netto

Find out how much of your codebase you actually wrote.

netto is a fast Rust CLI that counts your lines of code — and separates what you built from what your framework scaffolded for you. It reads your git history, detects your stack, skips generated files, and gives you an honest score.

Usage

# Scan the current directory
netto

# Scan a specific project
netto ~/projects/myapp

# Subtract a framework baseline (only count what you added)
netto --baseline ~/fresh-react-app

# Filter git stats to a specific author
netto --author "Your Name"

# Skip git analysis
netto --no-git

# Output as JSON
netto --json

How it works

Line counting — netto reads every file in your project, skips blank lines and comments, and separates code from config and markup. Auto-generated files (detected by header comments like // auto-generated) are excluded entirely.

Framework baseline — point --baseline at a fresh scaffold of your framework and netto subtracts those lines from your count. What's left is the code you actually wrote.

"I wrote this" score — your git-attributed additions divided by total source lines. A humble number is normal. Most projects are 20–40% original.

Commit streak — consecutive days you've made at least one commit. Counts backward from today.

Problem children — files changed most frequently in git history. Usually where the complexity lives.
