Introduction

MikroRoom is an ultralight video meeting tool built with WebRTC.

What is MikroRoom?

MikroRoom is a self-hosted video conferencing solution that prioritizes simplicity and performance. Built with vanilla TypeScript and Node.js, it provides everything you need for video meetings without the overhead of heavy frameworks. This allows MikroRoom to run with incredibly modest hardware and becomes a cost- and performance-efficient way to do fully private (and sovereign!) video conferencing.

Key Features

Zero Dependencies: Pure Node.js + TypeScript with no runtime dependencies
Modern Vanilla Stack: No React or other frameworks, just HTML/CSS and TS that compiles to JS
Super fast loads: ~25KB transfer size for the client app means it works on any connection
Modern UX: Looks and behaves like you’d expect of a modern app
WebRTC: Native Peer-to-peer video/audio with efficient signaling
Self-Hosted: Full control over your data and infrastructure
Production-Ready: Built-in security, rate limiting, etc.

Perfect For

Small teams (< 8 participants)
Privacy-conscious organizations
Self-hosted environments
Developers who want control
Learning WebRTC fundamentals

Architecture Overview

MikroRoom consists of two main components:

Backend: Node.js HTTP server with WebSocket signaling
Frontend: TypeScript compiled with esbuild to vanilla JS (ESM)

The backend handles signaling and room management, while actual media (video/audio) flows directly between participants via WebRTC, ensuring low latency and privacy.

Get Started

Get a meeting room running in just a few commands:

curl -sSL https://releases.mikroroom.com/install.sh | bash

# Install MikroRoom
mikroroom install

# Initialize in your project directory
mkdir my-meeting && cd my-meeting
mikroroom init

# Start the server
mikroroom start

# In a second terminal, run the frontend app
npx http-server app -p 8000

Then open http://localhost:8000 in your browser!
