I Monitor 50+ Websites for Free Using Apify Scheduled Runs

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 All free on Apify Store — search knotless_cade
