Scheduled-job reliability analyzer

Cron Doctor

Paste a cron job. See what can fail before production teaches you the hard way.

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 Unix cron job
5-field cron, aliases, or one full crontab line

Nothing is uploaded or executed outside the analysis request. Cron Doctor never runs your command, and secret-like values are redacted from returned evidence.

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.
