GitHub Tree Navigator

About

GitHub Tree Navigator adds a fast, collapsible file-tree sidebar to GitHub so you can explore repositories and pull requests without losing context.

Browse files instantly, search large repositories in real time, and move through GitHub with far fewer clicks. The sidebar is built directly into github.com pages, matches GitHub’s light and dark themes automatically, and works without any backend or external service.

Key features

- Instant file tree for GitHub repositories
- Live search and filtering for files and folders
- Pull request changed-files mode for faster review navigation
- Active-file highlighting while browsing source files
- Quick file actions: copy path, copy permalink, open raw, open blame, and open history
- Resizable sidebar with saved width
- Pin mode to keep the sidebar visible while navigating
- Expand all / collapse all controls with safeguards for very large repositories
- Keyboard navigation for faster workflows
- Automatic large-repository fallback when GitHub truncates the recursive tree
- Private repository support with a GitHub Personal Access Token
- Session cache to reduce unnecessary refetching while revisiting the same repo, branch, or pull request
- Built for developers

GitHub Tree Navigator is designed for people who spend time reading code, reviewing pull requests, and navigating large repositories. It focuses on speed, low friction, and privacy.

- No backend
- No tracking
- No analytics
- No popup
- No service worker
- Minimal permissions only
- Privacy and permissions

This extension only requests the permissions needed for its core functionality. If you add a GitHub Personal Access Token for private repositories or higher API limits, it is stored locally in your browser and only used to call the GitHub API. Your data is not sold, shared, or sent to any external service.

Why use it

GitHub’s default interface is powerful, but navigating large projects or pull requests can still be slow and repetitive. GitHub Tree Navigator gives you a persistent, searchable file tree exactly where you need it, so you can move through code faster and stay oriented.

Install GitHub Tree Navigator and make repository browsing on GitHub faster, cleaner, and more efficient.
