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

Deploy in 30 Seconds

Write code, set schedule, click deploy. Zero server configuration or DevOps needed.

3 Clicks to Deploy

Login → Create Job → Paste Code → Save. Running in under 30 seconds.

Perfect for Your Scripts

No repo needed. Great for API monitoring, data sync, email alerts, or any recurring task.

✨ 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);

Built by Developers, for Developers
