Git Graph for GitHub

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 remote code, and no content scripts injected into the pages you visit • No personal data, repository names, commit SHAs, URLs, or page content is ever collected or transmitted • GitHub requests go directly from your browser to github.com and api.github.com • Anonymous usage and error stats are sent via Aptabase, a privacy-first analytics service, to help improve the extension — on by default, and you can turn it off anytime from the options page. No cookies, no persistent identifiers, so events can't be tied to you or correlated across sessions. Builds without an Aptabase key send nothing • The only data stored locally is your preferences (theme, default graph mode) and the list of recently opened repositories 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.
