Komga vs Readarr
A side-by-side editorial comparison of Komga and Readarr — release velocity, themes, recent moves, and the top alternatives to consider.
Komga vs Readarr: 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 Readarr?
Six releases of small fixes and translations, then nothing since June 2025.
Readarr's last six entries run from March to June 2025 and are uniformly small: a truncated root-folder path, remote image links for posters and covers, NLog message templating, disabled SelectInput options, Weblate translation batches. Every entry opens with the same instructions about switching to the develop branch and not updating inside a running Docker container. Nothing in this window adds capability, and no entry has appeared in over a year.

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.
Readarr
0.0COLLAB
Six releases of small fixes and translations, then nothing since June 2025.
◆ Current state
Readarr's last six entries run from March to June 2025 and are uniformly small: a truncated root-folder path, remote image links for posters and covers, NLog message templating, disabled SelectInput options, Weblate translation batches. Every entry opens with the same instructions about switching to the develop branch and not updating inside a running Docker container. Nothing in this window adds capability, and no entry has appeared in over a year.
◆ Where it's heading
The pattern is a project in caretaker mode: auto-generated commit lists, incremental UI corrections, and internal work like using ReflectionOnly types to avoid loading assemblies unnecessarily. Volume held steady at roughly one release every one to two weeks until it stopped entirely. The entries themselves give no reason for the halt.
◆ Prediction
The changelog offers no signal of resumed development; without new entries there is nothing here to project forward beyond the fact that the feed went quiet after 0.4.18.
