Atsumeru

Atsumeru is a self-hosted media server designed to manage and serve manga, comics and light novels. It provides library organization, metadata editing and synchronization with native desktop and mobile clients.

Key Features

• Library management for series and archives with support for categories, autocategories and metacategories
• Native clients and manager apps for Windows, Linux, macOS and Android with two-way reading history sync
• Supports archive and ebook formats: CBZ, CBR, CB7, PDF, ePub (limited), FB2 (limited) and DjVu
• Metadata editing with automatic import from ComicInfo.xml and book_info.json and ability to parse from supported catalogs
• Multi-user support with separate histories and access-control features including role-based access
• REST API with OpenAPI/Swagger documentation for integration and automation
• Docker image available for containerized deployment and a runnable JAR for manual setups
• Batch download support to download whole series for offline reading

Use Cases

• Personal library: host and organize a private collection of manga, comics and light novels with rich metadata
• Small groups or household sharing: provide multi-user access with separate reading histories and access controls
• Syncing reading progress across desktop and mobile apps while maintaining local control of content

Limitations and Considerations

• ePub and FB2 support are available but have known limitations in parsing and rendering compared to archive formats
• Runs on the Java platform and requires a Java runtime for the standalone JAR deployment; resource usage scales with library size

Atsumeru is focused on providing a privacy-friendly, metadata-rich media server tailored for sequential reading formats. It is suitable for users who want local control over their manga/comics/light novel collections and integration with native reading clients.
