CronPulser
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.

Ping Clock
Ping Clock monitors cron jobs, backups, scheduled tasks and background workers through heartbeat pings. Unlike uptime monitors that check services responding to requests, it can detect when a scheduled job stops running. Each job pings a unique URL when it runs, and missed pings trigger alerts. Set a period and grace time or a cron expression in any time zone. Start, success and fail pings show whether a job never ran, failed or hung, and the job can send its exit code. Email and Slack alerts are available on every plan, with Microsoft Teams, Discord and webhooks on Starter and higher. Pro adds run-duration tracking, log capture and an API. The Free plan includes 20 checks with no credit card required.
