Readarr vs Prowlarr: at a glance
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.
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.

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.
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.
