Verdicts by use case

No-code agency deploys → ElevenLabs Agents

For no-code agency deploys and white-label resale, ElevenLabs Agents has a no-code agent builder while Ultravox explicitly lacks one. Ultravox also has no white-label or sub-account support, 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.

Custom pipeline control → ElevenLabs Agents

Both tools are API-first, but ElevenLabs Agents adds a no-code agent builder while Ultravox does not, giving engineering teams more flexibility to prototype alongside custom pipeline work. ElevenLabs also reports a 75 ms median e2e latency, which matters for real-time pipeline control. Ultravox lacks barge-in support and a testing suite, limiting pipeline iteration options. ElevenLabs also supports 70 languages vs Ultravox's 26, broadening pipeline applicability. The margin is narrow because Ultravox offers native SIP trunking and BYO TTS, which some engineering pipelines need.

Ecommerce support and orders → ElevenLabs Agents

For ecommerce support, multilingual reach is critical, and ElevenLabs covers 70 languages versus Ultravox's 26, reaching far more global customers. ElevenLabs also offers a no-code agent builder that simplifies order flow setup without engineering overhead, while Ultravox has no equivalent. Ultravox also lacks barge-in interruption handling, which weakens conversational feel during order interactions. ElevenLabs' 75 ms median latency supports natural dialogue. Both platforms share the same $0.05 per minute base price, so cost does not differentiate them.

Healthcare compliance → ElevenLabs Agents

For HIPAA-bound healthcare workflows, the critical requirement is a HIPAA BAA. ElevenLabs Agents offers a HIPAA BAA, though only on enterprise plans, meaning a defined compliance path exists. The available facts show no mention of Ultravox offering a HIPAA BAA at any tier. ElevenLabs Agents also supports 70 languages versus Ultravox's 26, and its 75 ms median latency suits real-time clinical interactions. The margin is narrow because the BAA requires an enterprise upgrade, but it remains a concrete compliance path that Ultravox facts simply do not provide.

Outbound sales campaigns → Ultravox

For outbound sales campaigns, Ultravox offers native outbound campaign support, warm transfer to human agents, a built-in knowledge base, native SIP trunking, and DTMF/IVR navigation. ElevenLabs Agents shows no comparable outbound campaign or warm transfer features in the facts. ElevenLabs does have advantages in latency at 75ms and language coverage at 70 languages versus 26 (fact 7340f19b vs 9b20a3df), but the direct outbound campaign tooling and human handoff capability in Ultravox are decisive for this use case.

SMB receptionist and booking → ElevenLabs Agents

For an SMB receptionist and booking use case, ease of setup and broad language support matter most. ElevenLabs Agents offers a no-code agent builder and supports 70 languages versus Ultravox's 26, which helps with diverse customer bases. Ultravox lacks a no-code builder and lacks barge-in interruption handling, which is critical for natural receptionist conversations. ElevenLabs also has a 75ms median latency supporting smooth interactions. Pricing is equal at $0.05/min on both sides, so the no-code setup advantage and broader language coverage tip this to ElevenLabs for a typical SMB.

Common questions

Do ElevenLabs Agents and Ultravox charge the same per minute rate?+

Both tools list a base price of $0.05 per minute with no monthly platform fee on standard plans, and neither requires an annual contract to access that rate.

How low is ElevenLabs Agents latency compared to Ultravox?+

ElevenLabs Agents claims a median end-to-end latency of 75 ms. No latency figure is available for Ultravox in the provided facts. Buyers prioritizing real-time responsiveness should request benchmark data directly from Ultravox before making a decision.

Can Ultravox handle caller interruptions mid-sentence?+

Neither Ultravox nor ElevenLabs Agents supports interruption handling (barge-in) according to available vendor-claimed data. If smooth barge-in handling is critical for your use case, verify the current support status directly with each vendor before committing to a platform.
