Gitlab vs github — both do git, what's actually different?

Head of Product

The "both do git" framing is accurate but undersells how different the two platforms are in terms of scope and philosophy, and the right choice between them depends more on what kind of engineering organization you're building than on which has better git functionality. Git is the underlying version control system, and both GitHub and GitLab use it as the foundation. Where they differ is in how far each platform extends beyond repository hosting. GitHub historically focused on being the best place to host code and collaborate on it, with a strong ecosystem built around pull requests, code review, and open-source community features. GitLab's founding thesis was different: build an integrated DevOps platform where the entire software delivery lifecycle — from writing code to deploying it to monitoring it in production — happens in one application rather than across a collection of separate tools. That difference in philosophy is visible in what each platform includes by default. GitLab ships with a CI/CD system, container registry, package registry, security scanning tools, release management, infrastructure management features, and a built-in deployment pipeline as part of the core product. GitHub has added many of these capabilities over time (GitHub Actions for CI/CD, GitHub Packages for registry, GitHub Advanced Security for scanning), but its ecosystem is historically more oriented toward integrations with best-of-breed external tools rather than everything being native. GitLab's value proposition is that you can manage the entire workflow without needing to integrate and maintain multiple separate tools. For open-source projects and developer communities, GitHub has a significant network effect advantage. The vast majority of open-source projects live on GitHub, which means contributors, forks, stars, and community discussions are concentrated there. If you're building something open-source or expect external contributors, GitHub's community infrastructure is meaningfully better. For private enterprise software development, particularly in organizations that prioritize security, on-premises or self-hosted deployment, and a single-platform DevSecOps approach, GitLab has historically been stronger. GitLab offers a self-managed deployment option that lets organizations run GitLab on their own infrastructure, which matters in regulated industries or environments with strict data residency requirements. GitHub offers GitHub Enterprise, including a self-hosted server option, but GitLab's self-managed offering has been around longer and tends to have more configuration options. Pricing structure differs as well, and this becomes relevant for larger teams. GitLab's free tier is relatively generous in terms of CI/CD minutes and features compared to some GitHub plan configurations, though the comparison shifts depending on team size and which specific features matter to you. Both platforms have grown their enterprise offerings significantly, so the gap has narrowed from where it stood a few years ago. If your team is already heavily invested in the GitHub ecosystem — using GitHub Actions, GitHub Packages, and integrations with tools that natively support GitHub — switching has real migration cost. If you're building a new engineering organization from scratch and want to minimize the number of vendor relationships for your delivery pipeline, GitLab's integrated approach may simplify your stack.
