Version Control Software for Beginners: Git vs SVN

Version control software (also called source control or a version control system, VCS) records every change to your code so you can see who changed what, undo mistakes, and work on the same files with other people without overwriting each other. The open source standard today is Git; Apache Subversion (SVN) is the main older alternative and is still maintained. If you are starting from zero in 2026, learn Git first.

This guide explains source control in plain terms, compares the open source tools you will actually run into, and walks through a first Git project with commands you can copy.

What source control (version control) actually does

A version control system keeps a history of snapshots of a project. Each snapshot (a commit in Git, a revision in SVN) stores:

• the changed files,
• who made the change and when,
• a message explaining why.

With that history you can:

1. Go back: restore a file or the whole project to any earlier state.
2. Compare: see the exact lines that changed between two versions (git diff).
3. Work in parallel: develop a feature on a separate branch, then merge it back.
4. Find the cause of bugs: see which commit introduced a line (git blame) or binary-search history for the bad commit (git bisect).
5. Collaborate: share changes through a server such as GitHub, GitLab, or a self-hosted Gitea instance.

"Source control", "version control", "revision control" and "source code management (SCM)" all mean the same thing in practice.

Centralized vs distributed version control systems

There are two main types of version control system:

	Centralized (e.g. SVN)	Distributed (e.g. Git, Mercurial)
Where history lives	On one central server	Every clone has the full history
Working offline	Limited: commits need the server	Full: commit, branch, view log offline
Branching	Branches are directory copies on the server	Cheap, local, used constantly
Access control	Fine-grained, per-directory paths	Usually per repository
Large binary files	Handles them well, partial checkouts	Needs Git LFS or partial clone

A third, older type is local version control (tools like RCS that track single files on one machine). You will rarely meet it now.

Open source version control tools compared

Examples of version control systems you can use for free, as of October 2026:

Tool	Type	License	Latest release	Good fit
Git	Distributed	GPLv2	2.56.0 (Sep 28, 2026)	Almost everything; the default for open source and jobs
Apache Subversion (SVN)	Centralized	Apache 2.0	1.15.0 (Oct 8, 2026)	Existing SVN repos, large binaries, strict path-based permissions
Mercurial	Distributed	GPLv2+	7.x	Teams that prefer a simpler command set than Git
Fossil	Distributed	BSD	Ongoing	Small projects that want wiki, tickets and VCS in one file

Commercial version control software also exists, such as Perforce P4 (formerly Helix Core), which is common in game studios with huge binary assets, and Azure DevOps, which offers both Git and the older centralized TFVC. Neither is open source.

Does anyone still use SVN?

Yes. Subversion is actively maintained (1.15.0 shipped on October 8, 2026, per the project's news page), and it stays in use at companies with long-lived repositories, in some game and hardware teams, and where admins need per-folder permissions. But almost all new open source projects and most job listings use Git, and GitHub, GitLab and Bitbucket are all Git hosts.

Git vs SVN in one paragraph

With SVN you svn checkout a working copy from the server, edit, and svn commit straight to the server; every commit is immediately shared. With Git you git clone the entire repository, make as many local commits as you like, and git push when ready. Git makes branching and offline work trivial; SVN makes the central server the single source of truth and is simpler to reason about for linear workflows.

Your first Git repository, step by step

These steps work on macOS, Windows and Linux.

1. Install Git. Download it from git-scm.com/downloads. On macOS, xcode-select --install or brew install git also works. Check it:

   git --version
   

2. Set your identity (once per machine). This name and email go into every commit:

   git config --global user.name "Ada Lovelace"
   git config --global user.email "ada@example.com"
   git config --global init.defaultBranch main
   

   The last line matters: until Git 3.0, an unconfigured git init still names the first branch master. Git 2.52's release notes announced that Git 3.0 will switch the default to main, which GitHub and GitLab already use.

3. Create a repository in a project folder:

   mkdir hello-git && cd hello-git
   git init
   echo "# Hello Git" > README.md
   

4. Stage and commit. git add chooses what goes into the next snapshot; git commit saves it:

   git status
   git add README.md
   git commit -m "Add README"
   git log --oneline
   

5. Ignore files you don't want tracked, like dependencies and secrets. Create .gitignore:

   node_modules/
   .env
   dist/
   

   Never commit API keys or passwords. If one slips into a commit, rotate the key; deleting the file later does not remove it from history.

6. Work on a branch, then merge it:

   git switch -c add-greeting
   echo "Hello, world" > hello.txt
   git add hello.txt
   git commit -m "Add greeting"
   git switch main
   git merge add-greeting
   git branch -d add-greeting
   

   git switch (available since Git 2.23) is the clearer modern replacement for using git checkout to change branches.

7. Push to a remote. Create an empty repository on GitHub (or GitLab, or your own Gitea or Forgejo server), then:

   git remote add origin https://github.com/your-name/hello-git.git
   git push -u origin main
   

   GitHub no longer accepts account passwords for Git over HTTPS; use a personal access token, SSH key or GitHub CLI instead.

Undoing mistakes safely

You want to	Command
Discard uncommitted changes to one file	git restore file.txt
Unstage a file (keep the edits)	git restore --staged file.txt
Fix the last commit message (not yet pushed)	git commit --amend
Undo a pushed commit without rewriting history	git revert <commit>
See what you did recently, including "lost" commits	git reflog

Prefer git revert over git reset --hard on shared branches: revert adds a new commit, so teammates' history stays intact.

The same basics in SVN

If your team uses Subversion, the daily loop looks like this (SVN book):

svn checkout https://svn.example.com/repo/trunk my-project
cd my-project
svn update                 # get teammates' changes
svn status                 # what changed locally
svn add newfile.txt
svn commit -m "Add newfile"
svn log -l 5

Branches in SVN are server-side copies, usually under branches/: svn copy ^/trunk ^/branches/feature-x -m "Create branch". If you are migrating to Git, git svn can import an SVN history, though large repos with complex branch layouts usually need cleanup.

Version control best practices for beginners

• Commit small, focused changes with messages that say why, not just what ("Fix login redirect loop on Safari" beats "fix").
• Pull or fetch before you start work to reduce conflicts.
• Use branches for every feature or fix and merge through pull requests so someone reviews the code.
• Don't store large binaries in plain Git. Use Git LFS for assets like videos or design files.
• Read the diff before every commit with git diff --staged.

When you're comfortable with the basics, most IDEs have Git built in; see our guide to setting up version control in GoLand. Students can get free GitHub Pro and other tools through the GitHub Student Developer Pack, and more free developer credits are listed on DevHunt perks.

Honest limitations

• Git's learning curve is real: staging, rebasing and detached HEAD confuse everyone at first. Learn status, add, commit, switch, merge, pull, push before anything else.
• Git is weak with very large binary files and huge monorepos without extra tooling (LFS, sparse checkout, partial clone).
• Version control is not a backup of your whole machine, and it does not protect secrets once committed.

FAQ

What is an example of a version control system?

Git is the most common example. Others are Apache Subversion (SVN), Mercurial and Fossil (all open source), and commercial tools such as Perforce P4 and Azure DevOps TFVC. GitHub and GitLab are hosting services built around Git, not version control systems themselves.

Is Git the same as GitHub?

No. Git is the open source version control software that runs on your computer. GitHub is a website that hosts Git repositories and adds pull requests, issues and CI. You can use Git with GitLab, Bitbucket, a self-hosted server, or no server at all.

Is SVN open source?

Yes. Apache Subversion is free, open source software under the Apache License 2.0, maintained by the Apache Software Foundation.

Which version control software should a beginner learn?

Git. It is what open source projects, most employers, and every major code host use. Learn SVN only if a job or an existing project requires it; the core ideas (commits, history, branches, merges) transfer.

Is version control only for code?

No. It works for any text files: documentation, configuration, infrastructure-as-code, even writing. It works less well for large binary files like video, where tools such as Git LFS or Perforce are a better fit.
