Having more than 5 years of experience using GitLab.

We are using GitLab as a version control tool. We have integrated GitLab with Jenkins for Continuous Integration and Deployment. Before GitLab, we were using SVN but the problem with SVN is if someone locked a file in which he/she is working another person has to wait until the lock has been released. GitLab provides a very nice web-based user interface which makes source code organization and maintenance very smooth. The branching concept allows multiple developers to work on the same file simultaneously.

GitLab provides role-based and group-based permission. Admin can set up the access based on their role so that developers can only do the thing that they are allowed to do. E.g. if a developer is not allowed to approve the merge request then the merge button will be disabled for him until the access provides by the admin.

GitLab provides pipelines every time when code is committed respective pipelines run to validate the code. If a pipeline is failing it means the code has some vulnerabilities which need to be corrected immediately. It also provides unit test reports and load performance testing to reduce code validation problems. We can deploy our application in different environments (like staging, test) to ensure code quality.
