GitHub Tools Switcher Chrome Extension

This Chrome extension allows you to quickly switch any GitHub repository URL to a variety of developer-focused tools (such as DeepWiki, GitHub.dev, etc.) while preserving the original path and query parameters.

Features

• Popup Menu – Click the extension icon to open a list of tools. Selecting one instantly navigates the current GitHub tab to the chosen service.
• Inline Toolbar – When browsing a GitHub repository page, a small toolbar (🛠️) is injected into the repository header for one-click access to all supported tools in a new tab.
• Non-destructive URL Transformation – The repository path and query string are kept intact; only the domain is swapped (e.g. github.com → deepwiki.com).

Supported Tools

Tool	Domain	Purpose
DeepWiki	deepwiki.com	Wiki generation by Devin
GitHub Dev	github.dev	Web-based VS Code editor
Code Wiki	codewiki.google	Code documentation by Google
