Alternatives
The right alternative depends on what you are replacing: price, AI quality, integrations, enterprise controls, or workflow focus. Start with the closest competitors, then use the related guides to narrow the decision.

Developer infrastructure for composing and operating real-time voice agents
Vapi lets teams combine speech recognition, models, voices, telephony, tools, and observability, but layered per-minute cost, retention, consent, reliability, and escalation must be proven with real calls.
A leading AI voice platform for text to speech, voice cloning, speech to text, dubbing, and conversational agents
ElevenLabs combines premium text to speech, voice cloning, multilingual audio generation, speech to text, developer APIs, and voice agents in one AI audio platform.
Dust is worth testing for teams that want employees to build and operate shared AI agents over company knowledge and tools while retaining model choice and administrative controls
Dust is worth testing for teams that want employees to build and operate shared AI agents over company knowledge and tools while retaining model choice and administrative controls. Its flexibility also creates the buying risk: every connector, agent instruction, tool permission, model, and credit-consuming action needs an owner. The relevant metric is accepted work per credit after review—not agents deployed.
Look for an alternative if Retell AI is too expensive, lacks the integrations you need, or is not strong enough for your primary workflow.
Compare output quality, setup time, pricing limits, supported models, API access, and whether the tool fits your team’s existing systems.
Shortlist two options, run the same real workflow through both, and keep the one that reduces rework rather than the one with the longest feature list.
