Git is a version-control system that tracks every change to your code, and GitHub is an online service that hosts your Git projects so you can back them up and collaborate with others. Put simply: Git is the tool on your computer; GitHub is the website in the cloud. Here’s what each does and how to start using them.

Key Takeaways

  • Git = version control that records every change and lets you undo or branch safely.
  • GitHub = a cloud platform that hosts Git repositories for backup and collaboration.
  • You can use Git without GitHub, but together they’re the industry standard.
  • Core ideas: repository, commit, branch, pull request.
  • Both are free to start — you only need a computer and an account.

What are Git and GitHub?

Git and GitHub are two of the most important tools in modern software development — and they’re easy to mix up.

Git is software that runs on your computer and records the history of your project as you work.

GitHub is a website that stores Git repositories online, so your work is backed up and teams can collaborate on the same code.

Kevin Stratvert’s beginner tutorial below is a friendly, screen-share walk-through of both.

Git vs GitHub: what’s the key difference?

This is the question every beginner asks, so let’s make it crystal clear.

Git is the tool. It does the version tracking, and it works entirely offline on your machine.

GitHub is a hosting service for Git projects. It adds a website, collaboration features and a place to store your code in the cloud.

Analogy: Git is like a word processor’s “track changes”; GitHub is like a shared drive where everyone’s tracked documents live together.

What is version control?

Version control is a system that records changes to files over time so you can recall any earlier version.

Instead of folders named “final,” “final-v2” and “final-REALLY-final,” you get one clean project with a complete, navigable history.

If something breaks, you can see exactly what changed, when, and by whom — and roll back safely.

Why do developers use Git?

Git solves problems that get painful the moment more than one person — or one version — is involved.

It lets you experiment without fear, because you can always return to a working version. It lets teams work on the same project without overwriting each other.

And it creates an audit trail: every change is attributed and reversible. That safety net is why it’s everywhere.

What is a repository?

A repository (or “repo”) is simply a project tracked by Git.

It contains your files plus a hidden history of every change ever made to them.

A repo can live only on your computer (local) or also on GitHub (remote), where it’s backed up and shareable.

What is a commit?

A commit is a saved snapshot of your project at a point in time.

Each commit has a message describing what changed (“Fix login bug”), so the history reads like a logbook.

Committing often, with clear messages, is one of the best habits a beginner can build.

What is a branch?

A branch is a parallel version of your project where you can work without affecting the main code.

You might create a branch to build a new feature, then merge it back once it’s ready and tested.

Branching is what lets big teams work on many things at once without stepping on each other.

What is a pull request?

A pull request (PR) is a GitHub feature for proposing that your branch be merged into the main project.

It’s where teammates review your changes, discuss them, and approve before the code is merged.

PRs turn version control into a collaboration and quality-check process, not just storage.

The essential Git commands

You’ll get a long way with just a handful of commands.

  • git clone — copy a remote repo to your computer.
  • git add — stage the changes you want to save.
  • git commit — save a snapshot with a message.
  • git push — upload your commits to GitHub.
  • git pull — download others’ changes from GitHub.

Master these five and you’re genuinely productive.

What is GitHub, in more detail?

GitHub is the world’s largest platform for hosting and collaborating on code.

Beyond storing repos, it adds issues for tracking bugs and tasks, pull requests for reviews, and a social layer where developers share and contribute to open-source projects.

For many developers, a GitHub profile doubles as a portfolio.

What are GitHub Actions?

GitHub Actions is GitHub’s built-in automation feature.

It can automatically test your code, build your app, or deploy it whenever you push changes — a beginner-friendly on-ramp to CI/CD.

For heavier automation needs, see our roundup of managed CI/CD platforms.

Are there alternatives to GitHub?

Yes — GitHub is the biggest, but not the only option.

GitLab and Bitbucket are popular alternatives, each with their own strengths in built-in CI/CD and team features.

They all use Git underneath, so the skills transfer. Our developer tools roundup compares options.

How do you get started with Git and GitHub?

Getting going takes three quick steps.

  1. Install Git on your computer (it’s free for every operating system).
  2. Create a free GitHub account.
  3. Create or clone a repository and make your first commit.

Many people start with a GitHub desktop app or their code editor’s built-in Git tools before touching the command line.

A simple Git and GitHub workflow

Here’s the everyday loop once you’re set up.

  1. Make changes to your files.
  2. Stage them (git add) and commit with a message.
  3. Push the commit to GitHub.
  4. Open a pull request if you’re collaborating.
  5. Pull to stay in sync with teammates.

That rhythm becomes second nature within a week.

What is a .gitignore file?

A .gitignore is a small file that tells Git which files to leave out of version control.

You use it to skip things like passwords, large build folders and system junk that shouldn’t be shared.

Setting one up early keeps your repo clean and, importantly, keeps secrets out of it.

Public vs private repositories

On GitHub you choose who can see each repo.

Public repos are visible to everyone — ideal for open-source and portfolios.

Private repos are restricted to you and people you invite. GitHub offers free private repositories, so beginners can keep work-in-progress hidden.

Is Git only for programmers?

No — anyone working with text or files can benefit.

Writers, researchers and teams use Git to track documents, configuration files and even website content with full history.

If you can save a file, you can benefit from version control.

Git, GitHub and deploying your website

Git isn’t just for storing code — it’s increasingly how sites go live.

Many modern hosts let you deploy straight from a GitHub repo, so pushing a commit updates your live site automatically.

If you’re building something to publish, pair it with reliable hosting — our guide on how to start a blog is a friendly first step.

Git, GitHub and AI coding tools

Modern AI coding assistants lean heavily on Git.

Tools that write and edit code work best inside a Git repo, where every change is tracked and reversible — so you can review what the AI did and undo it if needed.

See our beginner’s guide to Claude Code for how that looks in practice.

Common beginner mistakes with Git

  • Committing secrets (passwords, API keys) — use a .gitignore.
  • Vague commit messages like “stuff” that no one can read later.
  • Working only on the main branch instead of using branches for new work.
  • Forgetting to pull before pushing, causing conflicts.
  • Fearing mistakes — Git is designed so almost everything is recoverable.

Is Git and GitHub free?

Yes, you can do a huge amount for free.

Git itself is free and open-source. GitHub’s free plan includes unlimited public and private repositories for individuals, with paid tiers for advanced team features.

For learning and most personal projects, you’ll never hit a paywall.

What is a merge conflict, and how do you handle it?

A merge conflict happens when two people change the same part of a file and Git can’t decide which version wins.

It sounds scary but it’s routine. Git marks the conflicting section and asks you to choose what to keep, then you commit the resolved file.

Conflicts are a normal part of collaboration, not a sign something is broken.

What are cloning and forking?

These two terms trip up beginners, so here’s the difference.

Cloning copies a repository to your computer so you can work on it locally.

Forking (a GitHub feature) makes your own copy of someone else’s repository under your account — the basis of contributing to open-source projects.

Git best practices for beginners

  • Commit often, in small, logical chunks.
  • Write clear commit messages that explain why, not just what.
  • Use branches for new features instead of working on main.
  • Pull before you push to stay in sync.
  • Never commit passwords or secrets — use a .gitignore.

Build these habits early and Git stays tidy as your projects grow.

What is a README, and why does every repo need one?

A README is the front page of your repository, usually the first thing visitors see.

It explains what the project does, how to install it, and how to use it. A good README is the difference between a project people can use and one they ignore.

Writing one is also great practice for documenting your own work clearly.

Can Git help solo developers, not just teams?

Absolutely — Git is just as valuable when you work alone.

It gives you a complete history, a safety net to experiment freely, and off-site backup on GitHub. You can roll back a mistake in seconds.

Even a one-person project benefits from the confidence that nothing is ever truly lost.

GitHub, GitLab or Bitbucket: which should a beginner pick?

For most beginners, GitHub is the easiest first choice.

It has the largest community, the most tutorials, and it’s where most open-source lives, so your skills and profile travel furthest.

GitLab and Bitbucket are excellent too, especially for teams wanting built-in CI/CD — but the Git skills you learn work identically on all three.

What is a Git tag and a release?

A tag marks a specific point in your history — usually a version, like v1.0.

On GitHub you can turn a tag into a “release,” with notes and downloadable files, so users know exactly what changed.

Tags and releases are how projects communicate versions clearly to the people who rely on them.

Frequently Asked Questions

What is the difference between Git and GitHub?

Git is a version-control tool that runs on your computer and tracks changes to your files, even offline. GitHub is an online platform that hosts Git repositories so you can back them up and collaborate. In short, Git is the tool; GitHub is the cloud service built around it.

Do I need GitHub to use Git?

No. Git works entirely on your own computer without any online account. GitHub (or an alternative like GitLab or Bitbucket) adds cloud backup, collaboration and a place to share your code. Many people use Git locally first, then add GitHub when they want to back up or collaborate.

Is GitHub free to use?

Yes. Git is free and open-source, and GitHub’s free plan includes unlimited public and private repositories for individuals. Paid tiers add advanced collaboration and security features, but beginners and most personal projects never need to pay.

What is a commit in Git?

A commit is a saved snapshot of your project at a moment in time, along with a short message describing what changed. Commits build up a complete, navigable history of your work, so you can review past versions or roll back if something breaks.

What is a pull request?

A pull request is a GitHub feature for proposing that changes from one branch be merged into the main project. Teammates review and discuss the changes before approving them, which makes pull requests the heart of collaborative, quality-checked development.

Is Git hard to learn?

The basics are approachable — most people become productive with about five commands (clone, add, commit, push, pull). The more advanced features take time, but you don’t need them to start. Beginner-friendly desktop apps and editor integrations make the first steps even easier.

Can non-programmers use Git and GitHub?

Yes. Anyone who works with files can use Git to track changes with full history — writers, researchers and teams manage documents, notes and website content with it. If you can save a file, you can benefit from version control.

The bottom line

Git and GitHub sound intimidating but rest on a few simple ideas: track changes, save snapshots, branch safely, and collaborate through pull requests.

Learn the core five commands, make your first repo, and the rest builds naturally from there.
