Why Developers Are Choosing CronJS Over Traditional Server Setup
Stop wrestling infrastructure and annoying debugging. Start shipping automation in seconds.
Traditional Server Setup
Server Management Overhead
Hours spent on server setup, monitoring, and maintenance instead of building features.
Reliability Concerns
Jobs fail silently, servers crash unexpectedly, and debugging over ssh is time-consuming.
Infrastructure Costs
VPS costs, monitoring tools, backup solutions, and your valuable development time.
CronJS Cloud Platform

✨ Real Example: How I Use CronJS
Weekly User Engagement for SHOTMETRICS AI
The Problem: Users upload datasets but forget to come back and add more training data.
My Solution: A weekly cron job that queries PostgreSQL to find users who uploaded data but haven't logged in since. Then sends them a personalized reminder email.
Time to Deploy: Literally 2 minutes. Just JavaScript connecting to my database.
// Weekly check - runs every Sunday at 9 AM
const inactiveUsers = await getUsersWithDataButNoRecentLogin();
await sendEngagementEmails(inactiveUsers);
