- Version control with Git: The magical "undo" button for your code that tracks every change, with the ability to return to earlier versions at any time.
- The web-based platforms GitHub and GitLab offer user-friendly interfaces for collaboration, shared code usage, and interaction with Git repositories.
- Similarities and differences: Core functions like version control, collaboration tools, and issue tracking.
- The right choice: Consider the type of your project (open-source or private), team size, and workflow requirements.
In the world of software development, Git, GitHub, and GitLab have become indispensable tools. They serve not only as means for version control but also as drivers for collaboration and efficiency improvement in the work process. The shared editing of code, the simultaneous tracking of changes, and the storage of projects are of crucial importance for developers, as they enable seamless reversion to earlier versions when challenges arise. But what exactly lies behind the terms Git, GitHub, and GitLab? In this article, we want to answer these central questions.
Version control with Git
Git is an open-source tool that enables multiple developers to work on a project. The history of changes made is stored in a repository. A repository forms a storage location that manages and stores all files, data, and information of a project in a version control system. You can think of Git as a digital filing cabinet for your code that tracks every change and allows you to return to an earlier version at any time. Git is like an "undo" button for your entire project history.
Use case: A development team is working on a new feature. A bug is accidentally introduced. With Git, they can easily revert to an earlier version of the codebase without losing all progress. The tool also recognizes when two developers are working on the same code simultaneously and offers conflict resolution assistance in such cases.
GitHub vs. GitLab: Hosting your code
GitHub and GitLab are platforms based on the Git version control system, primarily used for version control of software projects. Through GitHub or GitLab, developers can host their Git repositories and collaboratively work on software projects from anywhere. Git serves in this context as the underlying version control technology.
Use case: A marketing team working on a new website design uses GitHub or GitLab to store the website code. This way, changes made by different designers can be tracked and earlier versions can be reverted to when needed. Collaboration is simplified by enabling task assignment and having work reviewed by others through pull requests -- all on the same platform.
Git, GitHub & GitLab - Terms and their meaning
What is a Repository?
A repository is a storage location where all files, history, and metadata of a project are kept. It acts as a central place for collaboration and tracking changes.
What does Branch mean?
A branch is a divergence within a repository that allows developers to work independently on different features or bug fixes without affecting the main code.
What are Pull Requests?
A pull request is a request to project maintainers to merge changes from one branch into the main or target branch. This enables peer review and discussion of the proposed changes before they are merged.
What does DevOps stand for?
DevOps is a practice that aims to improve collaboration between development (Dev) and IT operations (Ops) by using automated processes and tools for software delivery and infrastructure management. It promotes a cultural shift toward faster deployments, continuous integration and continuous delivery (CI/CD), and close collaboration between teams -- in line with process automation.
Similarities between GitHub and GitLab
-
Underlying technology: Both platforms are based on Git for version control. Developers familiar with Git commands can thus seamlessly switch between the two web-based platforms.
-
Core functionalities: Both platforms offer the following features:
- Version control with branching and merging for managing different code versions.
- Collaboration tools like pull requests for reviewing and integrating code.
- Issue tracking for managing bugs, tasks, and feature requests.
- Web-based interface with desktop and mobile app integrations for easy access.
Differences between the two platforms
Both GitLab and GitHub offer features for Git version control and collaboration but are oriented toward slightly different needs. The following explains the differences:
Focus areas of GitHub and GitLab
- As a web-based hosting platform for Git repositories, GitHub is known for its vibrant developer community and open-source friendliness. It offers a user-friendly interface and a large marketplace for developer tools.
- GitLab also positions itself as a web-based hosting platform but focuses on a more comprehensive DevOps approach. It offers features such as "integrated" project management tools, CI/CD pipelines, and wiki functionality -- ideal for cloud and SaaS security in development.
Platform focus
- GitHub: Offers a robust core set of version control and collaboration features, but lacks some integrated project management tools.
- GitLab: Offers a broader range of features, which can reduce the need for external integrations.
Pricing
- GitHub offers a free tier with limited private repositories. Paid plans offer more storage and advanced features.
- GitLab: The free version includes an unlimited number of private repositories but has limitations on the number of collaborators, duration, and CI/CD features. Paid plans offer improved scalability and security.
Docker streamlines CI/CD with Git by containerizing your application. This ensures a consistent environment for development, testing, and deployment. Imagine building your code once and then running it flawlessly anywhere! Git version control tracks changes to your containerized application's code, making rollbacks and version management a breeze.

GitHub or GitLab - Selection criteria
Type of project
- Open-source project or community building: GitHub's focus on community makes it an ideal solution.
- Private codebase with a focus on DevOps: GitLab's comprehensive feature set could be advantageous.
Team size and workflow
- Small teams with simple requirements: Both platforms offer free versions that may be sufficient initially.
- Larger teams with complex workflows can benefit from the project management and CI/CD features offered by GitLab.
Neither platform is inherently "better." The optimal choice depends on the specific project requirements and team workflows. A comparative look at tools for data analysis can be found in our article on choosing the optimal data analysis tool.
