Drupal is a free and open-source web content management system (CMS) written in PHP and distributed under the GNU General Public License. Drupal provides an open-source back-end framework for at least 14% of the top 10,000 websites worldwide and 1.2% of the top 10 million websites—ranging from personal blogs to corporate, political, and government sites. Drupal can also be used for knowledge management and for business collaboration.

We the People, launched by the Obama administration on September 22, 2011, is a defunct section of the whitehouse.gov website used for petitioning the administration's policy experts. Petitions that reached a certain threshold of signatures were reviewed by Administration officials who in most instances would subsequently provide an official response. Legal proceedings in the United States were not subject to petitions, rather, the site served as a public relations mechanism for the presidential administration to provide a venue for citizens to express themselves. On August 23, 2012, the White House Director of Digital Strategy Macon Phillips released the source code for the platform. The source code is available on GitHub, and lists both public domain status as a work of the United States federal government and licensing under the GPL v2.
