GitLab is a complete platform for software development: it hosts your Git repositories, runs your CI/CD pipelines, tracks your issues, and reviews your code — all in one place. It is the main alternative to GitHub, and many companies choose it because it gives them everything in a single tool. If you want one place for your code, your tests, and your team, GitLab is worth learning.

How does GitLab work? You create a project, push your code to it with Git, and GitLab stores it. You can open merge requests — GitLab's version of pull requests — so your team can review code before it is merged. You can track work with issues and boards, and you can define a CI/CD pipeline in a .gitlab-ci.yml file that runs your tests and deploys your app automatically. And because GitLab can be self-hosted, companies can run it on their own servers, which is a big reason many of them choose it.

GitLab is a good fit for beginners because it brings everything together. You do not need five separate tools — code, issues, and CI are all in one interface, so you learn the whole workflow in one place. The free tier is generous, the documentation is excellent, and the skills transfer directly: if you know GitLab, you will understand GitHub quickly too. Best of all, you can create a project and a pipeline in minutes, with no setup.

How should you learn GitLab well? First, create a free account, make a project, and push a small repository to it, just to feel the flow. Second, learn merge requests: create a branch, change one line, and open a merge request to see how review works. Third, add a .gitlab-ci.yml file that runs your project's tests on every push, because CI is the feature that makes GitLab more than a code host. Fourth, try issues and boards — create three issues and move them across a board — because tracking work is half of what GitLab is for.

Who is GitLab for? Developers who want one platform for code and CI, students learning the full development workflow, and teams that want to self-host their tools. It is especially popular in companies that value having everything under one roof, and in open-source projects that prefer GitLab's model.

But understand its limits too. GitLab is a big platform, and its interface can feel overwhelming at first — focus on repositories and merge requests before you explore the rest. The CI runners on the free tier have limits, so very large projects may need their own runners. And while GitLab is excellent, GitHub is still more popular for open source, so knowing both is better than knowing only one.

To start today, do one small thing: create a GitLab account, make a project, and push a small repository to it. Then open a merge request that changes one line, and merge it yourself. Two small steps are enough to feel how GitLab works — and from there, every DevOps workflow is just a bigger version of the same branch-review-merge idea.
