Site Monitor

If your website goes down and you don't know about it, your customers do. Site Monitor checks your URLs at regular intervals, measures response time, watches SSL certificate expiry dates, and detects unexpected content changes. When something goes wrong, you get an alert within seconds — not hours later when a customer emails you.

What It Does

• Checks your websites every 1-15 minutes and alerts you within 30 seconds of downtime
• Tracks response time trends and warns you when performance degrades before it becomes a problem
• Monitors SSL certificates and sends warnings at 30, 14, and 7 days before expiry

How It Works

1. Add the URLs you want to monitor during setup — homepages, API endpoints, login pages, etc.
2. Set your check frequency and alert preferences.
3. Get instant alerts on downtime and a weekly performance report showing uptime percentage and response trends.

Works With

• Any public website or API endpoint
• Slack, Discord, Telegram (instant alerts)
• PagerDuty, Email
• Webhooks (for custom integrations)
