Stockly

Hey Indie Hackers! 👋

I'm Nazmul, a software engineer and the creator of Stockly — a real-time inventory monitoring, predictive stockout prevention, and automated back-in-stock alert engine built for Shopify stores.

I wanted to share why I built this, the technical decisions behind it, and what I’ve learned from talking with e-commerce merchants.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━

💡 THE PROBLEM: STOCKOUTS ARE SILENT REVENUE KILLERS

Every e-commerce merchant knows the pain of spending money on ads and marketing, only for a hot-selling product to suddenly hit "Out of Stock."

When looking into how stores handle this today, I noticed three major flaws:

1. The Reactive Alert Trap: Standard low-stock emails get buried in crowded inboxes. By the time a merchant notices, supplier lead times make a multi-week stockout inevitable.

2. App Fragmentation: To manage the restock lifecycle, merchants were paying for 3 to 4 separate subscriptions (one app for low-stock alerts, another for customer "Notify Me" popups, and another for Purchase Orders).

3. Lost Customer Intent: When a product is out of stock, customers bounce to competitors instead of being automatically captured on an automated restock waitlist.

🛠️ WHAT IS STOCKLY?

I built Stockly to connect the entire inventory lifecycle in one real-time command center:

• Sub-Second Sync: Webhook-powered architecture tracking stock changes across all locations instantly. • Multi-Channel Alerts: Critical low-stock notifications sent directly to Email, WhatsApp, and Slack Connect. • Automated Back-in-Stock Notifications: A clean, no-code "Notify Me" form on product pages that automatically emails shoppers the second items return to stock. • Predictive Stockout Forecasting: 30-day sales velocity analytics predicting "~days left" before stockouts and auto-calculating optimal reorder dates. • Purchase Orders & Carrier Tracking: Multi-currency PO creation with live tracking across 2,400+ global shipping carriers. • Ecosystem Automations: Native triggers for Shopify Flow and Klaviyo marketing flows.

💻 TECH STACK & ARCHITECTURE:

• Frontend: React, React Router / Remix, Shopify Polaris • Backend: Node.js, TypeScript, Shopify GraphQL Admin API • Database & Caching: PostgreSQL, Prisma ORM, Redis • AI Extraction: Google Gemini AI (for extracting supplier and product metadata) • Hosting: Modern cloud container infrastructure
