  • Metadata handling (title/author/series/tags) and cover management
  • Full-text and/or fielded search across your collection
  • Built-in web reader for supported ebook formats
  • OPDS catalog support for connecting external reading apps
  • Multi-user support with authentication and user-specific experience

Komga is well-suited for anyone maintaining a local comics/manga collection who wants a modern library UI, a solid web reader, and OPDS access for external reading apps. Its API and user/library permissions make it practical for personal, family, or small community setups.
