Launch and Manage Cron Jobs Effortlessly

Over the past year, we’ve noticed that many users have encountered challenges while trying to integrate Cron into their projects. In response, we’ve developed a new open-source project designed to help simplify the process.

The project can be found here: Cron Manager

Notable Benefits and Features

Isolated execution

Each job runs in its own isolated machine, preventing issues such as configuration drift, accumulation of temporary files, or other residual effects that could impact subsequent job executions. This isolation ensures that the outcome of one job does not negatively influence another, maintaining the integrity and reliability of each job.

Centralized Scheduling

Manage all your Cron jobs centrally with a simple JSON configuration. This approach removes the need to embed cron dependencies within each production environment, streamlining setup and modifications. The use of a version-controlled configuration file enhances maintainability and auditability of scheduling changes.

Simplified updates

Machines dedicated to specific Cron jobs are ephemeral and do not require updates. Any modifications to the schedules.json file will automatically be applied the next time the machine is provisioned for a scheduled job. This eliminates the need for ongoing maintenance of job environments, resulting in a more efficient update process.

Enhanced Logs and Monitoring

Operating separate machines for each job greatly simplifies monitoring and auditing. This setup allows for straightforward tracking of the outcomes and logs of individual jobs, facilitating easier debugging and performance analysis.

Why the Standalone App?

While setting up a separate application just to handle a single cron job might seem excessive. There are several compelling reasons why running this within it’s own App can still be beneficial:

Efficiency and Flexibility

The solution is designed to be lightweight and flexible, ensuring that the resource footprint remains minimal. This approach allows for quick adaptations and modifications without significant overhead.

Environment Agnosticism

By rolling this into its own project, we avoid making assumptions about your specific deployment environment. This separation ensures that the cron job manager can operate independently of the various systems it might interact with, enhancing compatibility and ease of integration.

Isolation of Dependencies and Scheduling

Dependencies and scheduling are completely isolated from your production environments. This means there is no need to modify or overload your Dockerfiles or other configuration files, keeping your production environments clean and focused solely on delivering their intended services.

Paving the Way for Future Features

This project also serves as a testing ground for a potential native cron feature. By isolating it in this way, we can experiment and refine the functionality without impacting existing setups and gather insights/feedback that can inform the development of a more integrated solution in the future!


We’re eager to see how this can streamline your Cron job management. Give it a try, share your feedback, and help shape the future of Cron management on Fly!
