Git Without a Server: Using Your Local Filesystem as a Remote

By Mike Levin

Introductory Context

This text delves into a specific technique for using Git, a widely adopted system for tracking changes in computer files, most commonly source code. While many developers use Git by connecting to online hosting services like GitHub or GitLab (often called “remote servers”), this article explores how to leverage Git’s powerful features—like tracking history and managing different versions (branching)—entirely on your own local computer without needing any external server or even an internet connection.

The core idea presented is setting up a special type of Git repository, known as a “bare” repository, in one directory on your computer. This bare repository acts as a central hub containing only the project’s history. You can then create working copies of your project in other directories and synchronize changes with this central bare repository using standard Git commands, all happening directly on your local filesystem. This approach is useful for personal projects, learning Git concepts in isolation, or ensuring complete privacy.

You don’t need GitHub For Everything

You can do a lot of what GitHub has to offer directly on your own machine. You don’t even need a git server. If you’re just using git for its unlimited undo and branching ability, you can use git against your native filesystem paths. This technique gets your code into at least 2 places on your system.

Question: I’m running a git repo locally off of the filesystem with no server. The path is /home/username/git-repos. How do I make a repo and commit and push to it from elsewhere.

Answer: Okay, you can definitely use a directory on your local filesystem as a central Git “remote” repository. The key is to create a bare repository in your central location (/home/username/git-repos). A bare repository doesn’t have a working directory (the files you edit); it only contains the Git version history data (usually stored in the .git folder).

Here’s how you can set it up and use it:

1. Create the Central Bare Repository

First, you need to create the repository in your central location. Let’s call your project my-project.

# Navigate to your central repository storage directory
cd /home/username/git-repos

# Create a new BARE repository for your project
# The .git suffix is a common convention for bare repositories
git init --bare my-project.git

This command creates a directory named my-project.git inside /home/username/git-repos. This directory contains the Git database but no checkout of the files themselves. This is what you want for a central repository that you push to and pull from.

2. Clone the Repository to Your Working Location

Now, go to the location where you actually want to work on the project files (your “working copy”). Clone the bare repository using its filesystem path.

# Navigate to where you want your working copy
# For example, let's put it in a 'projects' directory
cd /home/username/projects  # Or any other location

# Clone the bare repository using its path
# Git will create a directory named 'my-project' here
git clone /home/username/git-repos/my-project.git

This command does a few things:

• Creates a new directory named my-project (or whatever you named the source repo without the .git).
• Copies the Git history from the bare repository.
• Checks out the latest version (though initially, it’s empty).
• Sets up a “remote” named origin automatically, pointing back to /home/username/git-repos/my-project.git. You can verify this:

    cd my-project
    git remote -v
    # Output will show origin pointing to /home/username/git-repos/my-project.git
  

3. Work, Commit, and Push

Now you can work in your /home/username/projects/my-project directory just like any other Git repository:

# Navigate into your working copy directory
cd /home/username/projects/my-project

# Create some files
echo "# My Project" > README.md
echo "Initial content." > file1.txt

# Stage the new files
git add README.md file1.txt
# or git add .

# Commit the changes
git commit -m "Initial commit with README and file1"

# Push the changes to your central bare repository
# 'origin' is the default name for the remote pointing to your bare repo
# 'main' is the default branch name in newer Git versions (it might be 'master' in older versions)
git push origin main

Now, your changes are safely stored in the central bare repository located at /home/username/git-repos/my-project.git.

Summary:

1. Central Repo Creation: Use git init --bare /path/to/central/repo.git
2. Working Copy Creation: Use git clone /path/to/central/repo.git /path/to/working/copy
3. Workflow: Work in the /path/to/working/copy, use git add, git commit, and git push origin <branch-name> to send changes back to the central repository.

You can clone this same central repository (/home/username/git-repos/my-project.git) to other locations on your filesystem if needed, and use git pull origin <branch-name> in those other locations to get the latest changes.

Question: Does git have its own built in git server? And is that necessary here?

Answer:

1. Does Git have its own built-in Git server?

   Yes and no. Git itself is primarily a distributed version control system, meaning it doesn’t require a central server to function. However, Git does come with a command called git daemon.

   • git daemon: This is a very basic server included with Git distributions. It allows serving Git repositories over the network using the git:// protocol. It’s generally used for providing unauthenticated (or simple path-based authenticated) read access to public repositories. It’s less common for private development work compared to SSH or HTTPS.

   • Common Alternatives (Not Built-in to Git Core): Most remote Git hosting (like GitHub, GitLab, Bitbucket, or self-hosted solutions) uses standard protocols like:

     • SSH (ssh://): Requires an SSH server (like OpenSSH sshd) running on the machine hosting the repository. This is very common and secure.
     • HTTPS (https://): Requires a web server (like Apache or Nginx) configured with specific Git helper programs (git-http-backend). This is also very common and secure.

   So, while Git provides git daemon, it doesn’t include the more commonly used SSH or full-featured HTTPS servers directly within its own core package.

2. Is that necessary here?

   No, a Git server process (like git daemon, sshd, or a web server) is absolutely not necessary for your specific setup.

   You are accessing the bare repository (/home/username/git-repos/my-project.git) directly via its filesystem path. Git is perfectly capable of treating a local directory path as a “remote”. When you run commands like:

   git clone /home/username/git-repos/my-project.git
   git push origin main
   git pull origin main
   

   Git recognizes that /home/username/git-repos/my-project.git is a local path. It uses the local file protocol to read from and write to the repository files directly. No network communication or separate server process is involved.

   Using a bare repository on the local filesystem, as you described, is a simple and effective way to have a central point for your repositories on a single machine without needing any network configuration or server daemons. Let’s break down those questions:

3. Does Git have its own built-in Git server?

   • Yes, sort of. Git comes bundled with a command called git daemon. This is a very basic server that serves repositories over the git:// protocol.
   • Limitations: git daemon is generally unauthenticated (though some basic controls exist). This means anyone who can reach the server over the network can typically clone (read from) the repositories it serves. Enabling push (write) access without authentication is highly discouraged due to security risks. It’s also less common than using SSH or HTTPS.
   • Common Alternatives: More commonly, Git repositories are served over networks using:
     • SSH: Leverages the existing Secure Shell daemon (sshd) found on most Linux/macOS systems. Authentication is handled via SSH keys or passwords. This is very common for private repositories.
     • HTTPS: Uses a standard web server (like Apache or Nginx) configured to understand Git requests. Authentication often uses username/password or tokens. This is how services like GitHub, GitLab, etc., primarily operate.
   • Conclusion: While git daemon exists and is built-in, it’s quite basic. Most network access relies on integrating Git with standard SSH or web server software, which are not part of Git itself.

4. Is that necessary here?

   • No, absolutely not necessary for the scenario you described (accessing a bare repository on the same local filesystem).
   • Why? When you use a filesystem path like /home/username/git-repos/my-project.git as the URL for cloning or as a remote, Git uses the local protocol. It simply reads and writes directly to the files in that directory using standard filesystem permissions.
   • No Network, No Server Process: There’s no network communication involved, so there’s no need for git daemon, sshd, or a web server to be running to handle Git requests. Git interacts with the bare repository directory just like it interacts with the .git directory inside your working copy – through direct file access.

In summary: Git has a basic built-in daemon, but you don’t need any server process (neither git daemon nor SSH/HTTP servers) when your “remote” repository is just another directory on your local machine.

Question: What is the utility of working this way?

Answer: Working this way – essentially Git talking to itself on your own filesystem – might seem a bit insular at first glance, especially in our hyper-connected world where collaboration often defaults to cloud platforms like GitHub or GitLab. But it taps into some core strengths of Git and serves several useful purposes:

1. The Ultimate Sandbox & Learning Environment: It’s perhaps the purest way to learn and experiment with Git’s remote concepts (pushing, pulling, cloning, bare vs. non-bare repos) without any external dependencies. No need for accounts, SSH keys, network configurations, or even an internet connection. You can simulate a client-server workflow entirely locally, making mistakes consequence-free (beyond your own filesystem). It’s a safe, private digital sandbox.

2. Speed Demon: Operations are lightning fast. Cloning, fetching, and pushing to a local filesystem path involves direct file copying and hardlinking (where possible). There’s no network latency, no authentication overhead, no server processing time. For large repositories or frequent operations on a single machine, this speed difference can be noticeable compared to even a fast local network connection, let alone the public internet.

3. Strict Project Separation & Organization: It provides a clean architectural separation, even on a single machine. The bare repository (/home/username/git-repos/my-project.git) becomes the definitive, pristine history – the “source of truth.” Your working directory (/home/username/projects/my-project) is where the messy work happens. This can be useful for:
   • Maintaining a “clean” version separate from development experiments.
   • Having multiple working directories clone from the same local bare repo for different tasks (e.g., one for feature dev, one for documentation, one for release testing) but synchronizing through a central local hub.
   • Scripting workflows where you want to interact with the canonical history without needing a full working copy checked out.

4. Enhanced Local Backup Strategy Component: While not a replacement for off-site backups, the bare repository is a complete, independent copy of your project’s history. If your working directory somehow gets irrevocably messed up (e.g., accidental rm -rf .git, catastrophic failed merge you can’t undo), you can simply delete it and re-clone from the local bare repo. The bare repo itself is simpler and less likely to be corrupted by interactive commands. Of course, you still need to back up the bare repository directory itself, preferably off-machine!

5. Total Privacy & Offline Capability: Your entire Git workflow stays on your machine. The history, the commits, everything. There’s no third-party service involved, no data transmitted over any network (unless the filesystem itself is network-mounted, which is a different scenario). This is ideal for sensitive projects, initial brainstorming, or simply working entirely offline for extended periods.

6. Foundation for Simple Sharing (with caveats): If /home/username/git-repos were on a shared network drive (like NFS or Samba) accessible by a small, trusted team, this setup could function as a rudimentary shared server without needing dedicated Git server software or SSH access management on a separate machine. Performance might vary, and filesystem locking could potentially become an issue with simultaneous writes, but for simple cases, it can work.

The Flip Side (Limitations):

Its main limitation is obvious: collaboration beyond a shared filesystem is impossible. This method doesn’t scale to distributed teams. It also lacks the ecosystem benefits of platforms like GitHub/GitLab (issue tracking, pull requests, CI/CD, web UI, discovery). And, as mentioned, it doesn’t automatically solve off-site disaster recovery.

In Essence:

Working this way is like having a private conversation with yourself using the robust language of Git. It emphasizes Git’s distributed nature (even if the “distribution” is just between two directories on one disk), leverages its versioning power for personal organization and safety, and provides a friction-free environment for learning and experimentation. It’s a simple, powerful technique for specific local use cases, even in 2025.
