Your biggest risk is building a scraper that breaks the moment a retailer updates their HTML structure. I've seen three projects fail because they treated scraping as a one-time build instead of an ongoing maintenance contract. If Target or Best Buy changes a CSS class, your alerts stop working and you won't know until users complain. Before I map out the architecture, I need clarity on two things. First, which retailers are you tracking - do any of them offer official APIs, or are we scraping all of them? Second, what's your expected product volume - are we monitoring 50 items or 5,000, because that changes whether we use polling or webhooks. Here's the technical approach: - FLUTTER + FIREBASE: Single codebase for iOS and Android with Cloud Messaging for sub-second push notifications that work even when the app is closed. - PHP WORKER + REDIS: Background job queue that staggers API calls to avoid rate limits and caches responses to reduce redundant requests by 80%. - PUPPETEER + PROXY ROTATION: Headless browser scraping with residential proxies and automatic retry logic when retailers block requests or change selectors. - POSTGRESQL + TIMESCALEDB: Time-series database optimized for price history queries, letting you chart 90 days of data without performance degradation. - TWILIO + SENDGRID: SMS and email fallback alerts with templating so you can customize which events trigger which channels. I've built two similar systems - one for a sneaker reseller tracking 12 retailers and another for a price comparison startup monitoring 40K products. Both are still running after 18 months because I built selector fallbacks and health checks that alert me when scrapers break. Let's schedule a 20-minute call to walk through your retailer list and discuss whether we need anti-bot measures before you commit budget.

@bridgestonetech1

Hello, I’ve built systems similar to what you’re describing real-time product tracking with alerts so your requirement is very clear to me. The key part here isn’t just the UI, it’s building a reliable tracking engine that can monitor multiple retailers without breaking due to rate limits or site changes. I would structure this with a queue-based worker system (Node.js + Redis) that continuously checks price, stock, and target thresholds, and instantly triggers alerts. For apps, I’d go with React native/Flutter so you get iOS + Android from a single codebase, with push notifications handled via Firebase. The web dashboard will allow quick product input (URL/SKU), retailer selection, and a simple price history view. I’ll keep everything clean and modular so scaling to more products or retailers later won’t be an issue. You’ll also get proper documentation so you’re not dependent on me for updates. Timeline: 3–4 weeks for a solid MVP One thing I want to clarify before starting: Which retailers are you planning to track first? APIs available or scraping needed? Let’s connect and plan the architecture so we can move forward quickly.

@Ak230598

I can make price tracking system as per your requirements. I have 6+ years of experience in this field. Let's connect and discuss more about your requirements. Thank you.

@nadeemkhan7

Hi, A responsive web dashboard plus native iOS/Android apps from one shared codebase meets your need for fast, consistent tracking across devices. I will use Flutter to ship companion apps and a clean admin UI, while reliable background workers poll retailer APIs or carefully built scrapers, honoring rate limits and scaling as your product list grows. I’ll wire real-time push notifications for price changes, stock status, and target dips, with email/SMS toggles per item. Products can be added via URL or SKU, thresholds set per retailer, and a lightweight history chart visualizes trends to guide buying decisions. My approach emphasizes low-latency alerts and graceful degradation under load. With 10+ years building scalable mobile and web systems, I will deliver well-commented code, setup docs, and a deployable stack using RESTful services, background jobs, and cloud-ready architecture. Timeline includes discovery, MVP core tracking, alerting, and phased polish for release. Lets connect in chat so that we discuss further. Regards, Mohd Nadeem Khan

@nathanholmes

Tracking products across multiple retailers with real-time alerts sounds straightforward, but the real challenge is building a reliable polling system that respects rate limits while still delivering near-instant notifications as your product list scales. I’d structure this with a central backend handling product tracking, a queue-based worker system for polling APIs/scraping, and event-driven alerts for price drops or stock changes. The frontend can be a responsive web dashboard, with mobile apps built from a shared codebase (Flutter or React Native) connected to the same API. Push, email, and SMS alerts would be configurable per product. I’ve worked on data-driven tracking systems and notification flows, so I’m comfortable designing something stable and scalable from the start. Happy to outline a simple architecture or rollout plan if useful.

@tristanvdheever1

I recently completed a stock-monitoring app for a mid-sized e-commerce startup that tracked product prices and stock levels across multiple retailers using API integrations and intelligent scraping. I specialize in building scalable, cross-platform apps using Flutter, delivering seamless experiences on web, iOS, and Android from a single codebase. I can develop your web dashboard and companion apps with real-time push notifications, flexible alert settings (push, email, SMS), and a background worker that respects API limits and scales smoothly. The interface will feature quick product entry, retailer selection, and price history charts. Clean code and concise documentation will be provided for easy future updates. I would love to chat with you about your project, no pressure! The worst case scenario is you walk away with a free consultation and a good conversation. :) Kind Regards, Tristan Van Den Heever
