Comic Library Utilities (CLU) is a self-hosted comic library manager that converts, repairs, tags, downloads, and reads your entire comic collection from one web interface. Convert whole folders or libraries from CBR to CBZ in bulk, turn PDFs into CBZ with JPEG or WebP output, and rename thousands of files to one consistent pattern without touching a terminal. Open any CBZ in the browser editor to reorder pages, add or delete images, crop covers, split merged multi issue archives, and adjust contrast and brightness issue by issue. Write ComicInfo.xml from Metron, ComicVine, Grand Comics Database, AniList, MangaDex, MangaUpdates, or Bedetheque, then bulk apply tags across a directory with review before saving and a history log that can revert any change. Browse your library by publisher, series, or folder, read page by page in the built in reader that remembers your place, and follow weekly release calendars with a pull list and Wanted tracker for issues you do not own yet. Download new issues from Direct Download sources, Usenet through Newznab indexers with SABnzbd or NZBGet, and DC++, while folder monitoring unpacks, converts, renames, and files new arrivals automatically. Add Reader, Clerk, and Store Owner accounts with per folder permissions, publish OPDS feeds for reader apps, and sync reading history with Komga. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. GPL-3.0 licensed.
