The useful details.
What is Nightjar?
Nightjar is a private run ledger and failure inbox for scheduled scripts on macOS. It records output, exit code, and duration for every run, then sends a native notification when a job fails, times out, or is missed.
Isn't cron free?
Yes. Cron schedules commands well, but it does not keep useful history or alert you when something breaks. Nightjar adds the record and the warning. You are paying to know what happened.
Does Nightjar replace cron?
For scheduled jobs on your Mac, yes. Nightjar runs jobs with its own scheduler and can import your existing crontab. Your scripts do not need to change.
What happens while my Mac is asleep?
Jobs run while your Mac is awake and the Nightjar agent is active. If sleep or shutdown causes a scheduled run to be missed, Nightjar flags it when the machine returns.
Does any run data leave my Mac?
No. Commands, output, and run history remain on your Mac. No account is required, and optional analytics are off by default.
Is it a subscription?
No. Try everything free for 14 days, then pay $19 once. One license covers one person on every Mac they use, with all v1 updates included and a 30-day, no-questions refund.
