Kapowarr

Website: casvt.github.io/Kapowarr

Kapowarr builds and manages a comic book library, and it is designed to sit in the *arr family next to Sonarr and Radarr. You add a volume, map it to a folder, and Kapowarr downloads the issues, renames and moves the files where you want them and converts archives into the format you prefer. Metadata comes from ComicVine, which needs a free ComicVine API key during setup.

Key Features

• Search Monitored: one click downloads every missing issue of a volume; Manual Search lets you pick individual releases yourself.
• Library Import: point Kapowarr at existing files and it proposes ComicVine matches for each one, which you can correct before applying.
• Download clients: built-in clients for the services GetComics uses, including Mega and Pixeldrain, with credential support for paid accounts and Remote Path Mappings for containers and separate machines.
• File handling: downloads are moved to the right folder and renamed using a pattern you define, and archive files can be extracted and their contents renamed.
• The familiar interface: the *arr look and workflow — a volumes grid with poster covers, monitored state and per-volume issue counts.
• API: documented API for scripting and integration, in addition to the web UI.

Licence

GPL-3.0 — free and open source. It manages and downloads comics rather than serving them to a reader, so pair it with a library server: Kavita or Komga both read the folders Kapowarr organises.
