GitHub Search is a free Chrome add-on developed by ushi. It falls under the category of Browsers and specifically the subcategory of Add-ons & Tools. This program allows users to search GitHub repositories directly from their Omnibar.

With GitHub Search, users can simply type 'gh' followed by a space or tab in the Omnibar, and then enter their desired search term. The add-on supports various types of queries, including searching for GitHub repositories based on a specific search term, searching for repositories of a particular user, searching for GitHub users, and even searching the extension's history.

This convenient add-on eliminates the need to navigate to the GitHub website separately for searching repositories or users. GitHub Search provides a quick and efficient way to access GitHub's vast collection of code repositories, making it a valuable tool for developers and GitHub users.
