WatchCron

Cron job and heartbeat monitoring with uptime, port, SSL, domain, and blocklist checks

WatchCron is a monitoring platform for scheduled tasks and infrastructure. Cron jobs are monitored via heartbeat pings to a unique URL per check, with configurable grace periods and run history. It also provides HTTP/HTTPS uptime checks (as often as every 30 seconds from multiple regions), TCP/UDP port and DNS record checks, SSL certificate and domain (WHOIS) expiry monitoring, DNS blocklist (RBL/DNSBL) scanning for IP ranges, Cloud Cron for scheduled HTTP requests with retries, and public status pages. Alerts route to 22 channels including Slack, Telegram, Discord, Teams, PagerDuty, OpsGenie, email, SMS, voice, and WhatsApp. A REST API is available.
