About GitHub Jupyter Notebook Diff Viewer
# github_ipynb
A Chrome extension that makes GitHub .ipynb diffs suck less.
When viewing Jupyter Notebook changes in GitHub pull requests, GitHub normally shows massive raw JSON diffs that are painful to review. github_ipynb injects a notebook-aware diff viewer directly into GitHub so you can actually understand what changed.
## What it does
- Detects .ipynb notebook diffs on GitHub PR pages
- Adds a “View Notebook Diff” button to notebook files
- Renders markdown cells as formatted markdown
- Syntax highlights code cells
- Shows added, removed, and modified cells clearly
- Collapses notebook outputs by default to reduce noise
- Runs entirely in the browser with no backend
## Why?
Jupyter notebooks are great for experimentation and terrible for traditional git diffs.
Even tiny notebook changes can generate unreadable JSON changesets full of metadata and output noise. This extension provides a cleaner review workflow directly inside GitHub.
## Current Limitations
This is currently an MVP and focuses on:
- Public GitHub repositories
- Pull request notebook diffs
- Browser-only rendering
Cell matching is currently heuristic-based and may not perfectly detect moved cells or heavily reorganized notebooks.
## Open Source
Source code:

## Privacy
This extension does not collect analytics, tracking data, or personal information.
All notebook parsing and rendering happens locally in your browser.
