Overview

Layercode makes it easy for developers to build reliable, low-latency voice AI agents.

We provide the real‑time infrastructure required to turn any LLM or existing text-based agent into a reliable, conversational voice AI agent that speaks to users via the web, mobile, or phone.

Build reliable, low-latency voice agents that are ready for production
Our cloud platform offers everything you need to give your agent a voice: audio streaming, multilingual speech-to-text, text-to-speech in over 100 voices, and intelligent turn-taking, delivered through a simple webhook integration that works with the LLMs and agent libraries you already know and love.

Get started quickly, straight from the command line
Developers can get started with a single CLI command, connect any LLM, agent framework, or custom logic via a single webhook, and use our frontend SDKs or connect a phone number to let users speak to their agent.

Full control over your agent’s backend
Unlike WYSIWYG voice agent builders, Layercode gives developers complete control over their agent logic — without needing to wrestle with the complexity of a DIY solution: building, maintaining and managing every component of a real-time voice system.

Hot-swap leading voice model providers
By supporting different voice model providers, Layercode helps developers avoid vendor lock-in by retaining the ability to test, evaluate and swap the best voice models for their use case.

Track latency, record and replay voice sessions
Latency analytics and recordings let developers measure an agent’s latency, review any conversation and replay, review logs, or download the recording.

The first voice AI platform built for true global performance
Layercode’s cloud is powered by 330+ edge locations, helping ensure rock-solid performance and reliability for voice agents speaking to users anywhere on Earth.

True, usage-based pricing
True, usage-based pricing that only charges per-second when a user or agent is speaking — silence is always free.

By handling all of the complex, real-time audio infrastructure required to deliver reliable voice AI to production, Layercode lets developers focus on building their core application while delivering conversational voice AI experiences that feel human, scale with demand, avoid vendor lock-in, and remain affordable at scale.
