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
Yeah, I wasn't trying to say SQLite is universally better. I shouldn't have said best option, I really meant best default. I don't think the majority of users are running a central db, most will just spin-up docker compose files for each service and end up with multiple SQL versions running.
I have had this issue, but it was always easily recoverable. I haven't had the same issues with backups, although a lot of the software I use that's running SQLite has a builtin backup feature, then I just backup that directory to a cloud service.
When an app is using an ORM already, I think they might as well make sure it supports both SQLite and a hosted DB like Postgres
Yeah that's true, in the case of just running a premade compose file sqlite is the better choice for sure
