What is it?

Komga is a media server for organizing and reading comics, manga, BDs, magazines and eBooks. It scans your library folders and presents libraries, series and books through a responsive web interface that works on desktop, tablet and phone. A built-in webreader supports several reading modes.

Beyond browsing, Komga handles metadata editing, embedded metadata import, collections and read lists, and multi-user access with per-library permissions, age restrictions and label restrictions. It also includes duplicate file and duplicate page detection, and can import ComicRack cbl read lists.

For other clients, Komga exposes a REST API, OPDS v1 and v2 feeds, Kobo Sync for Kobo eReaders and KOReader Sync. It is written in Kotlin on Spring Boot and is distributed as a binary release and a Docker image.
