Git Graph for GitHub

Visualize the GitHub commit network (forks + main repo) in a dedicated tab. Manifest V3, no remote code, no telemetry.

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) Open-source under the MIT license.
