What is GitLab? An open source application developed using Ruby on Rail to implement a self-hosted Git project repository that can access public or private projects through a web interface. Ruby on Rail is a framework that makes it easy for you to develop, deploy, and maintain web applications. GitLab has similar functionality to GitHub, being able to browse source code, manage bugs and comments, manage team access to repositories, it is very easy to browse committed versions and provides a file history repository, it provides a code snippet feature that can be easily implemented Code reuse, easy to find when needed in the future

What is GitHub?
It is a hosting platform for open source and private software projects, because it only supports git as the only repository format for hosting, hence the name GitHub.

Same point:
Both are web-based Git repositories. To a large extent, GitLab is imitated by GitHub. They both provide platforms for sharing open source projects, and provide development teams with centralized storage, sharing, publishing and collaborative development projects. A place for cloud storage.

Difference:
1. If GitHub uses a private repository, you need to pay for it. GitLab can build a private free repository on it.
2. GitLab gives development teams more control over their code repositories. Compared to GitHub, it has many features:
(1) Allows to set warehouse permissions for free
(2) Allow users to choose to share part of the code of a project
(3) Allow users to set project access permissions to further improve security
(4) It can be set to obtain the overall improvement progress of the team
(5) Through innersourcing, people who are not within the scope of authority cannot access the resource
