Layercode

What is Layercode?

Layercode is a cloud infrastructure platform that enables developers to build production-ready voice AI agents without managing the complexity of real-time audio systems. It handles the full voice pipeline — including speech-to-text, text-to-speech, turn-taking, and audio streaming — and connects to your own backend logic via a simple webhook. Developers retain complete control over their LLM, agent logic, and tool calls, while Layercode delivers the voice layer across a global edge network spanning 330+ locations for sub-50ms audio processing. It supports deployment across web, mobile, and phone channels, with usage-based pricing that only charges for active speaking time.

Key Features

• Managed Voice Pipeline

  Handles the full real-time audio stack — speech-to-text, text-to-speech, turn-taking, and low-latency audio streaming — so developers only need to focus on agent logic.

• Webhook-Based Backend Integration

  Connect any LLM, agent framework, or custom backend logic via a single webhook. No lock-in to a specific stack — deploy your backend anywhere.

• Global Edge Network

  Audio is processed at 330+ edge locations worldwide, delivering sub-50ms latency for voice agents serving users across any region.

• Multi-Provider Voice Model Support

  Supports leading STT and TTS providers including Deepgram, ElevenLabs, Cartesia, and Rime, with the ability to hot-swap providers without code changes.

• CLI & SDK Tooling

  A single CLI command scaffolds a full voice agent project with built-in tunneling, sample backends, and dashboard configuration. SDKs available for Node.js, Python, React, and Vanilla JS.

• Session Recording & Analytics

  Built-in latency analytics, session recording, conversation replay, and transcript export for debugging, QA, and performance monitoring.

Use Cases

• Voice AI Agent Development : Developers can rapidly prototype and ship production-grade voice agents for customer service, virtual assistants, or interactive applications.
• Telephony & Call Automation : Connect voice agents to phone numbers to automate inbound or outbound call workflows without building custom telephony infrastructure.
• Multilingual Voice Applications : Build voice interfaces that support users across languages and regions, leveraging edge deployment for consistent low-latency performance globally.
• LLM-Powered Conversational Products : Product teams can add a voice layer to existing text-based LLM agents or chatbots without rebuilding their core logic.
• Developer Tooling & Coding Assistants : Tools like Layercode's own Sled product demonstrate how voice interfaces can be added to coding agents for hands-free, mobile-accessible workflows.
