What is it?

Stump is a self-hosted server for organizing and reading comics, manga, and digital books. It serves your library over OPDS v1.2 and v2.0, so compatible e-reader and reading apps can browse and download books from it. The web interface includes built-in readers for EPUB, PDF, CBZ/ZIP and CBR/RAR files.

The server supports multiple user accounts with permissions, age restrictions and other access controls, plus OIDC sign-in. EPUB books can be annotated and highlighted. Kobo and KoReader sync integrations are included for keeping reading progress across devices.

Stump is written in Rust with Axum and SeaORM on the backend and React for the UI, and it is distributed through Docker and pre-built binaries. The project is still in beta, and the maintainer notes there are no guarantees against breaking changes before a 1.0 release.
