Komga is a media server for managing collections of comics, manga, bandes dessinées, magazines and ebooks. It provides a web interface for browsing and reading material stored on a personal server.
The application organises books into libraries and series, allowing readers to navigate collections without manually opening individual files. It can extract embedded metadata and provides tools for correcting or extending information associated with books.
Komga is particularly useful for comic collections that contain many issues or volumes. It provides facilities for organising reading lists, identifying duplicate material and accessing books from other reading applications.
The server also supports dedicated ebook devices and external clients through catalogue and synchronisation interfaces.
This is free and open source software.
