Free Website Monitoring Tool | PageRadar: Uptime, Performance & User Behavior

About Pageradar.io

PageRadar is your 24/7 website guardian – a completely free monitoring tool that catches critical issues before they cost you customers. As a bootstrapped SaaS founder, I nearly lost $3,000 in Black Friday sales when my checkout page silently failed at 2 AM. Traditional tools like UptimeRobot only pinged server status, missing the real problem. PageRadar saved me with its three-layered free monitoring:

  1. Uptime Radar

    • Checks servers/APIs every 60 seconds

    • SMS/email alerts for outages

    • Status pages for customer transparency

  2. Performance Pulse

    • Tracks page speed across 12+ locations

    • Waterfall analysis for slow assets

    • Core Web Vitals reporting

  3. Session Spyglass

    • Records real user interactions (clicks, scrolls)

    • Reveals JS errors & broken flows

    • Heatmaps of UX friction points

Unlike freemium tools (Datadog, New Relic), PageRadar’s free tier includes:
✅ 3 monitors (websites/APIs)
✅ 50,000 monthly session recordings
✅ Unlimited alert channels
✅ 90-day data retention
✅ No credit card required

Ideal For:

  • E-commerce stores are avoiding revenue leaks

  • Developers are debugging production issues

  • Marketers optimizing conversion funnels

  • Startups with zero monitoring budget
