Continuous Heartbeat Monitoring
When standard uptime checks aren't enough. Have your services actively report their health status directly to us, completely bypassing firewalls.
Monitor the Unreachable
Perfect for internal services, IoT devices, and strict network environments.
Behind Firewalls
Monitor internal databases or private microservices without exposing them to the internet.
Daemon Processes
Send a pulse every minute from your background queue workers to prove they are alive and processing.
IoT Device Health
Ensure physical devices or remote edge nodes are connected and operating correctly.
Dead-Simple Integration
Send an HTTP request from anywhere. That's it.
Define Expected Interval
Tell us how often we should expect to hear from your service (e.g., every 5 minutes).
Send the Ping
Fire a quick and lightweight HTTP GET/POST request from your application code.
fetch("https://ping.cronrabbit.com/your-unique-id");
}, 60000); // Send every minute
Instant Alerts on Silence
If the expected time passes without a ping, your monitor marks as "Down" and orchestrates your notifications.
Powerful Customizations
Adapt the heartbeat monitor exactly to your workflow.
Custom Failure Thresholds
Don't want to be alerted on a single missed ping? Set a threshold of 3 missed pings before triggering a downtime event.
Payload Metrics (Beta)
Send custom JSON data along with your heartbeat POST request (e.g. Memory Usage, Active Users) to track trends directly in the UI.
