## What it is
Jiacrontab is a self-hosted, web-based scheduled task management tool written in Go, consisting of an admin web UI (jiacrontab_admin) and a scheduler daemon (jiacrontabd) communicating over RPC. It supports cron jobs with concurrency limits, timeouts, cross-server script dependencies, failure notifications, and long-running daemon process supervision.

## Use cases
- manage cron jobs through a web interface
- schedule scripts across multiple servers with dependencies
- restart long-running daemon scripts automatically if they exit
- get notified when a scheduled script fails
- limit concurrent executions of the same job
- replace system crontab with a centralized task scheduler

## When to choose
- you need a web UI to manage scheduled jobs on multiple machines
- you want job dependencies, timeouts, and concurrency control beyond plain crontab
- you need daemon process supervision for resident scripts
- you prefer a lightweight self-hosted scheduler in Go

## When to avoid
- you need to push jobs to tens of thousands of instances - the author recommends Jiascheduler instead
- you only need simple single-machine cron - system crontab is simpler
- you require a fully distributed, HA scheduler like Airflow or Temporal
