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.
