CritiqueBrainz is a repository for Creative Commons licensed music and book reviews. Here you can read what other people have written about an album or event and write your own review!

CritiqueBrainz is based on data from MusicBrainz - open music encyclopedia and BookBrainz - open book encyclopedia. Everyone - including you - can participate and contribute.

CritiqueBrainz is operated by the MetaBrainz Foundation which has a long-standing history of curating, protecting and making music and book data available to the public.

For more information about this project, look at our website.

Changes and other important announcements about the CritiqueBrainz services will be announced on our blog. If you start using our services in any production system, we urge you to follow the blog!

All of our data is available for commercial use. You can find out more about our commercial use support tiers on the MetaBrainz site.

If you are interested in helping out, consider donating to the MetaBrainz Foundation.

If you are interested in contributing code or documentation, please have a look at the issue tracker or come visit us in the #metabrainz IRC channel on irc.libera.chat.
