BookOrbit serves ebooks, PDFs, comics and audiobooks, with reading-position and annotation sync across its web interface and supported devices. It offers OPDS and OIDC integration and deployment with Docker and PostgreSQL. The current repository requires a reliable local filesystem and explicitly does not support network filesystems such as SMB or NFS. Older installation examples should not override that limitation. Users should also review the AGPL license’s additional terms and the evolving third-party API before integrating it.
