Repolyze

repolyze is a Rust-based repository analysis tool for one or more already-cloned local Git repositories. It is designed as a TUI-first application with optional CLI commands for users who want scriptable analysis without the interactive interface.

The initial product scope focuses on:

• user contribution statistics from Git history
• most active hours and days based on commit activity
• GitHub-style activity heatmap showing daily commits over the past year
• multi-repository comparison with per-repo and per-weekday rankings
• language-agnostic repository size comparison
• scrollable full-screen TUI with background analysis and animated spinner
• JSON and Markdown report output

Who is Repolyze for?

• Team Leads — Track team member contributions and effort across repositories. See who's active, how workload is distributed, and where the team's energy goes.
• Tech Leads — Get actionable insights across company repositories. Compare codebases side by side, spot activity trends, and make data-driven decisions about your engineering portfolio.
• Individual Contributors — Understand your own contribution patterns. Track your output over time, see where your effort goes, and benchmark your activity across projects.
