Debsources now in sources.debian.org
Debsources is a web application for publishing, browsing and searching an unpacked Debian source mirror on the Web. With Debsources, all the source code of every Debian release is available in https://sources.debian.org, both via an HTML user interface and a JSON API.
This service was first offered in 2013 with the sources.debian.net instance, which was kindly hosted by IRILL, and is now becoming official under sources.debian.org, hosted on the Debian infrastructure.
This new instance offers all the features of the old one (an updater that runs four times a day, various plugins to count lines of code or measure the size of packages, and sub-apps to show lists of patches and copyright files), plus integration with other Debian services such as codesearch.debian.net and the PTS.
The Debsources Team has taken the opportunity of this move of Debsources onto the Debian infrastructure to officially announce the service. Read their message as well as the Debsources documentation page for more details.
