The *arr for comics — automated comic-volume tracking, downloading, and renaming for Komga or Kavita libraries.
A managed Kapowarr instance hosted on ElfHosted. Add a comic volume, Kapowarr watches for new issues, finds them via direct or third-party sources (MediaFire, Mega, etc.), downloads, extracts, renames, and drops them into the folder Komga or Kavita watches. Same intuitive *arr UI as Sonarr and Radarr — comics-arr is what it sounds like.
Sonarr for TV, Radarr for movies, Lidarr for music, Readarr for ebooks — Kapowarr is the comics one. Same UI patterns, same automation model, applied to comic volumes and issues.
What is Kapowarr?
Kapowarr is a self-hosted comics library manager modelled directly on the *arr family (Sonarr, Radarr, Lidarr, Readarr). Add a comic volume — say, all of Saga or The Walking Dead — and Kapowarr tracks new issues, finds them via direct downloads or third-party file hosts, automatically downloads, extracts, renames, and files them into your comics library.
The output drops into a folder your comics reading server (Komga or Kavita) watches, so new issues appear in your reader the moment they're available.
Key Features
- 📦 Volume tracking: add a comic volume, Kapowarr watches for new issues — no manual searches.
- 🔎 Manual + automatic search: "Search Monitored" grabs an entire volume in one click; "Manual Search" lets you pick a specific release when you want control.
- 🌐 Multi-source downloads: direct downloads plus support for third-party file hosts (MediaFire, Mega, etc.).
- 📥 Library import: bring an existing comic library; Kapowarr scans, identifies, and matches against its metadata.
- 🏷️ Rich metadata: volume- and issue-level metadata pulled automatically.
- 📂 Automated file management: renames and moves downloaded files into your preferred folder structure — Komga/Kavita can scan immediately without manual intervention.
- 🗜️ Zip handling: automatically extracts and renames zip contents to clean CBZ format.
- 🎯 Familiar *arr UI: if you've used Sonarr or Radarr, you already know how to drive Kapowarr.
- 🔄 Updates handled: ElfHosted keeps Kapowarr current.
Where Kapowarr Sits in the Comics Stack
Kapowarr is automation, not a reader — same as Sonarr isn't a TV player. Pair it with a comics reading server:
- Komga — comics/manga specialist with strong series-and-volume metadata. The natural pair for Kapowarr if your library is mostly comics.
- Kavita — all-rounder for mixed libraries (ebooks + comics + manga). Works equally well as a Kapowarr target if your library is mixed.
Kapowarr drops new issues into the watched folder; Komga or Kavita scans and surfaces them in the reader without you doing anything. Same model as Sonarr → Plex/Jellyfin for TV.
Why Run Kapowarr on ElfHosted?
Kapowarr is fine to self-host — until it needs to share a folder with your comics reader, run reliably 24/7 to catch new issues, and have direct-download throughput that doesn't choke your home connection. ElfHosted handles all of that:
- Pre-wired filesystem sharing with your ElfHosted Komga or Kavita — no path-mapping, no NFS troubleshooting.
- Symmetric server bandwidth — direct-download sources hit Kapowarr at full speed.
- HTTPS on your own ElfHosted subdomain.
- SSO on the web UI.
- Updates roll out without you touching anything.

Frequently Asked Questions
How do I run Kapowarr without self-hosting it?
Add it to your ElfHosted subscription — this product is a managed Kapowarr instance pre-wired to share storage with your ElfHosted comics reader.
Is Kapowarr like Sonarr but for comics?
Yes — that's the design. Same UI patterns, same monitor-and-grab automation model, same renaming-and-filing logic, applied to comic volumes and issues.
Where do the comics get read?
In Komga or Kavita. Kapowarr drops new issues into a folder either reader scans; the comic appears in the reader automatically.
Do I need an existing comic library?
No, but you can import one if you have it. Kapowarr scans existing CBZ/CBR collections and matches issues against its metadata so you don't lose what you've already collected.
What sources does Kapowarr support?
Direct downloads (HTTP) plus third-party file hosts (MediaFire, Mega). It does not currently include built-in torrent or Usenet handling — that distinguishes it from Sonarr/Radarr's indexer model.
Does Kapowarr include any comics?
No. Kapowarr is the automation engine — bring your own library or sources.
Hosted Kapowarr is the comics-arr — the missing piece that completes a Sonarr/Radarr/Lidarr/Readarr/Kapowarr stack. Pair with Komga or Kavita for the reader, let Kapowarr handle the library, and your new issues land in your comics reader without you touching a thing.
