​
Overview

Livekit is a powerful, open-source WebRTC server and client SDK that enables real-time audio communication. It’s designed for applications that require robust, scalable real-time features.

​
Key Features

  • Scalable architecture
  • Extensive documentation and community support
  • SDKs for various languages and platforms (web, mobile, desktop)

​
Getting Started

​
Prerequisites

Make sure you have navigated to the software directory before proceeding.

​
Installing Livekit

Before setting up the environment, you need to install Livekit. Follow the instructions for your operating system:

​
Environment Setup

  1. Create a .env file in the /software directory with the following content:
ELEVEN_API_KEY=your_eleven_labs_api_key
DEEPGRAM_API_KEY=your_deepgram_api_key
NGROK_AUTHTOKEN=your_ngrok_auth_token
ANTHROPIC_API_KEY=your_anthropic_api_key

Replace the placeholders with your actual API keys.

Eleven Labs

Get your Eleven Labs API key for text-to-speech

Deepgram

Obtain your Deepgram API key for speech recognition

Ngrok

Sign up for Ngrok and get your auth token

​
Starting the Server

To start the Livekit server, run the following command:

poetry run 01 --server livekit

To generate a QR code for scanning

poetry run 01 --server livekit --qr

To expose over the internet via ngrok

poetry run 01 --server livekit --expose

In order to use the mobile app over the web, use both flags

poetry run 01 --server livekit --qr --expose

Currently, our Livekit server only works with Deepgram and Eleven Labs. We are working to introduce all-local functionality as soon as possible. By setting your profile (see Configure Your Profile), you can still change your LLM to be a local LLM, but the interpreter.tts value will be ignored for the Livekit server.

​
Livekit vs. Light Server

  • Livekit Server: Designed for devices with higher processing power, such as phones, web browsers, and more capable hardware. It offers a full range of features and robust performance.

  • Light Server: We have another lightweight server called the Light server, specifically designed for ESP32 devices. It’s optimized for low-power, constrained environments.

​
SDK Integration

Livekit provides SDKs for various programming languages and platforms, allowing you to easily integrate real-time communication features into your applications.

​
Available SDKs

  • JavaScript/TypeScript
  • React
  • React Native
  • iOS (Swift)
  • Android (Kotlin)
  • Flutter
  • Unity
