GitHub Repository Size от Pranav Mangal

A simple browser extension that displays the size of a GitHub repository on its homepage.

It is designed to integrate well with GitHub's responsive interface and also with the Refined GitHub browser extension.

It also supports displaying the sizes for non-public repositories by allowing you to submit a GitHub personal access token with the necessary permissions. Click on the extension icon to set this.
