Komga is a free, open-source, self-hosted comics and manga server with OPDS and Kobo Sync support. See its features and how it compares to Kavita and Plex.
Komga is a free, open-source, self-hosted media server built specifically for comics, manga, and eBooks, created by developer Gauthier Roebroeck with the project dating back to 2019 and released under the MIT license. Written in Kotlin and distributed as a Docker-friendly Java application, it runs entirely on infrastructure the user controls.
Komga ingests CBZ, CBR, PDF, and EPUB files and organizes them into libraries, collections, and reading lists, with metadata editing for series titles, publishers, genres, and reading order.
Access is provided through a built-in responsive web reader, OPDS and OPDS-PS syndication support for any compatible e-reader app, native Kobo Sync for direct Kobo device access, KOReader Sync for progress synchronization, and compatibility with third-party apps like Mihon on Android.
A full REST API underlies the server, enabling community automation tools, and multi-user access with age and content-label restrictions makes Komga practical for households sharing a single library.
Komga is completely free and open source with no subscription, licensing fee, or paid tier of any kind, funded informally through community donations rather than commercial revenue.
There is no official hosted cloud version; users self-host Komga on their own server, NAS, or home lab hardware, typically via Docker, and support is available through an active community Discord server.
