Where each falls short
The honest trade-offs — what you give up with each, versus the proprietary tools they replace.
koel
- Requires PHP runtime and a relational database, adding operational overhead vs. single-binary alternatives.
- No native mobile apps; mobile access relies on third-party Subsonic clients.
- No algorithmic recommendations or social/collaborative features like Spotify.
- Podcast support is absent; music library files only.
Lidarr
- Requires external download client (SABnzbd, qBittorrent, etc.) to function
- Indexer configuration can be complex for newcomers
- Not a streaming server itself; must pair with a music server
Bottom line
