Website Availability Monitor & Change Detection

🚀 Smart Website Change Detection Monitor (Pay Only for Real Changes)

Monitor websites for availability and meaningful updates — and only pay when something actually changes.

This Actor is designed for reliable, long-term monitoring, not aggressive scraping. It detects page changes using stable signals (HTTP status + page title) and ensures consistent, production-ready output.

💡 Why This Actor?

Most monitoring tools charge per run or per request.

❌ You pay even when nothing changes ❌ You waste credits on empty or unchanged results

👉 This Actor is different.

💸 Smart Charging Model

✔ New page detected → Charged ✔ Page changed → Charged ❌ No change → FREE ❌ Blocked / error → FREE

You only pay when real, meaningful updates happen.

🎯 Core Features 🔍 Change Detection Detects new and updated pages Tracks title changes and HTTP status ⚡ Lightweight & Efficient Minimal resource usage Fast execution for scheduled monitoring 🛡️ Reliable Monitoring Design Retry logic for unstable pages Handles blocked or error responses gracefully 📊 Clean Structured Output API-ready JSON format Consistent fields across runs 🔁 Built for Scheduling Run hourly, daily, or weekly Ideal for automation pipelines 💼 Real Use Cases 🧑‍💼 Job & Hiring Monitoring
