Stale - Probot Plug-in - A useful bot that will close unrelated issues and pull requests after a designated period of time.

Todo - Probot plugin - Allows you to easily create new GitHub issues by simply adding keywords in your source code:

Release Drafter - Created by Tim Lucas

You can use it to, post comments the repository's issues page, filter issues, and save it as a bookmark on your dashboard. You can also use it to "Star" (Favorite) a repository, fork and follow users.

WIP - Created by Gregor Martynus


WIP - An application designed to prevent accidentally merging files under development.

WIP responds to keywords (e.g. - "WIP", "do not merge", etc.) in the title of a pull request. If a keyword is found, it will "Uncheck" the file so it won't be checked in.

ImgBot - Created by Dan Butvinik


ImgBot - Crawls all the image files in the repository and sends a pull request after performing a lossless compression.
For lossless compression, the file size is the same and the quality is maintained.

typot - Created by Takahiro Kubo


typot - A bot that detects typo in a pull request.

backlog - Created by Abi Noda


backlog - A plugin for Slack that posts a pull request reminder to Slack.

Jenkins - Created by Jenkins


Jenkins is a CI (Continuous Integration) tool known for its high versatility. Unlike CircleCI (mentioned later in this list), it can be installed on a server. After Installation and Configuration is completed, you can use the web interface to do many useful things:

  • Automate Build Processes
  • Run Tests
  • Deploy Artifacts to Servers
  • And just about any other tasks you're sick of doing manually!

CircleCI - Created by Circle Internet Services, Inc.,


CircleCI - Unlike Jenkins, Circle CI is a cloud service and comes with minimal setup and no need to host on a private server -- more than two containers will come with a monthly fee.

You can easily establish a link to your GitHub projects and configuration can be easily managed in a simple YAML file (circle.yml) , so the operational hurdle is not high.

Travis CI - Created by Travis CI


Travis CI - Similar to Circle CI, Travis CI is also a cloud based CI service. Travis CI will provide services free of charge for all open source projects. However, there are drawbacks such as not being able to connect SSH to the container and no remote debugging.

Redmine - Created by Redmine

Redmine - An information sharing and communication tool. Redmine provides easy file management, wiki functions, and offers the ability to share information.

You can register tasks such as bug resolutions to members as tickets, and check and share progress.

Wrike - - Created by Wrike, Inc.


Wrike - Although similar in many ways to Redmine, Wrike is a very powerful tool which can be used to view projects in chronological order (e.g. - view tasks sorted by Date/Time) and incorporate Gantt charts.

Additionally, you can add subtasks to tasks, and can track time for each item or task.


Asana - Created by Asana


Asana - A tool that can be used by up to 15 people for FREE.

Unfortunately, you cannot manage man-hours or use Gantt chart like you can with Wrike, however, chat is available within tasks, allowing for much easier communication with you team.

Flow - - Created by Flow


Flow - A project management tool with many simplarities to the previously mentioned items, but with Flow you can set routine tasks and manipulate tasks on the calendar. You can also save a project as a template, so it can be a useful tool for those who launch many similar projects.
