Download of GitGrass 2.4 for Mac was available from the developer's website when we last checked. We cannot confirm if there is a free download of this app available. The application lies within Developer Tools, more precisely Webmaster Tools. This free software for Mac OS X is a product of Takuto Nakamura. According to the results of the Google Safe Browsing check, the developer's site is safe. Despite this, we recommend checking the downloaded files with any free antivirus software.
From the developer:
GitGrass is a utility tool designed to help you check the contributions of GitHub. The application installs in the menu bar of your Mac so you can access it with ease any time you want. The tool updates data from Github periodically, at a time interval you select from the update cycle profiles.
