Prowlarr vs Radarr: at a glance
What is Prowlarr?
Prowlarr 3.0 pre-release moves to .NET 10 and requires Postgres 15
Prowlarr, the indexer manager for the *arr apps, ships patch releases every one to three weeks. The 2.6–2.7 line added Trusted Networks, hostname validation and wildcard IPs in Allowed Hosts. A 3.0.0 pre-release on the develop branch now moves the runtime to .NET 10 and Node 24, raises the minimum Postgres version to 15 and adds reflink support for ZFS.
What is Radarr?
Radarr's 7.0 pre-release line now shows every audio and subtitle stream per file.
Radarr's 7.0 pre-release line is on its second build. 7.0.0 moved the app to .NET 10 and added OIDC login, PEM certificates and Trakt Smart List imports. 7.0.1 follows with media info that lists every audio and subtitle stream, full Transmission label support and clearer import-failure messages. The main branch is still on 6.4.4.

Prowlarr 3.0 pre-release moves to .NET 10 and requires Postgres 15
◆ Current state
Prowlarr, the indexer manager for the *arr apps, ships patch releases every one to three weeks. The 2.6–2.7 line added Trusted Networks, hostname validation and wildcard IPs in Allowed Hosts. A 3.0.0 pre-release on the develop branch now moves the runtime to .NET 10 and Node 24, raises the minimum Postgres version to 15 and adds reflink support for ZFS.
◆ Where it's heading
The project is pairing small indexer fixes on the stable branch with a platform refresh on develop. The 3.0 work is mostly runtime and database floor changes rather than new user features, so the jump is about keeping the stack current.
◆ Prediction
Expect further 3.0 pre-releases before a stable 3.0, with Postgres users below version 15 needing to upgrade first; the entries do not show a release date.
Radarr
5.0COLLAB
Radarr's 7.0 pre-release line now shows every audio and subtitle stream per file.
◆ Current state
Radarr's 7.0 pre-release line is on its second build. 7.0.0 moved the app to .NET 10 and added OIDC login, PEM certificates and Trakt Smart List imports. 7.0.1 follows with media info that lists every audio and subtitle stream, full Transmission label support and clearer import-failure messages. The main branch is still on 6.4.4.
◆ Where it's heading
The 7.0 cycle pairs a platform upgrade with deeper file-level detail: media info, import diagnostics and download-client labels. The media info migration was split into batches to avoid running out of memory, which shows the team is hardening the upgrade path for large libraries before a stable release.
◆ Prediction
More 7.0.x pre-release builds with import and media info fixes are likely before 7.0 reaches the main branch; the entries do not show a date for that promotion.
