This project is a masterclass in what “vibe coding” can produce when paired with real technical skill.
Try It Yourself
This game runs directly in your browser—no installs, no setup. Just jump in and start playing.
Drag from your blue planets to send fleets across space. Take control of neutral gray worlds before the AI reaches them. As your ships travel, you’ll even see tiny laser flashes when they clash with enemy units mid-flight.
The controls are simple and intuitive:
Drag from your planet → Send ships to attack
Drag empty space → Rotate the camera
Scroll → Zoom in or out
Click any planet → Focus the camera on it
Once you start playing, it all feels natural within seconds.
If you know basic HTML and JavaScript, you can create something powerful like this 3D space strategy game
Let’s break it down in a way anyone can understand.
<ol>
<li>What You Actually Need (No BS)</li>
</ol>
You don’t need a game engine like Unity.
You only need:
HTML → structure
CSS → styling
JavaScript → logic
A library → we use Three.js (for 3D graphics)

A walkthrough of building a 3D browser-based space strategy game using only HTML, CSS, JavaScript, and Three.js — no game engine required. The game features fleet management, AI opponents, camera controls, and mid-flight combat effects, all running directly in the browser. The post frames the project as an example of what vibe coding can achieve when combined with foundational web skills.
