to the Vapi API. Paste your API key, click import, and your assistants, phone numbers, and call history are in Voquii in minutes. No CSV exports, no manual re-entry.
