Calibre Web (Automated)
$9.00 / month with a 7-day free trial and a $1.00 sign-up fee
Self-hosted Calibre library web UI with automated ingestion, format conversion, and send-to-Kindle/Kobo.
A managed Calibre Web Automated instance hosted on ElfHosted. Browse, read, and download your Calibre ebook library via a modern web UI — plus an automated ingestion pipeline that processes new books dropped into an inbox folder, converts formats (EPUB→KEPUB for Kobo, etc.), and updates metadata without manual Calibre desktop sessions. OPDS support for Kindle and Kobo. Bring your existing Calibre library or start fresh.
The web UI your Calibre library has always needed — without the VNC desktop, without the manual "hit Calibre to add a book" step, and without a home server that needs babysitting.
What is Calibre Web Automated?
Calibre Web Automated (CWA) is an enhanced fork of Calibre-Web — the well-established browser-based front-end for Calibre library databases. Where vanilla Calibre-Web gives you a read-only-ish web view over your existing Calibre DB, CWA adds:
- An automated ingestion pipeline: drop new ebook files into a watched inbox folder and CWA processes them into the library, fetches metadata, and converts formats — no Calibre desktop session required.
- Automatic format conversion (EPUB→KEPUB for Kobo, EPUB→MOBI for older Kindles, etc.) on ingest.
- A clean, mobile-usable web UI for browsing, reading, and downloading — the standard Calibre GUI requires VNC and is unusable on phones.
This is a managed CWA instance on ElfHosted, pre-configured with mounts, TLS, and SSO. Bring your existing Calibre library database (or start fresh), mount your ebook storage, and your library is accessible from any browser or OPDS client.
Key Features
- 📥 Automated ingestion: drop EPUB, MOBI, PDF, AZW3, or CBZ files into an inbox folder; CWA processes them into the Calibre DB, fetches metadata, and converts formats automatically.
- 🔄 Format conversion: auto-converts on ingest — EPUB→KEPUB for Kobo, format normalisation for Kindle. No manual Calibre desktop conversion step.
- 📚 Full Calibre database: authors, series, tags, custom columns, ratings, reading lists — the complete Calibre metadata model, browsable in a modern web UI.
- 📡 OPDS catalog: Kindle Paperwhite and Kobo devices browse and download directly via OPDS; Koreader and other OPDS clients supported.
- ☁️ Send-to-Kindle / Send-to-Kobo: one-click delivery to your linked device email (Kindle) or directly (Kobo via KFMon/Nickel).
- 👥 Multi-user: per-user shelves, reading lists, and download history with role-based access.
- 🔓 FOSS: open-source, no upstream subscription required.
- 🔄 Updates handled: ElfHosted keeps CWA current.
Calibre Web vs Kavita — Library Management vs Active Reading
Both serve ebooks from a self-hosted server. The difference is their primary role:
- Calibre Web Automated (this product) — front-end on a Calibre database. Best for users who already manage their library in Calibre (metadata, covers, custom columns, format conversion). The automated ingestion pipeline makes it the drop-and-done choice for adding books. Strong Kindle/Kobo delivery support.
- Kavita — purpose-built reading server, not tied to a Calibre database. Better in-browser reading experience; handles comics and manga alongside ebooks. The right choice if you want to read actively rather than manage a library.
Many users run both: CWA to manage and deliver books to their Kindle/Kobo, Kavita to read actively in the browser. They're complementary, not competing.
Why Run Calibre Web Automated on ElfHosted?
Running Calibre-Web locally is fine — until you want OPDS available on your Kindle away from home, or you want the automated ingestion pipeline running 24/7 without a home server staying on. ElfHosted handles all of that:
- HTTPS on your own ElfHosted subdomain — Kindle and Kobo OPDS work from anywhere.
- Library storage via rclone-mounted cloud (Google Drive, OneDrive, S3, B2) — or upload directly.
- Automated ingestion runs continuously in the cloud — no home server needed.
- SSO on the web UI.
- Updates roll out without you touching anything.

Frequently Asked Questions
How do I run Calibre Web without self-hosting it?
Add it to your ElfHosted subscription — this product is a managed Calibre Web Automated instance, pre-configured with TLS and SSO. No Docker, no reverse-proxy, no VNC required.
What does "Automated" mean?
CWA adds an automated ingestion pipeline to vanilla Calibre-Web. Drop new ebook files into a watched inbox folder; CWA picks them up, fetches metadata (title, author, cover), converts formats as needed (e.g., EPUB→KEPUB for Kobo), and adds them to your Calibre database — without you opening the Calibre desktop app.
Do I need an existing Calibre library?
No. You can start with an empty database and build your library by dropping books into the inbox. Or import an existing Calibre library database and your ebook files.
Does it work with Kindle?
Yes. CWA supports send-to-Kindle via email delivery, and exposes an OPDS catalog that the Kindle browser and third-party apps can browse. Older Kindles that support MOBI can have files auto-converted on download.
How is this different from Kavita?
Kavita is a purpose-built reading server — optimised for in-browser and OPDS reading of ebooks, manga, and comics. CWA is a front-end on a Calibre database — better for library management, format conversion, and Kindle/Kobo delivery. Many users run both: CWA to manage and deliver, Kavita to read.
Can I manage my Calibre metadata from the web UI?
Basic edits (title, author, series, tags) yes. Complex Calibre operations (mass metadata plugins, full custom column management) still need Calibre desktop pointed at the same database file.
Hosted Calibre Web Automated is the self-hosted ebook library that manages itself — automated ingestion, format conversion, and Kindle/Kobo delivery, all without touching the Calibre desktop app. Bring your library; we run the server.
