KOmpanion

Self-hosted bookshelf backend tightly coupled with the KOReader e-reader app.

Webfreeglobal

KOmpanion is a self-hosted library backend built specifically to pair with the KOReader e-reader app. It lets a user upload and browse their bookshelf, download books over OPDS, and sync reading progress and stats across devices, without trying to be a reader or format converter itself. It is aimed at KOReader users who want their own server for book storage and progress sync instead of a cloud service.
