CronAlert sends HTTP requests to your URLs at the interval you configure (as often as every 30 seconds). We check the response status code, response time, and optionally the response body for specific keywords. If anything looks wrong, we alert you immediately.
When we detect a failure, we confirm it with a second check from a different region to avoid false positives. If the failure is confirmed, we immediately send alerts through all your configured channels (email, Slack, Discord, webhook, etc.) and open an incident. You'll also get notified when it comes back up.
Yes. You can monitor any HTTP/HTTPS endpoint, including REST APIs, GraphQL endpoints, and webhook URLs. You can configure custom headers, request methods (GET, POST, PUT, etc.), request bodies, and expected response codes.
Yes. With heartbeat monitoring, CronAlert gives you a unique URL that your cron job pings on each run. If we don't receive a ping within the expected window, we alert you that the job may have failed or stalled.
We guarantee 99.99% uptime for our monitoring infrastructure, backed by a formal SLA on Team and Business plans. Our infrastructure runs on Cloudflare's global edge network across 300+ locations, so even regional outages don't affect our ability to monitor your services.
