Built for developers who hate silent failures.
Cron jobs break. Servers restart. Scripts crash. CronShieldLabs provides the heartbeat monitoring you need to ensure your background tasks are actually running.
Domain Expiry Monitoring
Track registry expiry dates and receive alerts at approximately 30, 14, 7, and 1 day before renewal is due. Read the domain-health guide.
DNS Change Detection
Record A, AAAA, MX, NS, and CNAME values and alert account owners when the normalized DNS snapshot changes.
Website Uptime Monitoring
Check public HTTP and HTTPS websites automatically, track response status and time, and confirm failures before alerting. Read the uptime setup guide.
SSL Expiry Alerts
Record certificate expiry dates and notify account owners when a monitored HTTPS certificate has 30 days or less remaining.
Safe Redirect Checking
Follow a limited redirect chain while revalidating every destination and blocking private, local, and reserved network targets.
Reliable Schedule Tracking
Tell us when your job is supposed to run (Every minute, hourly, daily, or weekly). We watch the clock so you don't have to.
Instant Alerting
The second a script misses its check-in window, we fire off an email alert directly to your inbox. Catch the failure before your customers do.
Zero-Bloat Integration
No heavy SDKs or complex API configurations. Just copy and paste a single secure ping URL to the end of your bash script or PHP file.
Grace Period Logic
Network latency happens. Our intelligent watchman script builds in a slight grace period to prevent false alarms for jobs that are just running a few seconds late.
Clean Telemetry History
Log into your dashboard to see a real-time list of all your active monitors, alongside a detailed history of their most recent successful pings.
Secure Architecture
Every new monitor uses a high-entropy private token, and ping traffic is rate-limited to reduce guessing and telemetry abuse.
Stop wondering if your backups ran last night.
Set up your first monitor in under 60 seconds.
