Standard Unix cron only supports minute-level scheduling. frequent-cron fills the gap by running commands at millisecond precision -- ideal for:
- Polling queues or APIs multiple times per second
- Health checks at sub-second intervals
- High-frequency data collection
- Any task that needs to run more often than once per minute
frequent-cron has been production-stable for 15+ years. Starting with v0.3.0, it also works as a service manager -- register named services, start/stop them, view logs, and let the OS supervise them natively via systemd, launchd, rc.d, or the Windows Service Control Manager.
