A web-based tool for DevOps lifecycle management and source code hosing. GitLab, much like GitHub use the open-source technology Git for repository management and code reversion. On top of that GitLab provide extra services like issue-tracking, wiki and CI/CD pipelines for code deployment. The main difference between GitLab and GitHub is that GitLab is open-source and the whole platform can be self-hosted on your own server. GitLab also provides the same hosted repository solutions provided by GitHub.

With Bitbucket developers and teams can collaborate better on software projects. BitBucket is a web-based version control repository hosting service owned by Atlassian.

With Subversion teams of developers can maintain the current and historical versions of a project source code with ease.

Git is a free and open source distributed version-control system for tracking changes in source code during software development. The tool is created by Linus Torvalds, the creator of Linux, and is used by virtually every software project today. With Git, developer can track changes in any sets of files in a project and coordinate the team to develop in a non-linear workflow to achieve maximum efficiency.

Trac is an enhanced open source, wiki and issue tracking system for software development projects. With Trac, developers and teams can manage their projects with ease and write great software in the process. Trac provides bug tracking system that ca be used by organizations building open source or proprietary software. The system impose as little as possible on team's established development process and policies, while integrating seamlessly with version control systems including Subversion and Git.
