When starting to work on a project, it's common to wonder whether to fork an existing repository or create a new branch for it. Before making this decision, it's important to consider the key differences between the two options.
Generally, branching is a default option if you're working on a team developing a product. However, if you run into someone else's product and have new ideas you want to try, then forking is a good option because you can work on your ideas in isolation.
Tip: If unsure ask yourself 3 questions... If your answer is 'no' to any of the following questions, then you should go for a fork:
| Fork | Branch | |
| Purpose | Create a separate copy of a repository for significant changes or different directions | Develop new features or fix bugs without disrupting the main codebase |
| Relationship to the original codebase | Completely independent repository | Linked to the original repository |
| Ownership | Owned by the user who created them | Owned by the repository owner |
| Scope of changes | Typically involve significant changes | Typically involve smaller changes |
| Collaboration | Used to develop ideas in isolation from the main team | Used to develop ideas that the main team is working on |
