About KosmoKode: 3D EdTech Platform
3D Multiplayer RTS where players learn JavaScript by programming a space fleet.
🚀 Stop teaching coding with boring text consoles. Let them command a space fleet! KosmoKode is a fully developed, browser-based 3D educational platform (EdTech) that bridges the gap between gaming and learning. Players write real JavaScript code (or use a visual block editor) to control spaceships, manage resources, and fight in real-time multiplayer battles. I built this as a passion project, and it has evolved into a highly scalable, ready-to-launch product. It is perfectly positioned for the booming EdTech market, coding bootcamps, or as a B2C indie game. 💡 The Core Value (Why it's unique): Unlike platforms where you just move a character through a maze, KosmoKode is a tactical RTS. Players must use loops (while, for), conditions (if/else), and asynchronous programming (Promise.all) to create complex AI for their fleet (e.g., "Find the weakest enemy, flank them, and retreat if HP is low"). 🔥 Key Features: Dual Coding System: Beginners can use the intuitive Visual Block Editor (built with jsPlumb). Advanced players use the Text Editor (CodeMirror) with syntax highlighting and auto-complete. Real-Time Multiplayer (PvP & Co-op): Custom Node.js + WebSockets backend. Features multiple game modes including Free-For-All, Team Deathmatch, and a tactical "Sabotage" mode. 👨‍🏫 The "Teacher Hub" (B2B Goldmine): A dedicated dashboard for instructors. Teachers can create private rooms, monitor students' code in real-time, toggle hints, and launch specific educational scenarios for the whole class. High-Performance 3D Engine: Powered by Three.js. Highly optimized using InstancedMesh for rendering asteroid fields and particle systems without dropping FPS. Community Codex (Social Hub): Players can share their best algorithms, upvote/downvote scripts, and import others' code into their own editor. Accessibility (a11y) Built-in: Voice control (dictate code), screen reader support, and colorblind mode included. 🛠Tech Stack: Frontend: Vanilla JS (ES6+), Three.js (3D rendering), CodeMirror (code editor), jsPlumb (block editor), HTML5/CSS3. No heavy frameworks, extremely fast and easy to maintain. Backend: Node.js, WebSockets (ws library) for low-latency game loop (80ms tick rate), MySQL for user data and inventory. Security: JWT Authentication, bcrypt password hashing, Web Worker isolation (user code is executed in a sandboxed Web Worker to prevent infinite loops from crashing the UI). 💰 Monetization Potential: B2B SaaS: Sell access to coding schools, STEM camps, and high schools using the built-in Teacher Hub. B2C Freemium: Free to play, but users pay for premium ships, cosmetics, or advanced AI slots in the built-in Store/Shipyard. White-label: Sell the engine to existing EdTech giants. 📦 What’s Included in the Sale: 100% Source Code (Frontend & Backend). Full Intellectual Property (IP) rights. All 3D models, textures, and audio assets. Database schemas. 1 month of technical support and handover to ensure you are fully set up. If you are looking for a turnkey EdTech product with a massive "wow" factor, let's talk!

Reason for selling
I am a solo technical founder and developer. I spent months building the core engine, the 3D graphics, the multiplayer backend, and the educational curriculum. The product is now 100% complete from a technical standpoint. However, I realize that to make this successful, it requires marketing expertise, B2B sales skills (to pitch to coding schools), and community building—which are not my strong suits. I want to pass this project to someone with marketing/sales experience or an existing EdTech company that can put this amazing tool into the hands of real students. I also need to free up my time for a new backend infrastructure project.
