HolyArrs compared with Sonarr, Radarr, Lidarr, Prowlarr, Bazarr and Seerr

The parts of HolyArrs

Four words used below: a release is one search result that could be downloaded, Pick rules decide which release wins, a Source is a place HolyArrs searches, and a Downloader is your download app.

Each part of HolyArrs, what it does, and the app you may use for that job today

HolyArrs part	What it does	If you use this today
Library: movies	HolyArrs searches your Sources for each movie you want, sends the release your Pick rules choose to a Downloader and files the result in your Library.	Radarr
Library: shows	HolyArrs searches your Sources for each episode you want and files it under its show. Shows and movies share one Library.	Sonarr
Library: music	HolyArrs looks up each artist at MusicBrainz and takes the album list from there. Music has its own Pick rules. New artists start on Lossless first, which keeps the best lossy copy until a lossless one turns up.	Lidarr
Sources	The places HolyArrs searches for releases. It reads Torznab, Newznab and RSS feeds. Some sites need a bridge: see the limits.	Prowlarr or Jackett
Downloaders	HolyArrs hands each release to your download app, follows the download and imports the files when it finishes.	You keep your download app
Requests and Explore	People on your server find a title in Explore and ask for it. The owner or an admin approves, and the title goes into the Library.	Seerr or Overseerr
Subtitles	Set your languages in Settings and see what is missing under Missing subtitles in the Library. Subtitle search is held back in this release.	Bazarr

Your download app and your Plex, Jellyfin or Emby server stay as they are. HolyArrs connects to them.

The numbers

Download size of each Docker image, compressed, for linux/amd64, as Docker Hub shows it. Measured on November 13, 2026.

Sizes are rounded; the total is from the exact byte counts.

Memory: HolyArrs idles at about 95 MB on a fresh install. Your own number depends on your Library.

• 1container
• 6262the one port
• 1sign-in page
• 1backup zip

One container to update, one port to open, one sign-in page to protect and one backup zip to keep. The master key that opens a backup's saved passwords is a separate file; keep it apart from the backups.

What it does not do

• It does not download by itself. HolyArrs hands each release to qBittorrent, Transmission, Deluge, rTorrent, aria2, SABnzbd or NZBGet, then imports what finishes. You need one of them.
• It is young. The first release was in November 2026. Test it with your own setup before you rely on it.
• It has no plugin system yet. Plugins are on the roadmap, not in the app.
• Some sites need a bridge. HolyArrs reads Torznab, Newznab and RSS feeds. A site with no feed of its own needs a bridge such as Prowlarr or Jackett.
• Subtitle search is held back in this release. Languages and the Missing subtitles list work.
• Some helper tools are not supported. Recyclarr, Maintainerr and Cleanuparr do not work with HolyArrs.
• History is not imported. Library folders, titles, Pick rules, Sources and Downloaders come over. The history in your current apps does not.

Try it alongside what you run now

Install HolyArrs next to the apps you run and import your setup. The import only reads your apps: nothing in them changes, they keep running, and your media files never move.

• Keys and passwords never come over. Sources and Downloaders arrive paused, so nothing starts until you type the secret and resume it.
• Imported Downloaders use their own holyarrs category, so HolyArrs never picks up downloads your other apps started.
• Changed your mind? Undo this import removes only what that import added. Your files stay where they are.

Seerr, Overseerr, Bazarr, Prowlarr and Unpackerr can connect to HolyArrs once you switch that on in Settings. How to connect these apps.
