Git Graph for GitHub

About

Visualize the full GitHub commit network — including forks — in a clean,
VSCode-Git-Graph-style viewer that opens in its own browser tab.

GitHub's built-in network graph is great for a quick glance, but the moment
you actually want to read a commit message or see which fork diverged where,
you end up clicking through five separate pages. Git Graph for GitHub puts
the graph and a full commit detail panel side by side, so you can explore a
repository's history (and its entire fork family) without leaving the tab.

KEY FEATURES

• Commit graph for any public GitHub repository, rendered in a dedicated tab
• Virtualized rendering — large histories stay smooth and responsive
• Fork-aware: switch between "Main only" (the focus repo's branches) and
  "Include forks" (the full network)
• Commit detail panel with parent / child navigation and a per-file diff
  summary (additions, deletions, status)
• Right-click a commit to copy its SHA or subject, or jump to a parent
• Recent repositories list in the toolbar popup
• Dark and light themes
• English and Japanese UI (automatic, based on Chrome's language setting)

WHY YOU MIGHT WANT IT

• You contribute to or maintain open-source projects with many forks and
  want a faster way to see who diverged, when, and why
• You like VSCode's Git Graph extension and want a similar experience in
  the browser, without cloning the repo locally
• You're researching a project before contributing and want to understand
  its structure at a glance

PRIVACY

• No analytics, no tracking, no remote code
• All requests go directly from your browser to github.com and
  api.github.com — nothing is routed through any third-party server
• The only data stored locally is your preferences (theme, default graph
  mode) and the list of recently opened repositories
• No content scripts are injected into pages you visit

PERMISSIONS

• storage — save your preferences and recent repositories locally
• activeTab — read the URL of the current tab when you open the popup, so
  it can offer to graph the repo you're looking at
• Access to github.com and api.github.com — to fetch the commit network
  and per-commit details on demand (unauthenticated, subject to GitHub's
  60 requests/hour rate limit)
