Competitor Price Monitor

If competitors cut price overnight (or run a flash sale), you want to know quickly — and you want proof you can act on. Competitor Price Monitor tracks the product pages you care about, stores every check in your own history database, and alerts you when prices change or cross your thresholds.

This is downloadable software you run yourself. Your URLs, alerts, and price history stay private.

• Monitors a list of competitor product URLs on a schedule (hourly, daily, or custom)
• Detects price changes and sale events based on your thresholds (percent drop or target price)
• Stores a complete price history in SQLite (so you own the data)
• Sends alerts to your preferred channel: email, Slack, Discord, or webhooks
• Exports history to CSV/JSON for analysis and reporting
• Includes anti-detection measures (random delays, user-agent rotation) to reduce blocking risk

• E‑commerce operators who want fast awareness of competitor price changes
• Teams running promotions who need to react to undercutting or sales
• Anyone who wants a self-hosted alternative to per‑SKU SaaS monitoring fees

You receive a ZIP package that includes:

• A monitoring script (async-capable) designed for multi-URL checks
• A multi-site configuration system for your URL list and thresholds
• SQLite storage for historical prices
• Alert module (email, Slack, Discord, webhook)
• Export tools (CSV/JSON)
• Scheduling templates (cron) to run unattended
• Site extractors (platform-specific where available + a generic fallback)

[Image placeholder: Config file example (URLs + thresholds)]

• Competitor product URLs to monitor
• Check frequency (hourly/daily/custom)
• Alert thresholds (percent drops and/or target price points)
• Alert channels (email address, Slack webhook, Discord webhook, etc.)
• Optional: proxy list (helpful at higher volumes or stricter sites)

1. Add URLs and thresholds to your config 2. Run a baseline check to store starting prices 3. Enable alerts for the channels you care about 4. Schedule it (cron) and review alerts + history exports as needed

Will this work on Amazon/eBay/Shopify/WooCommerce? It’s designed to support major platforms and generic pages. Some sites change markup frequently; if a page structure changes, an extractor may need adjustment.

Will I get blocked? High-frequency monitoring can trigger blocks on some sites. The tool includes random delays and user-agent rotation; proxies can help at scale.

Where is my data stored? Locally in a SQLite database file generated by the tool. You own the full history.

Can I monitor dozens/hundreds of URLs? Yes. Practical limits are your schedule, network constraints, and whether you need proxies for reliability.
