cronexpr - Cron expression parser in Go language (golang)

•    Go

Given a cron expression and a time stamp, you can get the next time stamp which satisfies the cron expression. In another project, I decided to use cron expression syntax to encode scheduling information. Thus this standalone library to parse and apply time stamps to cron expressions.

CRON for PHP: Calculate the next or previous run date and determine if a CRON expression is due

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.

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.

sidekiq-cron - Scheduler / Cron for Sidekiq jobs

•    Ruby

A scheduling add-on for Sidekiq. Runs a thread alongside Sidekiq workers to schedule jobs at specified times (using cron notation * * * * * parsed by Rufus-Scheduler, more about cron notation.

django-cron - Write cron business logic as a Python class and let this app do the rest! It enables Django projects to schedule cron tasks, tracks their success / failures, manages contention (via a cache) etc

•    Python

Django-cron lets you run Django/Python code on a recurring basis providing basic plumbing to track and execute tasks. The 2 most common ways in which most people go about this is either writing custom python scripts or a management command per cron (leads to too many management commands!). Along with that some mechanism to track success, failure etc. is also usually necesary. This app solves both issues to a reasonable extent. This is by no means a replacement for queues like Celery ( http://celeryproject.org/ ) etc.

healthchecks - A Cron Monitoring Tool written in Python & Django

•    Python

healthchecks is a watchdog for your cron jobs. It's a web server that listens for pings from your cron jobs, plus a web interface. These are instructions for setting up healthchecks Django app in development environment.

SINC (SINC Is Not Cron)

•    C++

SINC (SINC Is Not Cron) is designed to be a free scheduling utility application for the Win32 environment. Based on Vixie Cron, SINC reads cron-like sinctab files and executes pre-scheduled jobs at the correct time.

meteor-synced-cron - A simple cron system for Meteor

•    Javascript

Since I'm no longer actively developing an app that uses synced-cron, I've lost touch with the codebase and the project. I'm looking for folks to take over development and maintenance, please raise your hand if you're interested via this issue. A simple cron system for Meteor. It supports syncronizing jobs between multiple processes. In other words, if you add a job that runs every hour and your deployment consists of multiple app servers, only one of the app servers will execute the job each time (whichever tries first).

jobber - An alternative to cron, with sophisticated status-reporting and error-handling

•    Go

A replacement for cron, with sophisticated status-reporting and error-handling. Jobber is a lightweight utility for Unix-like systems that can run arbitrary commands, or "jobs", according to a schedule. It is meant to be a replacement for the classic Unix utility cron.

Shuttle Core

Shuttle Core is a project that contains cross-cutting libraries for use in .net software development.

later - A javascript library for defining recurring schedules and calculating future (or past) occurrences for them

•    HTML

Later is a library for describing recurring schedules and calculating their future occurrences. It supports a very flexible schedule definition including support for composite schedules and schedule exceptions. Create new schedules manually, via Cron expression, via text expressions, or using a fully chainable API. For more information on SemVer, please visit http://semver.org/.

Cron Script Manager for Windows

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.

cron-parser - Node.js library for parsing crontab instructions

•    Javascript

Node.js library for parsing crontab instructions. It includes support for timezones and DST transitions. Supports mixed use of ranges and range increments (L, W and # characters are not supported currently). See tests for examples.

minicron - 👨🏻‍💻 Monitor your cron jobs

•    Ruby

minicron makes it simple to monitor your cron jobs and ensure they are running both correctly and on schedule. Latest stable release in 0.9.7 tag but 0.9.x is not being actively developed/supported. This branch is under active development for 1.0.0.

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.
