In plain English

Octotree is a browser extension that makes browsing code on GitHub much easier. Instead of clicking through folders one at a time to find a file, Octotree adds a sidebar panel to GitHub that shows the entire repository as a tree of folders and files, similar to how a code editor like VS Code displays your project on the left side. You can navigate directly to any file with a single click. It works on Chrome, Firefox, Edge, Safari, Opera, and Brave. Once installed, it activates automatically when you visit GitHub, giving you a clearer view of large or unfamiliar repositories without having to keep navigating back and forth. This is useful whenever you are exploring a new open-source project and want to understand its structure quickly, or when reviewing someone else's code and need to jump between files efficiently. It is also helpful for code review, where you need context from multiple files at once. The extension is built in JavaScript. Note that while an older limited version of the source code is publicly available in this repository, Octotree is proprietary software, the full product is distributed through browser extension stores and managed by the Octotree team.
