Github File Tree (Octofree) by Andrii Trybynenko

Octofree adds a collapsible file tree sidebar to any GitHub repository page, so you can navigate large codebases without ever leaving the page.

Features

• 🌲 File tree sidebar — browse a repository's full structure at a glance
• 🔀 Branch switching — jump between branches without reloading
• 🔍 File search — find any file instantly with autocomplete (press / to focus)
• ⬇ Direct downloads — grab a single file with one click
• 🔒 Private repo support — optionally add a GitHub Personal Access Token
• 🌙 Dark theme — a distinctive, eye-friendly UI

Pull request mode

• 🔁 Toggle the sidebar between Branches and Pull Requests and browse any open PR's file tree
• 📊 Inline diff stats — +added / −removed line counts next to each changed file
• 🔗 One-click diff view — jump straight to a file's diff in the "Files changed" tab
• 👁 Docs & agent-config filter — narrow the tree to markdown docs and AI agent folders (.claude, .github, .cursor and more)
• 📌 Persistent sidebar — remembers whether it is open and which view you used last

Privacy

Everything runs locally in your browser. No analytics, no tracking, and nothing is sent to the developer. If you add a GitHub Personal Access Token it is stored only in browser storage and used solely for direct requests to api.github.com.
