Git and GitHub are not the same thing, even though their names sound almost identical. Git is a free tool that runs on your own computer and keeps track of every change you make to your files. GitHub is a website that stores your Git projects online so you can share them, back them up and work on them with other people. In short: Git is the tool, GitHub is the place where the tool's work lives online. You can use Git completely on your own without ever touching GitHub, but you cannot really use GitHub without Git doing the actual version tracking underneath.
Beginners mix the two up all the time, and honestly, it is an easy mistake to make. People say "I pushed my code to Git" when they mean GitHub, or "download GitHub" when they mean the Git software. Once you see the split clearly, everything else falls into place: why you install something on your computer, why you also create an account on a website, and why your code can live in both places at once.
What Is Git?
Git is a version control system. The idea is simple: every time you finish a piece of work, you take a snapshot of your project. Later, if something breaks, you can look back through your snapshots, see exactly what changed, and jump back to an earlier version — an "undo" button that remembers your whole project history, not just the last few keystrokes.
Git runs on your own machine and works completely offline — no account, no internet, no permission needed. The official Git website describes it as a free and open source distributed version control system, and you can read that for yourself on git-scm.com. "Distributed" is the key word: every copy of a project carries the full history, so no single computer is the only one holding the truth.
Here is the basic Git workflow, in four commands. First you create a project folder and tell Git to watch it. Then you stage the files you want to snapshot, save the snapshot with a message, and repeat whenever you finish something meaningful:
git init
git add index.html style.css
git commit -m "Add homepage layout"
Notice what did not happen: nothing went to the internet. Those snapshots live on your computer only — if your laptop dies, they die with it. That is exactly the problem GitHub solves.
What Is GitHub?
GitHub is a website that hosts Git projects. When people say "my code is on GitHub", a copy of their Git project lives on GitHub's servers, where anyone with the link (or permission, for private projects) can see it and suggest changes. GitHub adds a collaboration layer on top of Git: a web page per project, bug reports called issues, proposed changes called pull requests, and review tools for teams.
GitHub's own documentation puts it plainly: GitHub is a hosting service for Git, and it adds collaboration features on top. You can read the full explanation on GitHub Docs' page about GitHub and Git. The important detail is that GitHub does not replace Git. When you upload a project to GitHub, Git is still the engine recording every change; GitHub is just the very good garage where you park the project so others can find it.
Think of it this way: Git is the camera that takes snapshots of your work, and GitHub is the photo album website where you upload those snapshots so friends can see and comment on them. The camera works fine without the website; the website has nothing to show without the camera.
GitHub Docs explains the split clearly: Git is the version control tool, GitHub is the hosting and collaboration service built around it.
Git vs GitHub: The Side-by-Side Table
| Feature | Git | GitHub |
|---|---|---|
| What it is | Version control software | A website that hosts Git projects |
| Where it runs | On your own computer | On GitHub's servers, in your browser |
| Needs the internet? | No, works fully offline | Yes, for browsing, sharing and syncing |
| Needs an account? | No | Yes, a free GitHub account |
| Main job | Track changes, snapshots, history | Store, share and collaborate on projects |
| Collaboration | Not built in — you share folders manually | Issues, pull requests, code review, teams |
| Cost | Free and open source | Free for public and private projects |
How They Work Together: A Real Workflow
Here is how a typical project flows between the two. You build a website on your laptop, using Git to snapshot your progress. When you are ready to share or back it up, you create an empty project (a repository) on GitHub, connect your local project to it, and push your snapshots up:
git remote add origin https://github.com/yourname/my-website.git
git push -u origin main
From that moment, two copies exist: one on your computer, one on GitHub. Change a file locally, commit it, and push again to update the online copy. Want the project on another computer? Clone it down, and Git brings the full history with it. That round trip — commit locally, push to GitHub — is the heartbeat of modern development.
If you are still fuzzy on the GitHub side of this story, our earlier explainer What Is GitHub and Why Is It Important walks through accounts, repositories and why every developer ends up with a GitHub profile. Once your code lives on GitHub, the next step is automation: our guide to What Is CI/CD, Explained Simply shows how a push to GitHub can automatically test and deploy your project.
What Works Offline, and What Needs the Internet?
With Git alone, you can initialise a project, stage files, commit snapshots, view your history, create branches and undo mistakes — all without any internet at all. Those are local operations, and they are fast because nothing leaves your machine.
What needs GitHub (or any online host) is everything involving another computer: pushing, pulling, cloning a project onto a new machine, opening a pull request, and browsing code in a browser. If your internet goes down mid-project, your Git history is safe on your laptop — you simply cannot sync until you are back online. That is a genuinely reassuring design.
Common Beginner Mistakes
The first mistake is installing GitHub Desktop (or signing up on github.com) and thinking you have installed Git. GitHub Desktop is a friendly app that uses Git behind the scenes, but the actual Git tool is a separate install from git-scm.com. The second mistake is the opposite: committing everything locally and never pushing, then being surprised when a lost laptop means lost work. Commit early, push often — that little rhythm is the whole safety net.
The third mistake is committing files that should never be in a project: passwords, API keys and huge videos. A .gitignore file tells Git which files to skip — set one up at the start. Finally, do not write commit messages like "fix" or "asdf". Future you will read those messages at 2 a.m. hunting for a bug; "Fix login button on mobile" takes five seconds longer and pays for itself.
Are There Alternatives to GitHub?
Yes — and this is another reason the distinction matters. Because Git is an open standard, other websites can host Git projects too: GitLab and Bitbucket are the best known, and switching hosts mostly means changing the remote address and pushing again; your history comes with you. For a beginner, though, GitHub is the sensible default: it is free, most open-source projects live there, and a GitHub profile doubles as a public portfolio that recruiters really do look at.
Frequently Asked Questions
Do I need GitHub to learn Git?
No. You can learn everything about Git — init, add, commit, branches, history — on your own computer, no account needed. Add GitHub later, to share or back up work.
Is GitHub free?
Yes, for individuals. Public and private repositories are both free, with unlimited collaborators on the free plan. Paid plans exist for larger teams, but a beginner will not need them.
Can I use GitHub without the command line?
Yes. GitHub Desktop gives you buttons for committing, pushing and pulling. But learning the basic commands is worth it — they work everywhere, in every tutorial, and on every server.
What happens if GitHub goes down?
Your local Git copies keep working, because every clone holds the full history. You just cannot sync until GitHub is back. That is the beauty of a distributed system: there is no single point of failure for your code.
Conclusion
Git is the tool that tracks your changes on your own computer. GitHub is the website that hosts those tracked projects online so you can share them, back them up and collaborate. Remember that one sentence and the confusion disappears: tool versus website, local versus online, snapshots versus sharing. Install Git, make a few commits on a practice project, then push it to GitHub — and you will have felt the difference instead of just reading about it.
