How I built a 3D Cyberpunk Hypercar Dealership with FastAPI and Three.js 🚗💨

Hello fellow developers! 👋

Most web templates today are either static, visually flat HTML pages or complex admin dashboards with zero visual flair. As a software engineer who loves automotive content, I wanted to build something that bridges the gap between heavy, stunning 3D frontend graphics and a robust, production-ready backend.

So, I built NEXUS-9 — an ultra-futuristic, Cyberpunk-themed 3D Hypercar Dealership web application.

Here is a breakdown of how I built it and the tech stack I used.

🛠️ The Tech Stack

I wanted this project to be fully deployable and customizable, so I split the architecture into a solid API and a dynamic visual frontend:

Frontend: HTML5, CSS3 (Glassmorphism UI), Vanilla JS.
3D Graphics & Animations: Three.js (WebGL) for rendering the car models, and GSAP for cinematic transitions.
Backend: Python 3.x, FastAPI, Uvicorn.
Database: SQLite via SQLAlchemy for managing the car catalog and live orders.

✨ The Coolest Features

1. Interactive 3D Chassis Inspector
Instead of just showing images of cars, I integrated a full Three.js canvas. Users can drag 360°, zoom in on details, dynamically change the metallic paint colors (Cyan, Magenta, Gold), and even toggle a blueprint/wireframe mode.

2. Cinematic UI & Web Audio
To give it that true Cyberpunk feel, I added a hyper-speed quantum warp background, screen shake intro, and neon smoke effects. I also used the Web Audio API to simulate a synthetic V12 engine rev sound when interacting with the UI.

3. Secure Admin Command Center
It's not just a pretty frontend! I built a password-protected admin dashboard using FastAPI. The admin can log in to track a live registry of orders (date, time, customer info), check total revenue metrics, and view transmissions from the contact form.

I built this template to be the perfect starting point for developer portfolios, high-end agency projects, or for anyone wanting to learn how to integrate WebGL with a real Python backend.

If you want to skip the setup and use this code for your own projects, I've made the complete, optimized source code available here:

It comes fully documented and ready to run out of the box!

I would love to hear your thoughts on mixing Three.js with FastAPI. Have you guys built any hybrid 3D web apps recently? Let me know in the comments! 👇
