Voice AI Pricing Comparison: Vapi vs. Retell vs. ElevenLabs vs. Devaland


The Voice AI market has exploded in recent years. With so many platforms claiming to be "human-sounding" and "low latency," how do you choose the right one for your business? In this guide, we break down the four heavy hitters in the industry: Vapi, Retell, ElevenLabs, and our own managed ecosystem at Devaland.
The Players: Who are they for?
- βVapi: A developer-centric platform that offers high customization but requires significant technical skill to set up and maintain a stable RAG (Retrieval-Augmented Generation) system.
- βRetell AI: Similar to Vapi, but with a focus on ease of use for developers. Excellent latency, but still requires "hand-coding" your business logic.
- βElevenLabs: The gold standard for Voice Quality. However, ElevenLabs is primarily a TTS (Text-to-Speech) layer. To build an agent, you still need an LLM (like GPT-4) and an orchestration layer (like Vapi or Devaland).
- βDevaland Managed AI: We take the best-of-breed technologies (ElevenLabs for voice, custom RAG for intelligence) and provide a Fully Managed Service. You get the ROI without the dev-ops headache.
Pricing Comparison Table
| Feature | Vapi / Retell | ElevenLabs (TTS Only) | Devaland (Managed) |
|---|---|---|---|
| Base Cost | $0.15 - $0.30 / min | $0.05 - $0.15 / min | Monthly Subscription |
| Setup Fee | $0 (Self-serve) | $0 | Custom Implementation |
| Maintenance | Your Dev Team ($$$) | N/A | Included |
| RAG System | Manual Setup | N/A | Included & Optimized |
| Voice Quality | Variable | Industry Lead | Best-in-Class (using 11Labs) |
Why "Cheapest Per Minute" Is Often the Most Expensive
Platforms like Vapi and Retell look cheap at first glance. $0.15 per minute sounds great until you factor in the Developer Cost. To build a Voice AI agent that doesn't hallucinate and actually helps customers, you need:
- βA prompt engineer.
- βA RAG architect to feed your business data.
- βA monitoring system to catch failed calls.
If your team spends 40 hours a month fixing the AI, your "cheap" minute just became very expensive.
The ElevenLabs Factor: Why Voice Quality Matters
Today, customers can smell a robot from a mile away. If your Voice AI sounds like a GPS from 2010, they will hang up. ElevenLabs has solved this by using "Emotional Latency" modeling. This allows the AI to stutter naturally, take breaths, and respond with empathy.
At Devaland, we use ElevenLabs as our default voice engine because it correlates directly with higher Resolution Rates.
ROI Analysis: The Devaland Difference
When we implement a Voice AI system, we don't just "plug it in." We architect it for ROI.
- βMedical Practices: We focus on CRM/EMR integration to reduce no-shows.
- βE-commerce: We focus on real-time inventory tracking and order status.
- βRestaurants: We focus on high-speed order taking and upselling.
Summary: Which One Should You Choose?
- βChoose Vapi/Retell if you have a staff of 3+ developers and want to build a proprietary tool from scratch.
- βChoose ElevenLabs if you are an app developer looking only for a TTS API.
- βChoose Devaland if you are a business owner who wants a Result (higher sales, lower costs, better support) without needing to hire a software team.
