cronsun is a distributed, fault-tolerant cron-style job scheduler written in Go, designed to manage scheduled jobs across many machines with a web management panel. It uses etcd for coordination and MongoDB for storing job definitions and execution results, and has been battle-tested in production on hundreds of servers.

Use cases

  • manage cron jobs across hundreds of servers from one web panel
  • run scheduled tasks with high availability and failover
  • replace scattered crontab files on many machines with centralized job management
  • get email alerts when scheduled jobs fail
  • restrict which commands scheduled jobs are allowed to execute

When to choose

  • you need to schedule and monitor cron jobs on many machines with a central UI
  • you want fault-tolerant job execution where node failures don't lose scheduled tasks
  • you prefer a lightweight cron-focused tool over heavyweight workflow engines like Airflow

When to avoid

  • you need complex DAG-based workflow orchestration with dependencies between tasks
  • you want a fully stable tagged release - master branch is explicitly not stable
  • you can't operate etcd and MongoDB as dependencies
  • you need strong authentication - built-in auth is simple with default admin credentials
