In January 2020, GitHub reported that they have more than 40 million users[8] and more than 100 million repositories[9] (including at least 28 million public repositories).[10] Therefore, it is recognized as the largest host of source code in the world.[11]

Organizational users


Currently, there are many individual GitHub users. On the other hand, there are also organizational users such as educational institutions[12][13][14] and companies. The following companies are using GitHub to distribute open source projects:

Desktop version


GitHub was made for users who want to save their programs on their web browsers. But there is also a desktop version known as GitHub Desktop.[23]

GitHub Pages


All GitHub users can create websites with the domain. This service is known as GitHub Pages.[24] The development history of the HTML code will be recorded with Git.

Similar services


Today, there are several GitHub like services for developers. Some of them use Git but have different interface with unique web-design. One of the most famous GitHub rival is GitLab.[25][26] This is also based on Git. Users can export their programs on GitHub to GitLab.
