Unpod vs LiveKit vs Pipecat

TL;DR

	Unpod	LiveKit	Pipecat
What it is	Communication infra for AI agents	Real-time audio infrastructure + agent framework	Open-source voice pipeline framework
You own	Your agent logic	Everything	Everything
They manage	Phone numbers, STT/TTS, VAD, orchestration	WebRTC rooms (self-hosted or cloud)	Nothing - it’s a library
Phone numbers	Built-in, no carrier account	Bring your own SIP trunk	Bring your own
STT/TTS	Fully managed, automatic failover	You configure and run providers	You configure and run providers
Time to first call	~2 hours	~4 months	~4 months
Scaling	Automatic	You manage workers	You manage processes
Your agent format	Webhook, SDK, LangChain, MCP	LangChain, custom	LangChain, custom
Best for	Teams that want calling infra handled	Teams needing full audio control	Teams wanting pipeline flexibility

The Core Difference

LiveKit and Pipecat are audio frameworks. They give you building blocks to construct a voice pipeline. You choose and wire every component - STT provider, TTS provider, VAD, transport, endpointing. Then you deploy it, scale it, and keep it running. Unpod is calling infrastructure. You bring the agent. We give it a phone number and handle all the audio plumbing.

Pipecat

Pipecat gives you components to build a voice pipeline yourself:

# Pipecat - you wire and run every component
pipeline = Pipeline([
    transport.input(),
    stt,
    llm,
    tts,
    transport.output(),
])
runner = PipelineRunner()
await runner.run(PipelineTask(pipeline))

You pick the STT, the TTS, the transport. You manage the process. You handle failover. Maximum flexibility - maximum setup work. Good fit: Teams with specific provider requirements or non-standard pipeline shapes. Research and experimental systems.

LiveKit

LiveKit provides real-time infrastructure (WebRTC rooms, SIP, TURN) and an agent framework on top:

# LiveKit - you configure all providers and manage the room
async def entrypoint(ctx: JobContext):
    await ctx.connect()
    agent = VoiceAgent(
        vad=silero.VAD.load(),
        stt=deepgram.STT(),
        llm=openai.LLM(),
        tts=cartesia.TTS(),
    )
    agent.start(ctx.room)

You configure every provider. You deploy and manage the LiveKit server (or pay for LiveKit Cloud). Phone numbers require a SIP trunk from a carrier. Good fit: Teams already on LiveKit, or needing fine-grained WebRTC control for browser and mobile use cases beyond phone calls.

Unpod

You bring the agent. Unpod gives it a phone number and handles every audio layer:

# Unpod - you write the logic, we handle the communication stack
async def handle_call(ctx: CallContext) -> None:
    ctx.session.dialog_machine = DialogMachine(flow=flow, llm="anthropic/claude-haiku-4-5")
    await ctx.session.run()

AgentRunner(entrypoint=handle_call, agent_id="agt_...").start()

Numbers provisioned from Unpod. STT/TTS configured via voice profiles with automatic failover. Orchestration and dispatch handled automatically. You can also point Unpod at an existing HTTP endpoint or LangChain agent without writing any SDK code. Good fit: Teams that want production voice calls without becoming telephony experts.

When to Choose Each

Choose Unpod when:

You want phone numbers without a carrier account or SIP trunk
You have an existing agent and want to give it voice in hours - not months
You do not want to manage STT/TTS provider accounts, failover, or audio infrastructure
You want Voice + SMS + WhatsApp from one API
Your core value is the agent logic - not the communication stack

Choose LiveKit when:

You need granular WebRTC control (custom ICE, codec requirements)
You are already running LiveKit infrastructure
You need browser or mobile real-time communication beyond phone calls
You want full ownership of every infrastructure component

Choose Pipecat when:

You need a highly customised pipeline shape or experimental architecture
You want maximum control over every processing step
You are comfortable managing deployment, scaling, and provider accounts yourself
