So I built <strong>Hey Cron</strong>.</p> <h2> What it does </h2> <p>Type a plain English (or Chinese) description of your schedule, and Hey Cron instantly generates ready-to-use configs for:</p> <ul> <li>⚙️ Kubernetes CronJob</li> <li>🐙 GitHub Actions</li> <li>🔧 Jenkins Pipeline</li> <li>🌊 Apache Airflow</li> <li>🖥️ Linux crontab</li> <li>🟢 Node.js (node-cron)</li> <li>🐍 Python (APScheduler)</li> </ul> <p><strong>Example:</strong></p> <p>Input: "every Monday at 9am"</p> <p>Output:</p> <ul> <li>Cron: <code>0 9 * * 1</code> </li> <li>Kubernetes: <code>schedule: "0 9 * * 1"</code> </li> <li>GitHub Actions: <code>cron: '0 9 * * 1'</code> </li> <li>And more...</li> </ul> <h2> Why not just use ChatGPT? </h2> <p>You can. But Hey Cron is faster for this specific task – no context needed, output is always correctly formatted, and you get all platforms at once.</p> <h2> Status </h2> <p>Currently in development. I'm validating demand before building the full product.</p> <p>If this solves a real pain point for you, join the waitlist at <strong><a href="https://www.heycron.com" rel="noopener noreferrer">heycron.com</a></strong> – I'll notify you when it launches.</p> <p>Would love honest feedback: is this useful, or do you handle cron expressions differently?</p> devops kubernetes webdev opensource
