Rundeck - Job Scheduler and Runbook Automation

•    Groovy

---

Rundeck is an open source automation service with a web console, command line tools and a WebAPI. It lets you easily run automation tasks across a set of nodes. It can schedule a job, more secure replacement of cron. It provides support for runbook automation where it can execute common set of reusable procedures.

evQueue - Job scheduler and queueing engine

•    C++

---

evQueue is an open source job scheduler and queueing engine. It features an event-driven C++ engine and a PHP / MySQL web control interface which provides tasks monitoring and creation. It provides both simple task execution and complex task chaining (workflow) using an easy to use drag & drop web interface. Workflow description includes output linking to input, conditions, loops... Queues management provides an easy way for task parallelization and resource control.

Job Scheduler

•    Java

---

The Job Scheduler is used for automation - for example, process automation using the free database systems MySQL, PostgreSQL or Firebird or using SQL Server, Oracle or DB2. You can use the Job Scheduler to launch executable files and shell scripts and to run database procedures automatically. Jobs are configurable as Web Services providing interoperability with enterprise applications.

crono - A time-based background job scheduler daemon (just like Cron) for Rails

•    Ruby

---

Crono is a time-based background job scheduler daemon (just like Cron) for Ruby on Rails. Currently, there is no such thing as Ruby Cron for Rails. Well, there's Whenever but it works on top of Unix Cron, so you can't manage it from Ruby. Crono is pure Ruby. It doesn't use Unix Cron and other platform-dependent things. So you can use it on all platforms supported by Ruby. It persists job states to your database using Active Record. You have full control of jobs performing process. It's Ruby, so you can understand and modify it to fit your needs.

node-cron - Cron for NodeJS.

•    Javascript

---

Cron is a tool that allows you to execute something on a schedule. This is typically done using the cron syntax. We allow you to execute a function whenever your scheduled job triggers. We also allow you to execute a job external to the javascript process using child_process. Additionally, this library goes beyond the basic cron syntax and allows you to supply a Date object. This will be used as the trigger for your callback. Cron syntax is still an acceptable CronTime format. Although the Cron patterns supported here extend on the standard Unix format to support seconds digits, leaving it off will default to 0 and match the Unix behavior. Because we can't magically know what you are doing to expose an issue, it is best if you provide a snippet of code. This snippet need not include your secret sauce, but it must replicate the issue you are describing. The issues that get closed without resolution tend to be the ones without code examples. Thanks.

chronos - Fault tolerant job scheduler for Mesos which handles dependencies and ISO8601 based schedules

•    Scala

---

Chronos is a replacement for cron. It is a distributed and fault-tolerant scheduler that runs on top of Apache Mesos that can be used for job orchestration. It supports custom Mesos executors as well as the default command executor. Thus by default, Chronos executes sh (on most systems bash) scripts. Chronos can be used to interact with systems such as Hadoop (incl. EMR), even if the Mesos agents on which execution happens do not have Hadoop installed. Included wrapper scripts allow transfering files and executing them on a remote machine in the background and using asynchronous callbacks to notify Chronos of job completion or failures. Chronos is also natively able to schedule jobs that run inside Docker containers.

ofelia - A docker job scheduler (aka. crontab for docker)

•    Go

---

Ofelia is a modern and low footprint job scheduler for docker environments, built on Go. Ofelia aims to be a replacement for the old fashioned cron. It has been a long time since cron was released, actually more than 28 years. The world has changed a lot and especially since the Docker revolution. Vixie's cron works great but it's not extensible and it's hard to debug when something goes wrong.

dagobah - Simple DAG-based job scheduler in Python

•    CSS

---

Dagobah is a simple dependency-based job scheduler written in Python. Dagobah allows you to schedule periodic jobs using Cron syntax. Each job then kicks off a series of tasks (subprocesses) in an order defined by a dependency graph you can easily draw with click-and-drag in the web interface. Dagobah lets you retry individual tasks from failure, sends you helpful email reports on job completion and failure, keeps track of your tasks' stdout and stderr, and persists its information in various backends so you don't have to worry about losing your data.

Bee Queue - A simple, fast, robust job/task queue for Node.js, backed by Redis

•    Javascript

---

A simple, fast, robust job/task queue for Node.js, backed by Redis.Bee-Queue is meant to power a distributed worker pool and was built with short, real-time jobs in mind. A web server can enqueue a job, wait for a worker process to complete it, and return its results within an HTTP request. Scaling is as simple as running more workers.
