When to choose each

Calibre-Web if you already use Calibre for library management and want a web frontend for your existing database. It's the most mature option with a large community.

Kavita if your primary use case is manga and comics. It has strong AniList/MyAnimeList integration and a reading UI optimized for sequential art.

Runary if you want built-in readers for all formats (including audiobooks), cross-device position sync, reading analytics, and don't want to depend on Calibre. It's the newest of the three and under active development.

Deployment

All three run as Docker containers. Runary also ships as a fat JAR and native binary for environments without Docker.

# Runary — docker-compose.yml
services:
  runary:
    image: ghcr.io/rygel/runary:latest
    ports: ["9999:9999"]
    volumes: [runary_data:/data]

FAQ

What is the best self-hosted book manager?

It depends on your needs. Calibre-Web is the most mature and integrates with existing Calibre libraries. Kavita is strong for manga and comics with AniList integration. Runary offers built-in readers for all formats (EPUB, PDF, CBZ, audiobooks), cross-device sync, and reading analytics without requiring Calibre.

Does Runary support Kobo sync?

Yes. Runary supports native Kobo sync, KOReader kosync protocol, and OPDS 1.2 + 2.0 for e-reader integration.
