Git is overwhelmingly more popular than SVN (Subversion) in the current landscape of version control systems.
Here's a summary of the popularity comparison:
- Dominant Leader: Git has been the undisputed leader for over a decade.
Recent surveys, like the Stack Overflow Developer Survey, consistently show Git adoption rates well over 90%. For example, in 2025, Git's usage is estimated to be around 93.87%. - SVN's Decline: SVN, while once widely used (it was the dominant system before Git), has seen a significant decline in popularity.
Its usage is now typically in the low single digits, around 5% according to recent data. - Reasons for Git's Popularity:
- Distributed Nature: Git is a Distributed Version Control System (DVCS), meaning every developer has a full copy of the repository.
This allows for offline work, faster commits, and a more robust system with no single point of failure. - Branching and Merging: Git's branching and merging capabilities are highly efficient and flexible, making it ideal for collaborative development, especially in open-source projects and agile environments.
- Ecosystem: Git has a massive ecosystem of tools, hosting services (GitHub, GitLab, Bitbucket), and a vibrant community.
- DevOps and Agile: Git's features align well with modern development practices like DevOps and agile methodologies.
- Distributed Nature: Git is a Distributed Version Control System (DVCS), meaning every developer has a full copy of the repository.
- Where SVN Still Sees Use:
- Legacy Projects: Many older enterprise projects that built their infrastructure around SVN continue to use it.
- Specific Use Cases: SVN can sometimes be preferred for projects that require fine-grained access control down to the file or directory level, or in situations where handling large binary files with strict file locking is a priority (though Git LFS helps address this in Git).
- Simplicity for Beginners: Some argue that SVN has a simpler learning curve for absolute beginners due to its centralized and more straightforward approach.
- Legacy Projects: Many older enterprise projects that built their infrastructure around SVN continue to use it.
In essence, while SVN still exists and is used in some niche or legacy contexts, Git has become the de facto standard for new software development projects globally.
