Closest alternatives to TelEcho

The ones people open most here come first, then the closest matches. How we check

1
ElevenLabs Agents
From Free
Hosted platform for building voice and chat agents, with telephony, SDKs and a choice of LLM.
Why it's on this list
Claude: YesAnthropic models are natively selectable in agent settings; a few older Claude models drop out in EU data-residency workspaces.
Source ↗
Better than TelEcho at
- Open models: Yes ↗
- Model choice: Yes ↗
Trade-offs
None found.
Watch for
Covers the voice + LLM-orchestration layer, not a turnkey ops product, CRM/helpdesk workflows, observability and compliance UI are yours to build.
2
Retell AI
From $0.07 per minute
Pay-as-you-go platform for building, testing and running AI phone, chat and SMS agents.
Why it's on this list
Claude: YesAnthropic models are first-class choices on the pay-as-you-go plan, each with its own published per-minute voice rate and per-message chat rate, from Claude Haiku tiers up to Opus; one Sonnet tier is even flagged as a recommended default.
Source ↗
Better than TelEcho at
- Open models: Partly ↗
- Model choice: Yes ↗
Trade-offs
- Agent permissions: Partly ↗
Watch for
True per-minute cost is the sum of stacked components, so budgeting requires modelling model, voice, and telephony together.
3
Bland
From Free
Enterprise voice AI platform for inbound and outbound phone agents, running on Bland's own self-hosted models.
Why it's on this list
Free tier: YesYou can sign up and build without a sales call or a card, though call minutes are billed once the two credits are gone.
Source ↗
Better than TelEcho at
- API access: Yes ↗
Trade-offs
- Agent permissions: Partly ↗
- Claude: No ↗
Watch for
Voice cloning across the full 40+ language set and the lowest per-minute rates are effectively Enterprise-tier features.

The rest of the shortlist

LiveKit Agents
Open-source Python and Node.js framework for voice AI agents, with LiveKit Cloud hosting, telephony and observability.
Watch for: A framework, not a no-code or dashboard-first builder. Expect to write and deploy real code, unlike this category's more configured rivals.
From Free
Vapi
Developer platform for building, testing and deploying voice AI agents that make and receive phone calls.
Watch for: True per-minute cost is the sum of several passed-through services, so the headline platform fee understates spend.
From $0.05 per minute
OpenAI Realtime API
Speech-to-speech voice agent API with tools, interruptions and WebRTC, WebSocket or SIP transports.
Watch for: 60-minute maximum session duration.
From $10 per 1m input tokens
Cartesia
Real-time speech models and a managed runtime for production phone and web voice agents.
Watch for: Line's voice-agent runtime cannot be self-hosted — only the underlying Sonic/Ink models can, on an Enterprise contract.
From Free
Deepgram Voice Agent API
One WebSocket API that runs speech-to-text, LLM orchestration and text-to-speech for real-time voice agents.
Watch for: No dedicated free tier. A one-time $200 credit only, then usage billing from the first paid session.
From $0.05 per minute
Telnyx Voice AI AgentsVerified owner
Carrier-owned platform for phone and web voice agents, with telephony, STT, TTS, LLM and orchestration in one stack.
From $0.05 per minute
