Immich vs Prowlarr: at a glance
What is Immich?
Immich's 3.4 candidate adds passkeys and built-in backups.
Immich is in its v3.4 release-candidate cycle. rc.1 added passkey sign-in, built-in backups using restic's parallel scan, JPEG XL decoding and encoding, mobile tags and workflow filters, plus security fixes around shared links, partner timelines, symlinks and OAuth cookies; rc.2 on 4 November contains bug fixes only. The v3.3 cycle before it brought people management, TensorRT-RTX acceleration and lighter ML models.
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.

Immich
5.0COLLAB
Immich's 3.4 candidate adds passkeys and built-in backups.
◆ Current state
Immich is in its v3.4 release-candidate cycle. rc.1 added passkey sign-in, built-in backups using restic's parallel scan, JPEG XL decoding and encoding, mobile tags and workflow filters, plus security fixes around shared links, partner timelines, symlinks and OAuth cookies; rc.2 on 4 November contains bug fixes only. The v3.3 cycle before it brought people management, TensorRT-RTX acceleration and lighter ML models.
◆ Where it's heading
Each minor now runs through three or four public candidates before release. The 3.x line moved from discovery features (search, faces, memories) toward running Immich safely as a household's primary photo store: sharing controls, authentication and backups.
◆ Prediction
v3.4.0 stable should follow after one or two more candidates. Restoring from the new backups inside Immich is the natural follow-up if it isn't already part of 3.4.
Prowlarr
5.0COLLAB
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.
