The Best Alternative to ElevenLabs in 2026: AI Voice Agents from $0.03/min

ElevenLabs makes excellent voices. But if you are running them in production, you have probably felt the three problems everyone runs into: unified credits that every product eats from, LLM and telephony billed on top of your agent minutes, and plan walls — you jump from $99 to $299 the moment you need more seats. This is the honest case for 008, the SaaS for AI voice agents as an alternative to ElevenLabs — and where each one wins.

What 008 actually is

008 Agent is the Grupo Astroline SaaS for building AI agents, voice and text. Its voice agents are built by and for the phone channel, on 25+ years of carrier heritage: they register as an extension of your existing phone system — exactly like a physical desk phone would. That single design decision changes the economics and the architecture of every voice use case you run on top.

The cost difference, in numbers

ElevenLabs conversational agents run at $0.08 per minute — before the LLM tokens and the telephony fees, which are billed separately. Voice quality is superb, but the final invoice is a function of three variables you don't control.

008's voices run on CPU with costs from from $0.03 per minute — voice and LLM included. You pay for minutes of conversation: the voice and the brain that drives it are one price. Only telephony rides separately, at your carrier's real rates. There is no credit pool, no model metering puzzle, and no surprise overage at the end of the month.

Why registering as an extension matters

• Your PBX treats the agent like any other endpoint: routing, recording, IVR and reporting keep working without re-cabling your telephony.

• No new trunk contracts or per-origin SIP fees — the agent sits inside the system you already pay for.

• Human handoff is native: transfer to a person is a transfer between extensions, not an integration project.

Privacy and control

Because the same company operates the voice network and the AI platform — the Grupo Astroline, a carrier with more than 25 years of trajectory — your call audio and transcripts don't cross a chain of third-party vendors. For regulated teams — healthcare, finance, government procurement — that's the difference between a compliance project and a deployment note.

Where ElevenLabs still wins

Fair is fair: for pre-produced narration, dubbing and cinematic voiceover, ElevenLabs' voice library is best in class. If your product is content, not conversations, it's a great tool. 008 is built for the other side of the market: live voice agents that talk to your customers.

The architecture difference: event-driven, not a pipeline

Most voice AI stacks chain services: transcribe, think, speak, repeat. Every hop adds latency and every hop bills you. 008 is event-driven: the agent reacts to telephony events the moment they happen — pickup, barge-in, DTMF, transfer — which is why it stays responsive on plain CPU hardware instead of needing a GPU farm to feel instant.

That same event core is what lets an agent register as an extension and behave like a first-class citizen of your phone system, not a bolted-on API.

Voice is the start, not the ceiling

The same agent that answers calls also runs on WhatsApp and other messaging channels — same brain, same guardrails, same knowledge base. With ElevenLabs you buy voice; conversations that continue on WhatsApp are a different product, a different bill. If your customers live in chat as much as on the phone, that difference compounds monthly.

Migrating off ElevenLabs without drama

• Export your scripts and conversation flows — your logic, your prompts. Nothing in 008 locks you in.

• Point your numbers at 008: the agents register as extensions of the PBX you already have.

• Pick voices — clone your brand voice or use the built-in library, both running on CPU from $0.03/min.

• Run the two stacks in parallel for a week; move traffic when you're convinced. No big-bang cutover.
