## How the top Ultravox alternatives compare

A closer look at the top 6: each Ultravox alternative's standing among Voice AI peers, its verdict record against Ultravox, and the trade-offs of leaving.

### 1. Bland AI

Among the 31 voice ai tools we track, Bland AI has the 12th-widest language coverage.
In our published verdicts, Bland AI beats Ultravox for no-code agency deploys, custom pipeline control, ecommerce support and orders, healthcare compliance, outbound sales campaigns and smb receptionist and booking.
The reverse angle matters too - Ultravox vs Bland AI: ~65% cheaper, about half the base concurrency.
Published pricing starts at $0.14 per minute, verified July 2026.

**Why teams switch (No-code agency deploys):** Bland AI offers a native no-code agent builder, while Ultravox does not (facts 2618ade6 vs 9049ca31). Neither tool supports white-label or sub-accounts (facts 53004a40 and 7bead963), so that dimension is a tie. For agencies that need non-developer deployment workflows, Bland AI's no-code builder is the decisive differentiator. [No-code agency deploys verdict](https://www.versusref.com/voice-ai/bland-vs-ultravox/)

Bland AI cost: ≈ $0.13 per minute all-in (est.), verified Jul 15, 2026.

### 2. ElevenLabs Agents

Among the 31 voice ai tools we track, ElevenLabs Agents has the 4th-widest language coverage and the 3rd-lowest latency - a fit for multilingual and localization projects and real-time, conversational apps.
Head-to-head, ElevenLabs Agents takes no-code agency deploys, custom pipeline control, ecommerce support and orders, healthcare compliance and smb receptionist and booking from Ultravox.
Before switching, weigh what stays behind - Ultravox vs ElevenLabs Agents: about half the languages, adds native sip trunking.
Its published rate is $0.05 per minute, verified July 2026.

**Why teams switch (No-code agency deploys):** For no-code agency deploys and white-label resale, ElevenLabs Agents has a no-code agent builder (fact b5a43883) while Ultravox explicitly lacks one (fact 9049ca31). Ultravox also has no white-label or sub-account support (fact 7bead963), a critical gap for agencies reselling to clients. ElevenLabs supports 70 languages vs Ultravox's 26 (fact 7340f19b vs 9b20a3df), broadening agency reach. These gaps make Ultravox unsuitable for this use case. [No-code agency deploys verdict](https://www.versusref.com/voice-ai/elevenlabs-agents-vs-ultravox/)

**Overall verdict:** ElevenLabs Agents is the stronger choice for teams needing a no-code builder, offering 70 languages versus 26 and a 75ms latency edge. Ultravox wins for developer-first teams requiring native SIP trunking, warm transfers, outbound campaigns, and barge-in handling, making its telephony stack more complete. Both share $0.05/min base pricing and $0/mo platform fees. ElevenLabs suits non-technical builders and multilingual deployments, while Ultravox suits engineering teams building telephony-heavy integrations.

ElevenLabs Agents cost: ≈ $0.05 per minute all-in (est.), verified Jul 15, 2026.

### 3. Retell AI

Among the 13 voice ai tools we track, Retell AI has the 5th-highest included concurrency - a fit for high-traffic deployments.
Head-to-head, Retell AI takes no-code agency deploys, custom pipeline control, ecommerce support and orders, healthcare compliance, outbound sales campaigns and smb receptionist and booking from Ultravox.
Before switching, weigh what stays behind - Ultravox vs Retell AI: about half the base concurrency, ~30% cheaper, no bring-your-own llm.
Its published rate is $0.07 per minute, verified July 2026.

**Why teams switch (No-code agency deploys):** For no-code agency deploys and white-label resale, Retell AI offers a dedicated no-code agent builder while Ultravox does not. Retell AI also provides partial white-label and sub-account support for agencies, while Ultravox offers none. Additionally, Retell AI includes a simulation and testing suite and broader native integrations including Go High Level and HubSpot, all critical for agency workflows. Ultravox lacks these features entirely. [No-code agency deploys verdict](https://www.versusref.com/voice-ai/retell-vs-ultravox/)

**Overall verdict:** Retell AI suits teams needing a full-featured platform: a no-code builder, testing suite, BYO LLM support, 20 concurrent calls at base tier, and richer integrations. Ultravox suits cost-sensitive or developer-first teams, with a base rate of $0.05/min versus Retell's $0.07/min, and a flat real cost of $0.055/min versus Retell's $0.085 to $0.415/min range. Neither option dominates overall; the right choice depends on whether budget or feature richness is the higher priority.

Retell AI cost: ≈ $0.25 per minute all-in (est.), verified Jul 15, 2026.

**Why teams switch (No-code agency deploys):** For a no-code agency needing white-label resale, Vapi offers a no-code agent builder while Ultravox explicitly lacks one. Vapi also provides partial white-label and sub-account support, whereas Ultravox has none. Additionally, Vapi provides a broader native integration set including GHL, Zapier, and Make, which are common agency tools, compared to Ultravox's telephony-only partner integrations. All three dimensions favor Vapi decisively for this use case. [No-code agency deploys verdict](https://www.versusref.com/voice-ai/ultravox-vs-vapi/)
