## Description

A simple extension that adds a repository size breakdown to the GitHub sidebar, so you have a better idea of how much you're about to clone.
GRSize doesn't show ads and doesn't collect any user data. It is fully open-source <a href="https://prod.outgoing.prod.webservices.mozgcp.net/v1/8fcc832bdf5077b2fff671da058af3fd4177a8b413336c70bdc27b8c7ff9abd7/https%3A//github.com/pluvivanto/GRSize" rel="nofollow">https://github.com/pluvivanto/GRSize</a>

Note: The numbers come directly from GitHub's API. Expect 10-20% increase in actual disk usage due to filesystem block allocation and Git metadata.
