## What it is
The official server for the MusicBrainz project, providing the musicbrainz.org website, a RESTful web service API, and database tools for the community-maintained music metadata database. It is written in Perl using the Catalyst framework with React-based frontend components and PostgreSQL as the backing store.

## Use cases
- self-host a music metadata database server
- run a local mirror of the MusicBrainz database and API
- build client apps that query music metadata via the MusicBrainz web service
- contribute to or edit the open music encyclopedia
- look up artists, releases, and recordings by music metadata
- replicate the MusicBrainz live data feed into a local PostgreSQL database

## When to choose
- you need to self-host a MusicBrainz instance or mirror the music metadata database
- you want to contribute code to the MusicBrainz website or API
- you need a private instance of the MusicBrainz web service for high-volume lookups

## When to avoid
- you just want to consume MusicBrainz data without hosting it - use the public API or database dumps instead
- you need a tagger application - use MusicBrainz Picard instead
- you are not comfortable maintaining a Perl/Catalyst/PostgreSQL stack
