A missed ping catches a job that stopped. But the sneakiest failure is the job that never ran — the line that was commented out, the schedule that quietly stopped firing, the task you forgot you even had. You can only monitor what you remember is running.

So don't rely on memory: paste your crontab below. Cronping reads each schedule, arms a dead-man's-switch with the right timing derived from the cron expression itself, and hands you back the same crontab with a ping appended to every line. No account, no signup.

Up to 20 lines per import. We never run your commands — we only read the schedule text. Env lines (FOO=bar), comments, and @reboot are skipped.
