Is Wixzel Phone an alternative to LiveKit Agents?

They sit at different layers, so it is a build-or-buy choice rather than a swap. LiveKit Agents is a framework you write against and operate; Wixzel Phone is a hosted API where the orchestration already runs. If you want to own the conversation loop, use the framework. If you want a call placed by an HTTP request, use the API.

Which is cheaper, LiveKit Agents or Wixzel Phone?

The framework is free, so on paper it always wins; the honest comparison includes the infrastructure you run, the provider accounts you hold and the engineering time to build and operate it. Wixzel Phone's engines are $0.0466 to $0.1851 per connected minute including the orchestration fee, with telephony at your carrier's rate and no provider bills. Price the total, not the licence.

Can I bring my own SIP trunk to both?

Yes. LiveKit SIP accepts trunks you configure yourself, and Wixzel Phone requires one: it sells no numbers and no minutes, and puts no markup on carrier rates. Wixzel Phone also runs agents in your web and mobile apps over a WebSocket with no trunk at all.

Do I need provider keys for Wixzel Phone the way I do for LiveKit Agents?

No. LiveKit Agents expects you to hold a key for each provider you wire in. Wixzel Phone's provider accounts are platform-owned and one prepaid balance covers every engine, which is a deliberate trade: less choice of provider, nothing to reconcile.

What happens to my agents if Wixzel Phone goes away?

A fair question to ask of an alpha run by a sole proprietor, and the strongest argument for the framework. Agents are a prompt, a voice and an engine name, and the API is documented by an OpenAPI spec, so the definitions port; the running service does not. If that risk is unacceptable, LiveKit Agents is the safer choice and this page says so.

Comparison

Wixzel Phone vs building on LiveKit Agents

This is the build-or-buy comparison rather than a like-for-like one. LiveKit Agents is a framework you write against and operate; Wixzel Phone is an HTTP API where the orchestration already runs. The real question is whether you want to own the agent runtime.

Last updated 12 September 2026

Written by the operator of Wixzel Phone, so read it as the interested party it is. LiveKit Agents is described from its own public documentation at the level of business model, not rate, and every section names where it is the better choice.

LiveKit Agents is for

teams who want to own the conversation loop in their own code, already run infrastructure or need to self-host, and are willing to operate a worker fleet and hold provider accounts to get that control.

Wixzel Phone is for

developers who want a call placed by an HTTP request, one prepaid balance instead of five provider invoices, and no runtime of their own to scale or page on.

What LiveKit Agents is

LiveKit Agents is an open-source framework for building realtime voice agents on top of LiveKit's WebRTC infrastructure, with SIP support for phone calls and a hosted cloud option for the infrastructure underneath.

Side by side

Attribute	LiveKit Agents	Wixzel Phone
What you integrate	A framework. You write the agent in Python or Node, run it as a worker process, and deploy and scale that fleet yourself unless you buy the cloud offering.	An API. POST /v1/agents to define one, POST /v1/calls to place a call. Nothing of yours runs during the call.
Telephony	LiveKit SIP accepts inbound and outbound trunks you configure; the cloud offering also sells connectivity.	Bring your own SIP trunk for phone calls: no numbers or minutes sold, no markup on carrier rates. Agents also run in your web and mobile apps over a WebSocket, with no trunk.
Provider accounts	You bring and pay for every key: transcription, model and voice, each billed and rate-limited separately.	Platform-owned. No Deepgram, ElevenLabs, OpenRouter, Sarvam or Google keys to bring.
Billing model	The framework is open source and free. You pay each provider directly, plus infrastructure — your own, or LiveKit Cloud for the WebRTC and SIP layer.	Prepaid credit spent per second, per token and per character, plus a flat orchestration fee; $0.0466 to $0.1851 per connected minute at typical speech rates. Every charge itemised.
Voice engines	Any provider with a plugin, wired together in your own code, with the turn-taking and interruption logic exposed to you.	4 presets (classic, sarvam, gemini-live, deepgram-agent) or compose your own from named provider/model pairs.
Beyond the call	Out of scope by design. Campaigns, leads, appointments and knowledge bases are yours to build and store.	First-class API resources: campaigns, leads with bulk import, appointments, knowledge bases, and a webhook with a delivery log.
SDKs	Mature SDKs across server and client languages, including browser and native mobile, from the wider LiveKit project.	An official TypeScript SDK (npm: wixzel-phone) for TypeScript, JavaScript and edge runtimes, and an official Dart SDK (pub.dev: wixzel_phone) for Dart and Flutter, each with a realtime client for talking to an agent from a browser or app. Other languages use plain HTTP and JSON with an OpenAPI document. An official MCP server covers AI agents.
No-code builder	No. It is a code framework.	No. Agents are created with POST /v1/agents; the console is for keys, billing and logs.
Maturity	Widely adopted, venture-backed, large community, used in production at scale.	Alpha, deployed, operated by a sole proprietor in India.
Where it runs	Anywhere you deploy it, or LiveKit Cloud's global edge. Self-hosting makes data residency your decision.	Hetzner, Helsinki (EU); providers in the US and India process audio during a call.

LiveKit Agents is open source and free to run; there is no platform fee to compare. The costs are the infrastructure you deploy it on (your own, or LiveKit Cloud) and the transcription, model and voice accounts you hold directly. Check those pricing pages for current figures. Wixzel Phone's figures are generated from the price book the meter bills against.

Where LiveKit Agents is better

Control. The turn-taking, interruption handling and tool-calling loop is your code, so behaviour Wixzel Phone does not expose as a setting is a patch away rather than a feature request.
Self-hosting. If audio may not leave your infrastructure, or a regulator needs to see where it runs, an open-source framework answers that and a hosted alpha does not.
Scale and track record. LiveKit runs realtime media in production for large deployments; Wixzel Phone has never been load-tested above single-digit concurrency.
Ecosystem. Far more provider plugins, client SDKs and community answers, and no dependency on one operator continuing to run a service.
No lock-in. The framework is Apache-licensed and the provider accounts are yours, so leaving costs you a deployment rather than a migration.

Where Wixzel Phone is better

Nothing of yours runs during a call. There is no worker fleet to size, autoscale, patch or be paged about, which is the cost people underestimate when they choose a framework.
One balance instead of five invoices. No Deepgram, ElevenLabs, OpenRouter, Sarvam or Google account to open, fund, rate-limit or reconcile.
The application layer is already there. Campaigns, leads, appointments, knowledge bases and webhook delivery logs are endpoints, not a backlog.
An MCP server, so an AI agent can place and inspect calls without you writing an integration.
Indian languages end to end with the sarvam engine, priced from the same book as everything else.
Per-second itemisation across every component in one ledger, rather than reassembling a call's cost from separate provider bills.

Stay with LiveKit Agents if

You need to own the conversation loop, or you have already written one.
Compliance requires self-hosting or a specific data residency.
You run infrastructure already, and a worker fleet is marginal cost rather than a new discipline.
You need proven scale, or a vendor whose disappearance would not end the product.

Try Wixzel Phone if

Operating the runtime is the part you do not want, and the agent itself is a prompt and a voice.
Provider key sprawl and five invoices a month are the actual cost, not the per-minute rate.
You would otherwise build campaigns, leads, appointments or a knowledge base yourself.
You are building for Indian languages and want them priced from the same book as everything else.
