Version Control Software for Beginners: Git vs SVN
Version control software (also called source control, source code version 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 is Git: 93.87% of developers in the last Stack Overflow Developer Survey to ask the question said they use it. Apache Subversion (SVN) is the main older alternative and is still maintained. If you are starting from zero in November 2026, learn Git first, host it on GitHub, GitLab or Codeberg, and pick up the others only when a project needs them.
This guide explains source control in plain terms, compares the open source version control tools and source control software you will actually run into (Git, SVN, Mercurial, Fossil, Jujutsu and Pijul), walks through a first Git project with commands you can copy, and ends with a cheat sheet and the mistakes almost every beginner makes.
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, a changeset in Mercurial, a check-in in Fossil) stores:
- the changed files,
- who made the change and when,
- a message explaining why.
With that history you can:
- Go back: restore a file or the whole project to any earlier state.
- Compare: see the exact lines that changed between two versions (
git diff). For a quick look at two pasted snippets, DevHunt's diff checker does the same in your browser. - Work in parallel: develop a feature on a separate branch, then merge it back.
- Find the cause of bugs: see which commit introduced a line (
git blame) or binary-search history for the bad commit (git bisect). - Collaborate: share changes through a server such as GitHub, GitLab, or a self-hosted Gitea instance.
"Source control", "version control", "revision control" (you will also see "source revision control") and "source code management (SCM)" all mean the same thing in practice. Source code version management is the same idea applied specifically to code; the tools also work for docs, config files and anything else stored as text.
How a version control system works under the hood
You don't need internals to use Git, but one picture helps everything else make sense. Git has three places your work can be:
| Area | What lives there | Command that moves work forward |
|---|---|---|
| Working directory | The files you are editing right now | git add copies changes to the staging area |
| Staging area (index) | The exact set of changes for the next commit | git commit saves them as a snapshot |
Repository (.git folder) |
Every commit ever made, plus branches and tags | git push sends commits to a remote server |
Every commit points to its parent, so history is a chain (or, after merges, a graph). A branch is just a movable label pointing at one commit, which is why Git branches are so cheap to create. SVN and Fossil skip the staging area: you edit files, then commit directly. Jujutsu goes further and treats your working copy itself as a commit that updates automatically.
Centralized vs distributed version control systems
There are three types of version control system. The two you will meet are centralized and distributed:
| Centralized (e.g. SVN) | Distributed (e.g. Git, Mercurial, Fossil) | |
|---|---|---|
| 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 |
| File locking | Built in (svn lock) |
Only through add-ons such as Git LFS locking |
A third, older type is local version control: tools like RCS that track single files on one machine with no server at all. Local source control is still what you get if you run Git on your laptop and never add a remote, which is a perfectly good way to start. The difference from RCS is that Git can later be pushed anywhere without changing how you work.
Open source version control tools compared
Version control systems examples you can use for free, as of November 2026. These six open source control systems (open source VCS, for short) are the source control examples you will run into most. Versions and dates come from each project's own release page, linked in the table.
| Tool | Type | License | Latest release | Learning curve | Good fit |
|---|---|---|---|---|---|
| Git | Distributed | GPLv2 | 2.56.0 (Sep 28, 2026) | Medium | Almost everything; the default for open source and jobs |
| Apache Subversion (SVN) | Centralized | Apache 2.0 | 1.15.0 (Oct 8, 2026) | Low | Existing SVN repos, large binaries, strict path-based permissions |
| Mercurial | Distributed | GPLv2 or later | 7.2.4 (Aug 11, 2026) | Low to medium | Teams that prefer a simpler command set than Git |
| Fossil | Distributed | BSD 2-clause | 2.28 (Mar 11, 2026) | Low | Small projects that want wiki, tickets and VCS in one file |
| Jujutsu (jj) | Distributed, Git-compatible | Apache 2.0 | 0.46.0 (Oct 7, 2026) | Medium | Git users who want easier history editing and a real undo |
| Pijul | Distributed, patch-based | GPLv2 or later | 1.0.0-beta.26 (Oct 30, 2026) | Medium | Experimenting with patch theory and conflict-free merges |
Multiple answers allowed. 2022 is the most recent year the survey asked this question. Source: Stack Overflow Developer Survey 2022, 71,379 responses
Among professional developers the Git share was even higher, 96.65% (53,374 responses), while 17.18% of people learning to code said they did not use any version control yet. That second number is the gap this guide is for.
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 (Visual Studio supports both out of the box). Neither is open source. Older open source systems you may find in legacy projects include CVS and Bazaar; Bazaar's community fork, Breezy, is still released (3.3.24 in October 2026) and can work with both Bazaar and Git repositories.
Git: the default for almost everyone
Git was started by Linus Torvalds in April 2005 for Linux kernel development, after the kernel lost free access to the proprietary BitKeeper tool (Pro Git, "A Short History of Git"). Its design goals were speed, cheap branching and handling very large projects, and it still shows: creating a branch takes milliseconds, and every clone is a full backup.
What to know as a beginner:
- Pros: everywhere (every major host, IDE and CI system speaks Git), huge amount of learning material, works offline, free.
- Cons: the command set grew over 20 years and is inconsistent in places; the staging area and rebasing confuse newcomers.
- Coming in Git 3.0: Git's breaking changes plan lists
mainas the default branch name for new repositories, SHA-256 as the default hash for new repositories, and the faster "reftable" format for references. You don't need to do anything today.
Apache Subversion (SVN): the centralized classic
Subversion was founded in 2000 by CollabNet and is now an Apache Software Foundation project that describes itself as "enterprise-class centralized version control" (subversion.apache.org). There is one central repository; you check out a working copy, and every commit goes straight to the server. That makes SVN source control easy to explain: there is one history, one latest revision number, and no pushing or pulling.
- Pros: simple mental model, per-directory permissions, file locking for binary assets, you can check out just one subfolder of a huge repository.
- Cons: no offline commits, branches are heavier, fewer modern hosting options, a shrinking pool of developers who know it.
Mercurial: Git's friendlier sibling
Mercurial (command hg) solves the same problem with a smaller, more consistent command set. It is free software under the GNU GPL version 2 or later (mercurial-scm.org/about). Mercurial is still actively developed: 7.0 shipped on March 25, 2025, 7.1 on August 4, 2025 and 7.2 on January 29, 2026, per the project's release notes.
- Pros: commands are easier to remember, safer defaults for history editing, strong extension system.
- Cons: far fewer hosts and much less community material than Git; only 1.13% of survey respondents used it.
Fossil: version control, wiki and tickets in one file
Fossil was written by D. Richard Hipp (its first check-in is dated July 21, 2007 in the Fossil timeline) and its design reflects how the SQLite project works, according to Fossil's own comparison page. A whole repository is a single SQLite database file, and a single executable gives you version control plus an integrated wiki, bug tracker, forum, chat and web UI. Fossil's own Fossil vs Git page calls it close to "GitHub-in-a-box".
- Pros: one binary, one file per repo, built-in web interface (
fossil ui), easy self-hosting. - Cons: small community, no mainstream hosting service, deliberately discourages rewriting history.
Jujutsu (jj): a modern front end that speaks Git
Jujutsu is a newer open source version control system (Apache 2.0, about 32,000 GitHub stars as of November 2026) that uses Git repositories as its storage layer. Its README lists the ideas that make it beginner-friendly:
- No staging area. Your working copy is a commit and updates automatically.
- Operation log and undo. Every operation is recorded, and
jj undoreverses the last one. - Automatic rebase. Edit an old commit and everything after it is rebased for you.
- Conflicts are stored, not blocking. You can commit a conflict and resolve it later.
Because it reads and writes ordinary Git repositories, you can use jj on a GitHub project while teammates keep using Git. It is still pre-1.0 (0.46.0 as of October 2026), so expect occasional command changes.
Pijul: patches instead of snapshots
Pijul (GPLv2 or later) is built on a mathematical theory of patches. Its homepage highlights that independent changes can be applied in any order with the same result, merges preserve the order of lines, and once a conflict is resolved it never comes back. It also supports partial clones. Pijul is still in 1.0 beta (1.0.0-beta.26, October 30, 2026), has its own hosting service called the Nest, and is best treated as an interesting tool to try rather than one to build a team around today.
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 the popular Windows client TortoiseSVN released its matching 1.15.0 the same day), and it stays in use at companies with long-lived repositories, in some game and hardware teams, and where admins need per-folder permissions. In the 2022 Stack Overflow survey 5.18% of developers still used it, ahead of Mercurial. But almost all new open source projects and most job listings use Git, and GitHub, GitLab and Bitbucket are all Git hosts. If you are looking for an SVN alternative, Git (with git svn for migration) is the usual answer.
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.
Install Git. Download it from git-scm.com/downloads. On macOS,
xcode-select --installorbrew install gitalso works. On Windows, the installer includes Git Bash, a terminal where every command below works as written. On Debian or Ubuntu,sudo apt install git. Check it:git --versionSet 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 mainThe last line matters: until Git 3.0, an unconfigured
git initstill names the first branchmaster. Git 2.52's release notes announced that Git 3.0 will switch the default tomain, which GitHub and GitLab already use. If you want your email private on GitHub, use thenoreplyaddress shown in your GitHub email settings instead.Create a repository in a project folder:
mkdir hello-git && cd hello-git git init echo "# Hello Git" > README.mdgit initcreates a hidden.gitfolder. That folder is the repository; delete it and the history is gone, but your files stay.Stage and commit.
git addchooses what goes into the next snapshot;git commitsaves it:git status git add README.md git commit -m "Add README" git log --onelinegit statusis the command you will run most. It tells you which files are changed, which are staged, and what Git suggests you do next. Read its output; it is usually right.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. To build a
.gitignorefor your language and editor in one go, use DevHunt's free .gitignore generator.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-greetinggit switch(available since Git 2.23) is the clearer modern replacement for usinggit checkoutto change branches.Push to a remote. Create an empty repository on GitHub (or GitLab, Codeberg, or your own Gitea or Forgejo server), then:
git remote add origin https://github.com/your-name/hello-git.git git push -u origin mainGitHub no longer accepts account passwords for Git over HTTPS; use a personal access token, SSH key or GitHub CLI instead.
Get other people's changes. When a teammate pushes, bring their work into your copy:
git pullgit pullisgit fetch(download new commits) plus a merge into your branch. If you and a teammate changed the same lines, Git stops with a merge conflict; see the next section.
Resolving your first merge conflict
A conflict looks scary but is just Git asking you to choose. The file will contain markers like this:
<<<<<<< HEAD
Hello, world
=======
Hello, everyone
>>>>>>> add-greeting
The part above ======= is your current branch; the part below is the incoming change. Edit the file to the text you want, delete the three marker lines, then:
git add hello.txt
git commit
If you panic halfway, git merge --abort puts everything back to how it was before the merge. VS Code and most IDEs show conflicts with "Accept current / Accept incoming / Accept both" buttons, which is easier the first few times.
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 the last commit but keep its changes (not yet pushed) | git reset --soft HEAD~1 |
| Undo a pushed commit without rewriting history | git revert <commit> |
| Put work aside to switch branches | git stash, later git stash pop |
| 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.
On Windows, most SVN users never touch the command line: TortoiseSVN adds Subversion commands to the right-click menu in File Explorer and is free to use, even commercially.
The same first steps in Mercurial, Fossil, Jujutsu and Pijul
Once you know the Git loop, the other tools are mostly new spellings of the same ideas. These are the minimal "create a repo and make one commit" sequences for each.
Mercurial
hg init hello-hg && cd hello-hg
echo "# Hello" > README.md
hg add README.md
hg commit -m "Add README"
hg log
Mercurial has no staging area: hg commit commits all tracked changes. Set your name in ~/.hgrc under [ui] with username = Ada Lovelace <ada@example.com>.
Fossil
fossil init hello.fossil
mkdir hello && cd hello
fossil open ../hello.fossil
echo "# Hello" > README.md
fossil add README.md
fossil commit -m "Add README"
fossil ui
fossil ui opens the built-in web interface with timeline, wiki and tickets in your browser.
Jujutsu
jj git clone https://github.com/your-name/hello-git.git
cd hello-git
echo "more" >> README.md
jj st # the change is already in the working-copy commit
jj describe -m "Update README"
jj new # start the next change
jj log
jj undo # reverses the last operation
Pijul
pijul init hello-pijul && cd hello-pijul
echo "# Hello" > README.md
pijul add README.md
pijul record -m "Add README"
pijul log
In Pijul a commit is a change and you record it rather than commit it.
Best version control clients (GUIs) for beginners
You don't have to live in the terminal: most source control tools have a graphical client. In the 2022 Stack Overflow survey, 83.57% of developers used the command line for version control, but 54.49% also used their code editor and about a quarter used a dedicated GUI app. Most people mix them.
Multiple answers allowed. Source: Stack Overflow Developer Survey 2022, 68,156 responses
| Client | Works with | Platforms | Price / license | Why beginners like it |
|---|---|---|---|---|
| Your editor (VS Code, JetBrains IDEs) | Git (and more via plugins) | All | Built in | Stage, commit, diff and resolve conflicts without leaving the code |
| GitHub Desktop | Git | macOS, Windows | Free, open source (MIT) | The simplest Git GUI; great with GitHub, works with any remote |
| Sourcetree | Git | macOS, Windows | Free (Atlassian, not open source) | Visual branch graph, good for learning what commands do |
| lazygit | Git | All (terminal UI) | Free, open source (MIT) | Keyboard-driven, shows staging and branches at a glance |
| TortoiseGit | Git | Windows | Free, open source (GPL) | Right-click menu in File Explorer, familiar to SVN users |
| TortoiseSVN | SVN | Windows | Free, open source | The standard way to use SVN on Windows |
JetBrains IDEs, VS Code and most other editors ship Git support built in. For picking an editor in the first place, see our IDE comparison.
Where to host your repositories: GitHub, GitLab, Codeberg, Forgejo, Gitea
Git itself has no website. Version control hosting services store a copy of your repository online and add pull requests (or merge requests), issues, CI and access control. In the 2022 survey, GitHub led for personal use by a wide margin.
Multiple answers allowed. For professional use the figures were GitHub 55.93%, GitLab 28.9%, Bitbucket 18.42%, Azure Repos 9.94%. Source: Stack Overflow Developer Survey 2022, 67,035 responses
Newer numbers point the same way: GitHub's Octoverse 2025 report counts more than 180 million developers, 630 million repositories and nearly 1 billion commits pushed in its September 2024 to August 2025 year.
| Option | What it is | Free tier (as of November 2026) | Paid from | Best for |
|---|---|---|---|---|
| GitHub | Hosted Git (Microsoft) | Unlimited public and private repos, unlimited collaborators, 2,000 Actions minutes/month, 500 MB Packages | Team $4/user/month | Most beginners, open source, portfolios |
| GitLab | Hosted or self-managed Git with built-in DevOps | 5 users per private top-level group, 400 compute minutes/month, 10 GiB per project | Premium $29/user/month (annual) | Teams that want CI/CD and planning in one place |
| Codeberg | Non-profit host run by Codeberg e.V. (Berlin), built on Forgejo | Free, for free and open source projects | Donations / membership | Open source projects that want a community-run, non-commercial host |
| Forgejo | Self-hosted Git forge (what Codeberg runs) | Free software; GPLv3+ since v9.0 (MIT before). Latest 17.0.1, October 26, 2026 | Your own server cost | Self-hosting with a community-governed project |
| Gitea | Self-hosted Git forge, Forgejo's upstream | Free, open source (MIT). Latest 28.3.0, November 1, 2026 | Your own server cost, optional commercial support | Lightweight self-hosting on a small VPS or a Raspberry Pi |
Codeberg's homepage showed 455,619 users and 757,285 projects when we checked in November 2026. Its terms limit it to free and open source work, so private company code belongs on GitHub, GitLab, or your own Forgejo or Gitea server. For CI, deployment and other tools that plug into these hosts, browse DevOps tools on DevHunt.
Version control for binary files, data and non-programmers
Git stores every version of every file in full history, so a 200 MB video committed ten times makes the repository huge for everyone who clones it. Options:
- Git LFS (Large File Storage, latest 3.8.1 as of October 2026) keeps big files on the server and puts small pointer files in Git. GitHub, GitLab and most forges support it. Run
git lfs install, thengit lfs track "*.psd"and commit the generated.gitattributes. - SVN or Perforce handle huge binaries and file locking natively, which is why game studios still use them.
- DVC (Data Version Control, Apache 2.0) versions datasets and machine learning models alongside a Git repo, storing the data itself in cloud or local storage.
Version control is not only for code. Writers, designers and researchers use Git for Markdown documents, configuration and anything else that is text. Version control for non programmers works the same way: if you are not a programmer, start with GitHub Desktop or your editor's Git panel and treat each commit as a labeled save point.
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. - Add a
.gitignoreon day one, before the firstgit add ., so build output and secrets never get tracked. - Never rewrite history others have pulled.
rebase,commit --amendandpush --forceare fine on your own unpushed work and painful on shared branches. If you must force-push your own branch, usegit push --force-with-lease, which refuses to overwrite commits you haven't seen. - Push often. A laptop is not a backup until the commits are on a remote.
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. A good way to practice the full branch, commit and pull request loop is to contribute to a real project; see our list of open source projects to contribute to, or browse open source tools on DevHunt.
Common beginner mistakes (and how to fix them)
| Mistake | What happens | Fix |
|---|---|---|
Committing secrets (.env, API keys) |
Anyone with repo access, or the whole internet if public, can read them, even after you delete the file | Rotate the key immediately. Add the file to .gitignore. Cleaning history needs a tool like git filter-repo, and you must still assume the key leaked |
Committing node_modules/, build output or huge files |
Slow clones, bloated repo, noisy diffs | git rm -r --cached node_modules, add it to .gitignore, commit |
git add . without checking |
Unrelated or temporary files sneak into commits | Run git status and git diff --staged before every commit |
Working directly on main |
Hard to review, hard to undo, conflicts with teammates | git switch -c my-change before starting work |
| One giant commit per day | History is useless for finding bugs or reverting | Commit each logical change separately |
| Messages like "fix" or "wip" | Nobody (including future you) knows what changed | Write a short imperative summary: "Add password reset email" |
| Force-pushing a shared branch | Teammates' commits disappear from the remote | Use git revert on shared branches; --force-with-lease only on your own |
| "Detached HEAD" panic | You checked out a commit, not a branch, and new commits seem to vanish | git switch -c rescue-branch keeps them; git switch main goes back |
| Typing a password for GitHub over HTTPS | Push fails with an authentication error | Use a personal access token, SSH key or gh auth login |
| Editing the same lines as a teammate for days | Big, painful merge conflicts | Pull often and merge small branches quickly |
Honest limitations
- Git's learning curve is real: staging, rebasing and detached HEAD confuse everyone at first. Learn
status,add,commit,switch,merge,pull,pushbefore 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.
- The Stack Overflow survey dropped its version control question after 2022, so the usage percentages here are the most recent survey figures available, not 2026 numbers. GitHub's 2025 Octoverse figures are newer but only describe GitHub.
FAQ
What is an example of a version control system?
Git is the most common example. Others are Apache Subversion (SVN), Mercurial, Fossil, Jujutsu and Pijul (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, Codeberg, 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.
Source control vs version control: what is the difference?
There is none in practice. "Source control", "version control", "revision control" and "source code management (SCM)" are used interchangeably for tools like Git and SVN. Some people use "version control" more broadly for any file (documents, designs) and "source control" specifically for code, but the software is the same.
What is a local version control system?
Local version control tracks file history on one computer with no server, like the old RCS tool. Today, running git init and committing without ever adding a remote gives you the same thing with a much better tool, and you can push to GitHub or another host later.
Is Git free and open source?
Yes. Git is free and open source under the GNU GPL version 2. It costs nothing to install or use, commercially or personally. Paid plans exist only for hosting services like GitHub and GitLab, and their free tiers cover most individuals.
What are the best version control clients for beginners?
Start with the Git panel in your code editor (VS Code, JetBrains IDEs) or GitHub Desktop, which is free and open source. Sourcetree adds a visual branch graph, lazygit is a fast terminal UI, and TortoiseSVN is the standard SVN client on Windows.
Is there free version control software other than Git?
Yes. Apache Subversion, Mercurial, Fossil, Jujutsu, Pijul and Breezy are all free and open source. Jujutsu is the easiest to try alongside Git because it uses Git repositories directly.
Which version control system for binary files should I use?
For a few large files in a Git project, use Git LFS. For very large binary assets with file locking (games, hardware, video), centralized systems like SVN or commercial Perforce P4 are common. For datasets and machine learning models, DVC works alongside Git.
What is the best version control for single developer projects?
Git, even when you work alone: it gives you history, undo and branches, and a free private repository on GitHub or GitLab doubles as an off-site backup. If you want code, wiki and issue tracking in one self-contained file without any hosting service, Fossil is a good alternative.
