Mixarr – a music discovery companion for Lidarr/Plex
(thelemmy.club)
Hey everyone,
I'm new here! I wanted to share a music search and discovery tool for Lidarr. It plugs into Spotify, TIDAL, Deezer, Last.fm, MusicBrainz, Plex/Tautulli, Jellyfin, and even some AI recommendations.
GitHub: https://github.com/aquantumofdonuts/mixarr
Website: https://aquantumofdonuts.github.io/mixarr/
What it does:
- Connects to Lidarr and analyzes your existing artists
- Hooks into Spotify, TIDAL, Deezer, Last.fm, MusicBrainz, Plex/Tautulli, and AI services
- Finds related/similar artists, new releases, charts, labels, playlists, etc.
- Gives you a review queue to approve or dismiss discovered artists
- Automatically adds approved artists to Lidarr with the profile you choose
- Has a universal search and discovery interface across all services
- Runs as a web app (Next.js frontend + Express backend) and plays nice with Docker
Why I built it:
I wanted one tool that I could point at my Lidarr library and get a steady stream of relevant artist recommendations.
Basically, make music discovery feel as automated and “infrastructure-y” as the rest of the *arr ecosystem.
Current status:
- Working with Lidarr + Spotify/TIDAL/Deezer/Last.fm/MusicBrainz + Plex/Tautulli
- Has subscriptions for different discovery sources (charts, playlists, related & followed artists, etc.)
- Docker-compose setup available, plus local dev if you prefer
- Early but usable; I’m actively using it myself and iterating
If you try it, I’d love to hear any feedback! Thanks!
EDIT: version 2.0 released today February 10, 2026, with some nice updates
First off thank you so much this is exactly what I've been waiting for.
I looked at the compose file and it doesnt seem to have the base image in there, just the DB and web setup.
I'm not super experienced with docker but would love to deploy this through my dockstarter setup - am I missing something here, is there a way to get it up and running through compose now?
You currently have to build the docker images. Instructions are in the repo
Docker image released here: https://github.com/aquantumofdonuts/mixarr/releases/tag/v1.1.0
I spin it up yesterday and you don’t need to compile anything, it’s quite straightforward.
I released a Docker image. You can get it here: https://github.com/aquantumofdonuts/mixarr/releases/tag/latest
Let me know if you have any issues!
It should work with just docker compose up using the default docker-compose.yml. web and API containers comprise the app, and caddy serves the frontend. Give it a try, let me know if you get stuck!
