How do Git, GitHub, GitLab and Bitbucket compare side by side?
The table below compares Git, GitHub, GitLab and Bitbucket across 10 procurement-relevant dimensions, from what it is through source.
Side-by-side comparison
| Dimension | Git | GitHub, GitLab and Bitbucket |
|---|---|---|
| What it is | A version control system that tracks changes to files (GitHub Docs). | GitHub "builds on Git by hosting your Git projects, called repositories, in the cloud" (GitHub Docs). A GitLab project is where you "work with your team, store your files, and manage your tasks" (GitLab Docs). Bitbucket Cloud documentation walks through cloning a Git repository (Atlassian Support). |
| How history is recorded | Data is treated as "a series of snapshots of a miniature filesystem"; everything is checksummed before storage and referred to by that checksum, using SHA-1 (Pro Git book). | The host stores your Git repositories, so the snapshot and checksum model is Git's own (GitHub Docs). |
| Where it runs | "Most operations in Git need only local files and resources to operate" (Pro Git book). | GitHub hosts repositories in the cloud (GitHub Docs). GitLab also describes a self-managed option: an instance "managed by you" with "full control of your data and infrastructure" (GitLab). |
| Proposing and reviewing changes | Git records the changes; review happens on a host. | GitHub: pull requests are "proposals to merge code changes into a project". GitLab: merge requests are a central place to review code, where a reviewer can request changes or approve. Bitbucket Cloud documents pull requests as well. |
| Naming to watch for | Not applicable. | Pull request on GitHub and Bitbucket; merge request on GitLab. |
| Planning and tracking work | Not part of the version control tool itself. | GitHub: create issues and track project work. GitLab: track issues and tasks. |
| Automation (CI/CD) | Not part of the version control tool itself. | GitHub: automate workflows such as CI/CD, testing and deployments. GitLab: CI/CD pipelines to test and deploy. Bitbucket: build, test and deploy with Pipelines. |
| Other integrations named in the docs | None named. | Bitbucket Cloud documentation covers integrating Bitbucket and Jira. |
| When to pick each | Use Git for every project: the hosts above are built around Git repositories, and Git works on local files. | GitHub or GitLab when you want issues, review and CI/CD in one hosted place; GitLab when a self-managed instance is required; Bitbucket when your team already uses Jira. |

Common questions
Common questions about Git vs GitHub, GitLab and Bitbucket
Is GitHub the same as Git?
+
No. Git is the version control system that tracks changes to files. GitHub is based on Git and hosts Git repositories in the cloud, adding features such as issues and pull requests.
What is the difference between GitHub and GitLab?
+
Both host Git projects and offer issue tracking, review and CI/CD. The review object is called a pull request on GitHub and a merge request on GitLab, and GitLab documents a self-managed option that you run yourself.
Does Bitbucket use Git?
+
Bitbucket Cloud's getting-started documentation covers Git commands and cloning a Git repository, and it adds pull requests, Pipelines and a Jira integration.
