A QR-Powered Restaurant OS.

February 12, 2026 I built a QR-based Restaurant OS in Flask — looking for brutal feedback

Hey everyone 👋

I’ve been working on a full-stack QR-powered restaurant management system called MyCafe.

The idea started from a simple observation:

Even today, most dine-in restaurants rely on waiters for basic ordering flow, which creates delays, miscommunication, and friction.

So I built a lightweight “Restaurant OS” where:

Customers scan a QR at their table

Browse menu + order instantly

15-minute edit window before kitchen lock

Real-time order status updates

Automated GST + service charge billing

Admin dashboard with force actions

Table session isolation

Order locking once preparation starts

Tech stack:

Flask (Python)

SQLite

Vanilla JS

Custom admin + kitchen display system

This is not meant to compete with delivery giants — it’s focused purely on improving the dine-in experience without heavy commissions.

I’m looking for honest feedback from:

Backend developers

Product thinkers

Indie hackers

Anyone who has built SaaS tools

What would you improve? What feels unnecessary? What feels strong?

Appreciate any brutal feedback 🙌

Restaurants still rely on waiters for basic tasks like taking orders, updating status, and generating bills. This creates delays, miscommunication, and unnecessary operational friction. I wanted to build this
