Production job scheduling is a different discipline from writing a script: you need persistence across restarts, overlap prevention, retry semantics, and a way to see what ran. Three libraries dominate Node.js scheduling — <strong>node-cron</strong>, <strong>Bree</strong>, and <strong>Agenda</strong> — and they solve very different problems under the same label.</p>
