Komga vs Lidarr
A side-by-side editorial comparison of Komga and Lidarr — release velocity, themes, recent moves, and the top alternatives to consider.

Komga vs Lidarr: at a glance
What is Komga?
A mature media server whose releases are format edge cases and Kobo plumbing.
Komga moves between minor releases slowly — 1.24.0 in January, 1.25.0 in late June — with patch releases in between that are almost entirely EPUB parsing fixes. The two features worth naming are solid RAR4 archive support in 1.25.0 and an SSE heartbeat event in 1.24.0. The rest is fixes to EPUB table-of-contents handling, fixed-layout detection, and the Kobo and OPDS2 integration surfaces.
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.

Komga
0.0COLLAB
A mature media server whose releases are format edge cases and Kobo plumbing.
◆ Current state
Komga moves between minor releases slowly — 1.24.0 in January, 1.25.0 in late June — with patch releases in between that are almost entirely EPUB parsing fixes. The two features worth naming are solid RAR4 archive support in 1.25.0 and an SSE heartbeat event in 1.24.0. The rest is fixes to EPUB table-of-contents handling, fixed-layout detection, and the Kobo and OPDS2 integration surfaces.
◆ Where it's heading
The work concentrates where a self-hosted library server actually breaks: malformed EPUBs, archive formats readers assume will just open, and the sync protocols third-party devices speak. Kobo integration keeps taking attention — content restriction enforcement, proxying raw request bodies to the Kobo store — which suggests e-reader compatibility is where the user pressure sits. Translation batches from Weblate appear in most releases.
◆ Prediction
Expect more format-tolerance work on EPUB and archive handling, with the Kobo and KOReader integrations continuing to absorb the fixes that a mature library server accumulates.
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.
