🌐 Live Demo • 📖 Documentation • 🚀 Quick Start • 🏗️ Architecture • 📋 API Reference

📋 Overview

Stock.os is an enterprise-grade inventory command center designed for retail businesses, wholesalers, and mid-size operations teams. It provides a unified platform to control stock movement, prevent stockouts, and make data-driven inventory decisions with real-time dashboards and analytics.

🎯 Key Value Propositions

Feature	Benefit
Real-time Inventory Tracking	Know stock levels instantly across all warehouses
Automated Alerts	Get notified of low stock and critical inventory events
Role-based Dashboards	Admins, Managers, and Staff see data relevant to their role
Multi-warehouse Support	Manage inventory across multiple physical locations
Cloud-native Deployment	Production-ready deployment on AWS with auto-scaling
Barcode Integration	Quick product lookup and scanning capabilities
Advanced Analytics	Demand forecasting, trend analysis, and insights
Production Ready	Enterprise security, ACID transactions, and 99.9% uptime SLA

🌐 Live Environment

The system is currently deployed on AWS production infrastructure:

Component	URL/Details
Frontend	https://d15os9kcan23ap.cloudfront.net
API Base	https://d15os9kcan23ap.cloudfront.net/api
Custom Domain	stock.os (see custom domain setup below)
CDN	CloudFront (E1YKXYS6CAYRVP)
Backend	EC2 (ap-south-1) + RDS MySQL

Demo Credentials (auto-initialized on first run):

Username: admin
Password: admin1234@
Email: admin@stock.os

🔗 Custom Domain Setup (stock.os.cloudfront.net)

Want to use a professional domain like stock.os instead of the CloudFront ID?

✅ See Phase 6 in AWS Deployment Guide for step-by-step instructions to:

Register a domain (Route 53, GoDaddy, Namecheap, etc.)
Create SSL/TLS certificate in AWS Certificate Manager
Configure CloudFront with custom domain
Set up DNS CNAME/Alias records
Enable HTTPS with your domain

This takes approximately 15-30 minutes of setup time.
