MusicBrainz is made up of, and works with, several different components: the MusicBrainz Server, MusicBrainz Database, web service (and related client libraries), and lastly third party applications/services. Bug tracking is done centrally at http://tickets.musicbrainz.org/.
Our development timeline records major releases and developer summits.
The MusicBrainz Server is a GPLv2 licensed open source project. It's written primarily in Perl and makes use of Catalyst, Moose, and Template Toolkit. Development on the server was started in 2000 and has had many contributors over the years.
The Picard source code is available at https://github.com/musicbrainz/picard.
- Development team
Our developers are primarily based in North America and Europe. The easiest way to get in touch with them is via IRC in #metabrainz on irc.freenode.net.
- Third-party developers
We are proud to have a third-party development community that builds applications and services that utilize or build upon the data that we provide. Most of these third-party projects use one our client libraries to query our web service, others set up their own database.
