Scheduled-job reliability analyzer

Cron Doctor

Understand your scheduled job before it runs.

Cron Doctor parses the actual schedule, previews the next runs, checks shell and monitoring behavior, and shows evidence for every finding. No AI guesses in the diagnosis path.

Analyze a scheduled job

Unix cron, GitHub Actions, Kubernetes, systemd, or Laravel

Scheduler sourceExampleScheduler configuration (cron expression or crontab, YAML, timer, or PHP)

Unix fallback timezone

The fallback applies only to Unix cron; CRON_TZ takes precedence. Other schedulers require their own configuration context. Systemd host timezone is not supplied here, so exact runs remain unknown.

Your configuration is sent to PingCron for analysis. It is not saved and is never executed. Secret-like values are redacted from returned evidence.

Your reliability report appears here

Cron Doctor explains the schedule, calculates upcoming runs, and checks the configuration for reliability risks with evidence.

Parse what actually runs

Expression, crontab environment, aliases, timezone, and command context are analyzed as one job.

Show the evidence

Every actionable finding is tied to supplied configuration instead of an opaque AI opinion.

No command execution

Cron Doctor analyzes text. It never shells out to or executes the job you paste.

Catch silent failure paths

Find heartbeat placement, exit-status, schedule, timezone, and configuration risks before they become incidents.
