Grimmory is a self-hosted digital library server for ebooks, comics, documents, and audiobooks, deployed via Docker with a web-based interface. It offers metadata enrichment, an in-browser reader, multi-user support with OIDC, OPDS/Kobo/KOReader sync, and automatic import via a watched BookDrop folder.
Use cases
- self-host my ebook collection with a web reader
- manage and read comics (CBZ/CBR) in the browser
- sync reading progress to my Kobo or KOReader
- serve my library to mobile apps over OPDS
- automatically import new books from a watched folder
- send books to my Kindle via email
- share a library with multiple users and per-user progress
- fetch covers and metadata from Google Books and Open Library
When to choose
- you want a single self-hosted app for ebooks, comics, and audiobooks
- you need OPDS, Kobo, and KOReader integration
- you want multi-user libraries with OIDC authentication
- you prefer automatic metadata lookup and rule-based smart shelves
When to avoid
- you only need a lightweight Calibre alternative without a server
- you need DRM-protected store books to work
- you cannot run Docker or a MariaDB database
- you need music or video media management rather than books
