I built a Real-time Restaurant POS using React & Firebase (to replace expensive SaaS)

#webdev #showdev #react

The Problem 🚫

Local restaurants are bleeding money. They pay huge monthly subscription fees for POS systems that are often slow and clunky.
I realized that with modern web technologies, I could build a solution that is faster, cheaper, and runs on any device.

So, I built RestoManager.

The Tech Stack 🛠️

I wanted speed and real-time capabilities, so I chose:

Frontend: React 18 + Vite (Blazing fast build times)
Styling: Tailwind CSS (Clean, dark-mode UI)
Backend/DB: Google Firebase (For Auth & Realtime Database)
Mobile: PWA (Progressive Web App) - installable on iPad/Android without an App Store.

The Challenge: Real-Time Sync ⚡

The hardest part was the Kitchen Display System (KDS).
When a waiter punches an order at Table 5, the kitchen needs to see it instantly. No page refreshes allowed.

I used Firebase's onValue listeners to create a live socket connection. The latency is practically zero. It feels like magic.

I recorded a quick demo showing the order flow from the Waiter App to the Kitchen Screen.

I've made this project available as a White-Label solution.
If you are a developer looking for a solid base to sell to your local clients (or just want to study the architecture), you can grab the full source code.
