Lidarr vs Prowlarr
A side-by-side editorial comparison of Lidarr and Prowlarr — release velocity, themes, recent moves, and the top alternatives to consider.
Lidarr vs Prowlarr: at a glance
What is Lidarr?
Lidarr's release notes still tell you not to update Radarr — the fork's seams are showing.
Lidarr publishes auto-generated pre-release builds every few weeks, each carrying a handful of commits. The recent ones add rate limiting to Spotify lookup endpoints, fix basic auth and cookie reuse for qBittorrent, pull in Weblate translation updates and bump ImageSharp and MailKit. The boilerplate at the top of every entry warns against updating Radarr inside an existing container — text inherited from the upstream project and never changed.
What is Prowlarr?
A steady indexer-maintenance cadence: fixes, definitions, translations, repeat.
Prowlarr ships every week or two off the develop branch, and the entries are consistently small: indexer definition corrections, parsing fixes, dependency bumps and Weblate translation batches. The only user-facing addition in this window is showing indexer-specific categories in search. Every entry opens with the same boilerplate about switching update branches, which is the feed's own shape rather than news.
Lidarr vs Prowlarr: editorial side-by-side
Lidarr
5.0COLLAB
Lidarr's release notes still tell you not to update Radarr — the fork's seams are showing.
◆ Current state
Lidarr publishes auto-generated pre-release builds every few weeks, each carrying a handful of commits. The recent ones add rate limiting to Spotify lookup endpoints, fix basic auth and cookie reuse for qBittorrent, pull in Weblate translation updates and bump ImageSharp and MailKit. The boilerplate at the top of every entry warns against updating Radarr inside an existing container — text inherited from the upstream project and never changed.
◆ Where it's heading
This is a project maintained rather than developed. Version numbers advance through build counts more than features, one release in this window contains nothing but a version bump, and the substantive work is defensive: staying within third-party rate limits, keeping torrent client authentication working, absorbing dependency updates. The metadata providers it depends on are where the pressure shows.
◆ Prediction
Expect continued small builds driven by external breakage — torrent client authentication changes and metadata provider limits are the two recurring sources here. The rate limiting added for Spotify suggests provider throttling is an active problem, so more of the same is the likeliest next move.
Prowlarr
5.0COLLAB
A steady indexer-maintenance cadence: fixes, definitions, translations, repeat.
◆ Current state
Prowlarr ships every week or two off the develop branch, and the entries are consistently small: indexer definition corrections, parsing fixes, dependency bumps and Weblate translation batches. The only user-facing addition in this window is showing indexer-specific categories in search. Every entry opens with the same boilerplate about switching update branches, which is the feed's own shape rather than news.
◆ Where it's heading
The value being shipped is upkeep of the indexer catalogue — PreToMe categories, M-Team category updates, MyAnonamouse author name handling, IPTorrents query parameters. That is the actual product for an indexer manager, but it means the release history reads flat: no architectural change, no new integration surface, no shift in what Prowlarr does. Version numbers move faster than capability.
◆ Prediction
Expect the same rhythm — per-indexer definition fixes and dependency bumps cut every one to two weeks — with any notable change arriving as a small search or UI addition rather than a release theme.
