# I built a real-time multiplayer 3D IDE with WebRTC voice chat and AI generation from scratch 🚀 > Source: > Published: 2026-06-19 03:01:56+00:00 Hi DEV community! 👋 I want to share a project I've been working on: **IA Code Studio** ([https://ia-codestudio.com](https://ia-codestudio.com)). It is a next-generation interactive WebGL playground and IDE designed to make building Three.js scenes, 3D widgets, and interactive websites as fast and collaborative as possible. ## Here is the backstory of how it was built, the architecture behind it, and the features we packed into it. ## 🌟 The Core Features ### 🤖 1. AI Prompt-to-3D Co-pilot Writing boilerplate code for WebGL and Three.js can be tedious (setting up renderers, cameras, lights, orbit controls, etc.). - **The Solution:** I integrated an AI assistant directly into the Monaco editor. You can prompt the AI in English or French to build a scene (e.g., *"create a glowing wireframe grid with rotating metal spheres"*), and it compiles and runs the WebGL code in real-time. ### 👥 2. Real-Time Multiplayer Sandbox (DevSocial Hub) Coding is better with friends. I wanted a way for developers to pair program in 3D: - **Real-time Sync:** Powered by Firebase, multiple developers can join the same room code and code simultaneously. - **3D Laser Cursors:** We created synchronized 3D raycasting cursors, so you can point at elements in the 3D preview and your teammate sees exactly where you are looking. - **WebRTC Voice Chat:** No need for Discord or Zoom. We built high-fidelity peer-to-peer microphone voice channels directly into the browser tab using WebRTC. ### ⏪ 3. DVR Time-Travel Debugger & Time Machine (Local Version Control) - **DVR Panel:** A floating panel that lets you travel back and forth between execution states to see how variables change. - **Time Machine History:** Automatically takes local snapshots of your code every 5 minutes and lets you restore any version with 1-click. All snapshots persist in `localStorage` so they survive page refreshes! ### 📦 4. Standalone 1-Click Compiler Once you are happy with your 3D creation (like our prebuilt *Steampunk Chrono* or *Webcam Avatar* widgets), you can export the entire workspace as a single, self-contained, offline-ready HTML file or a ZIP bundle. --- ## 🛠️ The Tech Stack I wanted the application to load instantly and run smoothly, so I opted for a lightweight stack: - **Frontend:** Vanilla HTML5, CSS3 (Glassmorphism design system), and Modern ES6+ JavaScript. - **3D Engine:** Three.js (WebGL renderer, OrbitControls). - **Editor:** Monaco Editor (the core engine behind VS Code). - **Database & Sync:** Firebase (Firestore real-time listeners for cursor sync, Auth, and Hosting). ## * **WebRTC Protocol:** RTCPeerConnection API with Firestore-based signaling for the voice channels. ## 🚀 Try It Out! The platform is live and offers a **Preemium plan**: - 🎁 **Free Tier:** You can try 3 of our interactive components/widgets completely free of charge. - ⚡ **Pro Tier ($10/month):** Unlock the full power of the AI co-pilot, real-time multiplayer coding sandboxes, custom 3D vector extruders, and unlimited exports. 👉 **Live Website:** [https://ia-codestudio.com](https://ia-codestudio.com) I would love to get your feedback: - What features should we add next? - How does the platform feel?
