LanguageProject Introduction
Summary
LiveKit provides a complete, open source infrastructure for building real-time audio and video applications. It includes a high-performance Go server implementing an SFU and client SDKs for major platforms, enabling developers to quickly integrate features like video conferencing, live streaming, and interactive communication into their applications.
Problem Solved
Building and scaling real-time communication applications using raw WebRTC is notoriously complex, requiring deep expertise in media servers, networking, and client-side implementation across platforms. LiveKit abstracts away this complexity, providing a ready-to-use server and intuitive SDKs.
Core Features
Multi-Platform SDKs
Build real-time applications across web, mobile (iOS, Android), and desktop using idiomatic SDKs for various platforms like React, Flutter, React Native, Swift, Kotlin, and standard JS.
Scalable SFU Architecture
Leverage a high-performance Selective Forwarding Unit (SFU) architecture designed for scalability, supporting large rooms and concurrent sessions.
All-in-One Server
Integrated signaling, room management, and optional TURN server capabilities simplify deployment and connectivity.
Server-Side Recording & Streaming
Easily add server-side recording and streaming capabilities to capture and broadcast live sessions.
