Kapowarr is a web-based application for building and managing a digital comic book library, designed in the style of the *arr ecosystem. It helps you organize volumes and issues with rich metadata, and automates searching, downloading, and post-processing of comic files.

Key Features

  • Import existing comic libraries and map volumes to folders
  • Fetch and manage metadata for volumes and issues (commonly via ComicVine)
  • Automated bulk actions such as searching monitored content for entire volumes
  • Manual search and selection for fine-grained control over downloads
  • Post-processing: rename, move, extract archives, and organize files to your preferred structure
  • Supports multiple issue types and collections (e.g., TPBs, one-shots, hardcovers)
  • Familiar *arr-style web UI and configurable automation settings

Use Cases

  • Maintain a structured, metadata-rich archive of digital comics
  • Automate acquisition and organization of ongoing series as new issues release
  • Clean up inconsistent filenames and folder layouts across an existing collection

Limitations and Considerations

  • Metadata and some automation depend on third-party providers and may be affected by rate limits or provider changes

Kapowarr is well-suited for anyone who wants an automated, *arr-like workflow for comics while keeping full control over naming, folders, and download decisions. It combines library management, metadata, and post-processing to keep a comic collection consistently organized.
