Apify has a built-in scheduler that runs your actors on a cron schedule. Combined with free-tier actors, you get free monitoring.
What I Monitor
- Uptime — is the site responding? What's the response time?
- SSL certificates — are any expiring within 30 days?
- Security headers — HSTS, CSP, X-Frame-Options present?
- Broken links — any new 404s since last check?
- Tech stack changes — did a competitor switch frameworks?
How It Works
- Create an actor (e.g., SSL Certificate Checker)
- Set up a scheduled run (daily, hourly, weekly)
- Actor runs automatically and stores results
- Set up email/Slack notifications for failures
Cost
Apify free tier gives you enough compute for basic monitoring. Most of my tools run in under 10 seconds and use <256MB RAM.
The Toolkit
- Website Uptime Checker — status codes, response times
- SSL Certificate Checker — expiry alerts
- HTTP Headers Checker — security score
- Broken Links Checker — find 404s
- Tech Stack Detector — track changes
