The Problem

As a backend developer, every time I need a scheduled job I go through this repetitive workflow:

  1. Figure out the schedule (e.g. “every Monday at 9 am”).
  2. Google “cron expression syntax”.
  3. Open crontab.guru to verify the expression.
  4. Copy the expression, then look up the Kubernetes CronJob YAML format.
  5. Look up GitHub Actions cron syntax separately.
  6. Repeat the process for Jenkins, Airflow, etc.

This is tedious and error‑prone.

Solution: Hey Cron

Hey Cron lets you type a plain‑English (or Chinese) description of your schedule and instantly generates ready‑to‑use configurations for multiple platforms.

Supported Platforms

  • ⚙️ Kubernetes CronJob
  • 🐙 GitHub Actions
  • 🔧 Jenkins Pipeline
  • 🌊 Apache Airflow
  • 🖥️ Linux crontab
  • 🟢 Node.js (node-cron)
  • 🐍 Python (APScheduler)

Example

Input: every Monday at 9am

Output:

0 9 * * 1
# Kubernetes CronJob
schedule: "0 9 * * 1"
# GitHub Actions
cron: '0 9 * * 1'

…and analogous snippets for the other platforms.

Current Status

Hey Cron is currently in development. I’m validating demand before building the full product.

Call to Action

If this solves a real pain point for you, join the waitlist at heycron.com – I’ll notify you when it launches.

Feedback welcome: Is this useful, or do you handle cron expressions differently?
