Building MovieSync in Public (with Antigravity) 🎬🚀
We’ve all faced this…
You step out during a movie break, thinking you’ll grab snacks or use the washroom quickly — but end up stuck in long queues. Short break, long wait.
That’s where the idea of MovieSync came from.
The Problem
Intermissions are limited, but there’s zero visibility on crowd levels. You just guess… and sometimes regret it.
The Idea
I built MovieSync, a real-time dashboard that shows how crowded different areas are inside a venue.
Simple color signals help you decide instantly:
🟢 Low crowd
🟠 Medium
🔴 High congestion
No guesswork. Just smarter decisions.
Tech Stack
- React + Vite for a fast, lightweight frontend
- Vanilla CSS (no heavy UI libraries)
- Docker (multi-stage build)
- Nginx for serving the app
- Google Cloud Run for serverless deployment
- Antigravity to speed up development & workflow
How I Built It
I focused on keeping things simple and clean.
Instead of using UI frameworks, I designed everything from scratch using glassmorphism styles, smooth transitions, and subtle animations.
Since I didn’t have real sensors, I created a simulation that mimics real-time data (like WebSockets). The dashboard updates dynamically to reflect crowd density.
Deployment
Used Docker with a multi-stage build:
- Node → build optimized assets
- Nginx → serve the app on port 8080
Deployed on Google Cloud Run for automatic scaling.
Where Antigravity Helped
Antigravity made a big difference by:
- Speeding up initial setup
- Making UI iterations faster
- Simplifying deployment flow
- Reducing overall complexity
It helped me move faster from idea → working product.

Final Thought
This project showed me how quickly you can build something useful using the right tools. Building in public also made the journey more real and accountable.
