Building Apps
Apps on GitHub extend and improve existing workflows. People can build apps, purchase them from GitHub Marketplace, or browse useful tools and services that integrate with GitHub in Works with GitHub.
Note: GitHub Services will no longer be supported as of October 1, 2018. Please see the blog post for details. You can use the Replacing GitHub Services guide to help you update your services to webhooks.
You can build GitHub Apps and OAuth Apps. For information on choosing a type of app, see "Getting started with building apps" and "Differences between GitHub Apps and OAuth Apps."
