Monitor Dynamic Website Changes with Firecrawl, Sheets & Gmail Alerts

This n8n workflow is designed to track changes on dynamic websites, such as React apps or JavaScript-rendered pages, that traditional scrapers can't handle. Triggered by a webhook (ideal for cron scheduling), it uses the Firecrawl API to scrape the latest content, compares it against historical data stored in Google Sheets, and sends Gmail notifications only when meaningful changes are detected. It maintains a complete log in Sheets for auditing and trend analysis, ensuring reliability even if individual components fail.

Key benefits include spam-free alerts, robust handling of modern web tech, and seamless integration of scraping, storage, and notification services. It's bulletproof with error handling and perfect for deployment in production environments. Users save hours of manual checking while gaining actionable insights from automated monitoring.

Ideal use cases: Competitor price tracking, job posting alerts, product stock updates, news site monitoring, API doc changes, or terms of service updates. Setup requires Firecrawl API key, Google Sheets/Gmail OAuth credentials, and a prepared Sheets doc with 'Log' and 'comparison' tabs.
