git-fame is a third-party Git tool that provides a repository-wide overview of code authorship by aggregating data from git blame across all files or specified paths.

Instead of per-file line-by-line details, it ranks the top contributors (authors or files) by lines of code authored or commits touched. This helps visualize who owns the most code, spot hotspots, or generate fun leaderboards for teams.

By default, it displays the top 15 authors sorted by line count in a formatted table, including percentages and totals. Options allow customization like commit-based stats, file views, ignoring merges, or relative blaming.

Ideal for code audits, onboarding docs, or contribution analysis in open-source projects. Written in Rust for speed, but may take time on massive repos due to full blame traversal.

Not a core Git command; install separately. Slow on large repos due to full git blame runs. Requires Git repository context.

Linux: cargo install git-fame
Or via package managers like Homebrew/apt if available.

git fame --top 5 --authors
Shows top 5 authors by lines: table with name, lines, %.
git fame --commits src/
Limits to src/ dir, commit counts.

Developed by Chris Emerson in Rust, first released in 2018. Popular on GitHub (cgarnier/git-fame fork active), used for quick repo blame summaries in dev teams.
