Mylar3 is a web-based comic book library manager and automation tool focused on building and maintaining a local digital comics collection. It tracks series you want, monitors for new issues, and can automate acquisition via supported download clients, then organizes files and metadata.

Key Features

Library management for comic series and issues with a browser-based UI
“Wanted” monitoring: track series and automatically look for missing/new issues
Metadata and artwork fetching (comic/series info, covers) and post-processing
File organization tools such as renaming and folder structuring for consistent libraries
Integration with download clients (commonly used alongside Usenet/torrent workflows)
Import/rescan capabilities to match existing files to series/issues

Use Cases

Automatically keep up with ongoing comic series and pull new issues as they release
Clean up and standardize filenames/folders for large existing comic libraries
Maintain metadata and cover art to improve browsing in comic readers/servers

Limitations and Considerations

Project capabilities depend on external indexers/providers and download client setup
Matching/metadata accuracy can vary with naming quality and source metadata

Mylar3 is suited to users who want a “set-and-forget” workflow for managing comics, combining tracking, automation, and library hygiene. It works best when paired with a reliable download stack and a well-structured storage layout.
