## How the top Hume EVI alternatives compare

The top 6 in depth: where each alternative ranks across the Voice AI field we track, which use cases it takes from Hume EVI, and what switching gives up.

### 1. Vapi

Among the 23 voice ai tools we track, Vapi has the 7th-cheapest per-minute rate - a fit for cost-sensitive, high-volume work.
Head-to-head, Vapi takes no-code agency deploys, custom pipeline control, ecommerce support and orders, outbound sales campaigns and smb receptionist and booking from Hume EVI.
Before switching, weigh what stays behind - Hume EVI vs Vapi: about half the latency, ~40% pricier, no native sip trunking.
Its published rate is $0.05 per minute, verified July 2026.

**Why teams switch (No-code agency deploys):** For a no-code agency building and reselling voice AI, two things matter most: a no-code builder and white-label or sub-account support. Both platforms offer a no-code agent builder, so that is a wash. On white-label and sub-account capability, Vapi offers partial support while Hume EVI publishes no white-label information at all, giving Vapi the edge on the single most agency-critical differentiator. Production cost also favors Vapi: its base rate of $0.05/min beats Hume EVI's $0.07/min, and Vapi passes LLM and TTS costs through at cost. Vapi also charges no monthly platform fee versus Hume EVI's $3/mo, and Vapi includes native outbound campaigns, a feature Hume EVI has no equivalent for. Agencies reselling at volume will find Vapi's lower per-minute rate and broader agency tooling meaningfully more competitive. [No-code agency deploys verdict](https://www.versusref.com/voice-ai/hume-evi-vs-vapi/)

**Overall verdict:** Vapi wins five of six use cases, and it dominates across buyer segments for clear reasons. Its base rate of $0.05/min undercuts Hume EVI's $0.07/min, and it carries no monthly platform fee versus Hume EVI's $3/mo charge, making it cheaper to start and scale. For no-code agencies, outbound sales, ecommerce, and SMB receptionists, Vapi's native integrations (GHL, Twilio, Zapier, Google Calendar), built-in outbound campaigns, warm transfer, DTMF/IVR, and SIP trunking cover the full telephony stack. Its $50M Series B signals production readiness. Hume EVI's lone win is healthcare, where its HIPAA BAA is included on the base plan rather than sold as a paid add-on. Vapi's 600 ms median latency trails Hume EVI's 300 ms, but breadth of features tips most buyers toward Vapi.

Vapi cost: ≈ $0.11 per minute all-in (est.), verified Jul 15, 2026.

### 2. OpenAI Realtime API

In our published verdicts, OpenAI Realtime API matches Hume EVI for ecommerce support and orders and outbound sales campaigns.
Before switching, weigh what stays behind - Hume EVI vs OpenAI Realtime API: adds bring-your-own llm.

**Overall verdict:** Hume EVI wins four of six use cases outright, with the remaining two as ties and OpenAI Realtime API winning none. The wins rest on concrete advantages. For healthcare compliance, Hume EVI includes a HIPAA BAA on its base plan, a critical credential that OpenAI Realtime API does not match. For no-code agency deploys, Hume EVI offers a built-in no-code agent builder, which OpenAI Realtime API lacks. For custom pipeline control, Hume EVI supports bring-your-own LLM and bring-your-own TTS voice, while OpenAI Realtime API supports neither. Pricing starts at $0.07/min plus a $3/mo platform fee, with 11 languages supported and 300 ms median latency making it competitive on performance. OpenAI Realtime API offers native SIP trunking, but that single advantage was not enough to flip any use case.
