Calibre-Web

Calibre-Web is a lightweight web application that exposes your Calibre eBook database through a browser-friendly interface. It lets users browse, search, download, and read books from an existing Calibre library, with multi-user access controls and optional email/Kindle delivery.

Key Features

• Integrates with an existing Calibre database (metadata.db) and library folder structure
• Responsive web UI to browse by author/series/tags, view metadata, covers, and formats
• Built-in web reader for supported formats (commonly EPUB) and direct downloads for available formats
• Full-text search and filtering across library metadata
• Multi-user support with roles/permissions (e.g., admin vs. regular users) and per-user settings
• OPDS catalog support for e-reader/mobile catalog clients
• Optional “send to e-reader”/email delivery via SMTP (commonly used for Kindle)
• Basic library management features (depending on configuration), such as editing metadata and uploads

Use Cases

• Host a private household eBook library accessible from any device on your network
• Provide a small community/library portal with accounts, browsing, and OPDS feeds
• Deliver purchased/public-domain books to e-readers via email while keeping the library centralized

Limitations and Considerations

• Designed around Calibre’s library/database; best results require a properly maintained Calibre library
• Feature scope is focused on web access/sharing rather than replacing the full Calibre desktop app

Calibre-Web is well-suited for turning a Calibre-managed collection into a convenient, multi-user web library. It emphasizes simple deployment, an accessible UI, and compatibility with common e-reader workflows (downloads, OPDS, and email delivery).
