What is Lidarr?

Lidarr brings the Sonarr approach to music. You follow artists, and it watches RSS feeds for new albums and tracks, sends releases to SABnzbd, NZBGet or a torrent client, then sorts and renames the files. It can scan an existing library and fetch missing tracks, upgrade quality when a better release appears, retry failed downloads and handle multi-album releases. Kodi and Plex receive notifications and library updates. It runs on Windows, Linux, macOS and Raspberry Pi.

Good fit if

  • You maintain a large music library and want new releases from your artists added automatically.
  • You already use Sonarr or Radarr and want the same workflow for albums.

Look elsewhere if

  • You want to fix tags and organize files you already have: Beets.
  • You need a server to stream the music: Navidrome.

Before you adopt it

Lidarr is GPL-3.0, has no paid parts, and requires contributors to sign a CLA. The README warns that its metadata server is rebuilding its cache, which currently affects adding artists and library imports. Ready-made packages cover the three desktop systems. Make sure your download sources are legal where you live.
