Everyone has an opinion on this one. Most of those opinions are wrong...not because they pick the wrong platform, but because they treat it like a competition when it's really just a question of fit.

I used GitHub for everything for a long time. Still do, especially at work. But recently I shifted my home lab over to GitLab, and the reason why is probably the clearest way I can explain the difference between the two.

What They Have in Common

Both platforms are built on Git. Both give you repositories, branching, merge/pull requests, and issue tracking. If you're doing basic version control, either one works fine and the differences won't matter much.

The differences start to matter when you zoom out and ask what else you need your platform to do.

GitHub: Where I Started

GitHub is where the developer community lives. A ton of them, the vast majority of open source projects, and deep integrations with practically every tool in the modern software stack. If you're publishing something meant to be found, used, or contributed to then GitHub is the default answer.

It's also the better choice when you already have opinions about your pipeline. GitHub doesn't try to own your CI/CD story. It plays well with GitHub Actions, Jenkins, ArgoCD, AWX, and everything else. You wire up the tools you want, and GitHub holds the source of truth.

At work, I use it exactly this way. Repos storing Ansible playbooks, AWX pulling from them on a schedule, pushing config changes across a fleet of network devices. GitHub's job is to hold the code and track the changes. Everything else is handled downstream. That setup works well when you already have the downstream tooling in place. At home, I didn't.

GitLab: Where My Home Lab Lives Now

The home lab is a different animal. Clusters of self hosting apps. No enterprise tooling, no team. Just me, some hardware, and a pile of things I want to automate and learn. Standing up a full CI/CD stack just to complement GitHub felt like more overhead than the lab itself was worth.

GitLab solved that. Source control, pipelines, container registry, issue tracking...it's all built in and designed to work as a single system. I didn't have to wire anything together. I just started building.

GitLab also self-hosts cleanly, which matters at home. My lab traffic stays on my infrastructure. Nothing leaves my rack unless I want it to.

The tradeoff is real. More capability in one box means more to configure and learn upfront. But once it's running, everything talks to everything without any extra glue.

GitLab is the right call when:

  • You need an integrated platform without managing separate tools
  • Your environment has self-hosting or private data requirements
  • You want built-in CI/CD without wiring up a separate system
  • You're running solo and want one place for everything

The Honest Take

I'm not leaving GitHub. It's still where my 'soon to be' public work lives and where I collaborate with others. But moving the home lab to GitLab clarified something I'd been fuzzy on for a while...GitHub is a great place to store and share code, and GitLab is a great place to run a pipeline.

They're not really competing. They're just answering different questions. Figure out which question you're asking, and the choice gets a lot easier.
