git-fame calculates contributor statistics from the history of a Git repository. Rather than relying solely on the number of commits, it can examine surviving lines of code and group the results by the people credited with those changes.
This type of report helps teams understand how ownership is distributed, which contributors have shaped particular parts of a codebase and how different subsets of the repository compare. The tool also provides controls for adjusting which paths and changes enter the calculation.
A commit count by itself can be misleading because one commit may touch a single line while another changes thousands. A line-oriented attribution report provides another perspective, especially when combined with path selection and whitespace handling. Results should still be interpreted as historical statistics, not a formal measure of contribution quality.
This is free and open source software.
Key Features
- Ranks contributors by lines, commits and other measures derived from Git history.
- Produces tabular output suitable for quick inspection of repository contributors.
- Can analyse selected subdirectories and file extensions rather than the entire project.
- Allows files and paths to be explicitly included or excluded from the calculation.
- Can ignore whitespace-only edits when attributing surviving lines.
- Supports date-based filtering of historical contributions.
- Can recursively discover repositories and submodules for broader analysis.
- Provides optional time-cost estimates in person-hours or person-months.
- Cross-platform support – runs on Linux, macOS, and Windows.
