Will you know if a every day at midnight run is skipped?
Knowing when 0 0 * * * should fire is only half of it. The failure that hurts is the silent one — the box was asleep, the trigger broke, the token expired, and nobody noticed. Cronpulse is a free dead-man's-switch: your job pings a URL each time it runs on this schedule, and if a ping goes missing, we alert you by email, Discord, Slack, or webhook.
