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. With that in mind, below is a list of unofficial mirrors. Depending on the mirror, not all history or modules may be included. For more details, see the "about" link associated with each.
Acquia also maintains a Subversion repository for the Acquia Drupal distribution.
