To view Official repository, Please visit home page of the project of interest, and click on "version control", or to use the "repository viewer" link on the project home page.
In Addition, some unofficial mirrors have been set up for users of version control systems other than GIT. While it is important to contribute your code back to Drupal's official repository, having a mirror available in your preferred version control system can be useful at times.

Acquia also maintains a Subversion repository for the Acquia Drupal distribution.
