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
