As a developer, you’ve probably encountered the dilemma of converting a GitHub fork to a standalone repository. Maybe you’ve spent weeks, or even months, building upon someone else’s code, and now it’s time to set your project free. But, when you’re faced with the option to “Detach” or “Extract” your fork, you’re left wondering: what’s the difference?
The Million-Dollar Question: Detach or Extract?
Before we dive into the nitty-gritty, let’s clarify the objective: you want to transform your fork into a separate, independent repository that’s no longer tied to the original project. This process is called “converting” or “breaking away” from the parent repo.
The GitHub interface presents you with two options: “Detach” and “Extract.” While they might seem similar, each path has distinct consequences for your repository’s history, structure, and future development.
The “Detach” Option: A Clean Break
- No commit history ties to the original repo: Your new repository begins with a clean slate, free from the baggage of inherited commits.
- No future updates from the parent repo: You won’t receive automatic updates from the original project, ensuring your codebase remains untouched.
- Full control over your repository’s structure: You can reorganize your project’s directories, files, and branches without worrying about conflicting with the parent repo.
However, “Detach” also means you’ll lose the commit history and any linked issues or pull requests from the original repository. This might not be ideal if you want to maintain a clear record of your project’s evolution or need to reference past bug fixes.
The “Extract” Option: Preserving History and Links
By selecting “Extract,” you’ll create a new repository that retains the commit history and links to the original project. This approach is suitable when:
- You want to preserve the commit history: Your new repository will contain all the commits from the original project, allowing you to track changes and collaborate with others.
- You need to maintain links to issues and pull requests: Any open or closed issues, pull requests, or comments will be transferred to your new repository, ensuring continuity.
- You want to allow future updates from the parent repo (optional): You can choose to allow the new repository to receive automatic updates from the original project, ensuring you stay in sync.
However, “Extract” also means your new repository will inherit the original project’s structure, which might not align with your vision. You’ll need to be mindful of potential conflicts and take steps to refactor your codebase as needed.
A Step-by-Step Guide to Converting Your Fork
Now that you understand the differences between “Detach” and “Extract,” let’s walk through the conversion process:
Step 1: Access Your Forked Repository
Navigate to your forked repository on GitHub and click on the “Code” button. Then, select “Convert to standalone repository” from the dropdown menu.
https://github.com/your-username/your-forked-repo
Step 2: Choose Your Conversion Method
GitHub will present you with the “Detach” and “Extract” options. Select the one that best suits your needs, considering the trade-offs discussed earlier.
Step 3: Configure Your New Repository (Optional)
If you chose “Extract,” you’ll have the opportunity to:
- Choose whether to allow future updates from the parent repo
- Select the branches you want to transfer (e.g., main, dev, or custom branches)
- Decide which commit history to preserve (e.g., all commits or a specific range)
Step 4: Review and Confirm
Carefully review the conversion summary, ensuring you understand the implications of your chosen method. If everything looks correct, click “Convert repository” to complete the process.
Troubleshooting and Post-Conversion Tips
After converting your fork, you might encounter some issues or need guidance on how to proceed:
Handling Commit History Conflicts
If you chose “Extract” and encounter commit history conflicts, you can use Git commands to resolve them:
git pull --rebase origin
git push --force origin main
Maintaining Links to Issues and Pull Requests
To ensure linked issues and pull requests remain connected, update the URL in your new repository’s settings:
https://github.com/your-username/your-standalone-repo/issues
Updating Your Repository’s Structure
Take this opportunity to refactor your codebase, reorganize directories, and adjust branching strategies as needed.
| Task | Git Command |
|---|---|
| Rename a directory | git mv old-name new-name |
| Delete a branch | git branch -d branch-name |
| Create a new branch | git branch new-branch |
Conclusion
Converting a GitHub fork to a standalone repository is a significant milestone in your project’s life cycle. By understanding the differences between “Detach” and “Extract,” you can make informed decisions about your repository’s structure, commit history, and future development.
Remember to carefully consider your options, configure your new repository accordingly, and troubleshoot any post-conversion issues. With this guide, you’ll be well on your way to unleashing your standalone repository into the world.

Frequently Asked Question
Still confused about the difference between “Detach” and “Extract” when converting a GitHub fork to a standalone repo? We’ve got you covered!
What is the main difference between “Detach” and “Extract”?
The main difference lies in how they handle the fork’s history. “Detach” breaks the connection with the original repository, but keeps the entire fork history, including commits and pull requests. On the other hand, “Extract” creates a new repository with a rewritten history, removing any unnecessary commits and pull requests.
When should I use “Detach” instead of “Extract”?
Use “Detach” when you want to preserve the entire history of the fork, including all commits and pull requests. This is useful when you need to maintain a record of changes or collaborate with others who rely on the existing history.
What are the advantages of using “Extract” over “Detach”?
“Extract” provides a cleaner and more streamlined repository history, which can make it easier to manage and maintain. It also reduces clutter and removes unnecessary commits, making it ideal for repositories with a complex history.
Can I use both “Detach” and “Extract” together?
While it’s technically possible, it’s not recommended to use both “Detach” and “Extract” together. “Detach” preserves the entire history, whereas “Extract” rewrites it. Using both would result in a redundant and potentially confusing repository history.
How do I decide which option to choose for my GitHub fork?
Consider the purpose of your repository and the needs of your team. If you need to maintain a record of changes or collaborate with others who rely on the existing history, use “Detach”. If you want a cleaner and more streamlined repository history, use “Extract”.
