WatchCron

Healthchecks.io is a simple and effective cron job monitoring tool that alerts users when their scheduled tasks, such as backups or reports, fail to run on time. Users can generate a unique ping URL for each background job, and the platform sends notifications when jobs do not ping within the configured timeframe. It supports 20 free cron job monitors and features an easy-to-use dashboard where users can name, tag, and organize their tasks. With configurable period and grace time settings, users can track tasks across various states, such as "up," "late," or "down," based on the timing of pings. Healthchecks.io also supports cron expressions, logs event history, and offers status badges for public display. Notifications are available through multiple integrations, including email, webhooks, Slack, and Discord, as well as incident management tools like PagerDuty and Opsgenie. The service is ideal for monitoring cron jobs, server processes, database backups, SSL renewals, and more.

CronPulser is a hosted cron job scheduler for developers and IT/operations teams. It schedules HTTP requests to APIs and webhooks with configurable cron expressions, time zones, methods, headers, payloads, retries, and execution history, and can alert on failed, slow, or missing runs. Its open-source Runner connects outward from private Linux and Windows Server machines to run allow-listed local commands, capturing status, duration, exit code, and output without requiring inbound ports or SSH. Scheduled TLS certificate checks report expiry information alongside other jobs. Email alerts are available on every plan, while webhook alerts are included on paid plans. Pro and Scale plans add a REST API and Model Context Protocol (MCP) access for scripts and compatible AI clients to manage jobs. Free and paid plans provide different active-job capacity and log-retention limits.
