Alerts you only when a failure is confirmed. 100% free, open source alternative to Pingdom, UptimeRobot and Better Stack.
Uptime monitoring that tells you what to do. Detects broken layouts, dead databases behind a 200, slow pages with the cause, vulnerable versions, expiring certificates and silent cron jobs. One read-only link per client. Self-hosted PHP, zero dependencies, plain shared hosting.
A lightweight Python CLI that periodically checks and warms selected website URLs to improve responsiveness, monitor uptime, and support small/shared-hosted websites without aggressive traffic.
