LiveKit Has a Free Open-Source WebRTC Platform

Twilio charges per minute. Daily.co has usage limits. LiveKit is open-source, self-hostable, and handles everything from video calls to live streaming.

What LiveKit Does

LiveKit is a real-time communication platform built on WebRTC:

Video and audio rooms — up to thousands of participants
Screen sharing — with audio capture
Recording and streaming — to S3, RTMP, or HLS
AI integration — process audio/video with AI agents
Client SDKs — JavaScript, React, Swift, Kotlin, Flutter, Unity
SFU architecture — Selective Forwarding Unit for scalability

Quick Start

# Self-host with Docker
docker run --rm -p 7880:7880 -p 7881:7881 \
  -e LIVEKIT_KEYS="devkey: secret" \
  livekit/livekit-server

# Or use LiveKit Cloud (free tier available)
# Generate a token
livekit-cli create-token --api-key devkey --api-secret secret \
  --join --room my-room --identity user1

React Integration

import { LiveKitRoom, VideoConference } from "@livekit/components-react";

function VideoCall() {
  return (
    <LiveKitRoom
      serverUrl="wss://your-livekit-server"
      token={token}
    >
      <VideoConference />
    </LiveKitRoom>
  );
}

Free Tier (Cloud)

Resource	Free
Participant minutes	5,000/month
Recording	100 min/month
Egress	1 GB

Self-hosted: completely free, no limits.

Why LiveKit Over Alternatives

Open source — MIT license, self-host without limits
AI-ready — built-in AI agent framework for voice/video AI
Performance — Go-based SFU handles 1000s of streams
Full stack — recording, streaming, egress included
Modern SDKs — React components, not raw WebRTC APIs

Use Cases

Telehealth — HIPAA-compliant with self-hosting
EdTech — virtual classrooms with screen share
AI assistants — real-time voice AI with Agents framework
Live streaming — to YouTube/Twitch via RTMP egress

Building video/audio features? I help teams implement real-time communication with LiveKit — from architecture to deployment.
