A privacy-focused CLI tool that analyzes local Git repositories to visualize commit patterns, code churn, and developer productivity metrics using beautiful terminal visualizations with Rich. Runs entirely offline with no external data transmission.
## Features
- **Local Repository Analysis** - Analyze any local git repository without data transmission
- **Commit Activity Heatmap** - Display daily/weekly commit patterns as a GitHub-style heatmap
- **Code Churn Tracking** - Track lines added/deleted over time with trend visualization
- **Author Contribution Breakdown** - Show commit count, code changes, and contributions per author
- **Productivity Scorecard** - Calculate productivity scores based on commits, changes, and patterns
- **File Change Frequency** - Show most frequently changed files in the repository
- **Export Reports** - Export analysis results to Markdown and JSON formats
- **Time Range Filtering** - Filter analysis by custom time ranges (last week, month, custom dates)
## Why GitPulse?
In an era of increasing data privacy concerns, GitPulse stands out by:
- **100% Offline** - All data is processed locally and never transmitted
- **No External Dependencies** - No API calls, no cloud services, no tracking
- **Privacy First** - Your repository data stays on your machine
- **Beautiful Terminal UI** - Built with Rich for stunning visualizations
