Readarr vs LazyLibrarian: Which Book Manager?

Quick Verdict

Update (June 2025): Readarr’s GitHub repository has been archived — no further development is planned. Existing installs work fine, but LazyLibrarian is now the only actively maintained option between the two.

For existing *arr stack users, Readarr still works well and uses the same UI and workflow you already know. LazyLibrarian is more feature-rich for book-specific tasks — magazine support, audiobook conversion, Goodreads integration — and is now the safer long-term choice given Readarr’s archived status.

Overview

Both tools automate ebook discovery and downloading. You add authors or books, and the software monitors indexers for new releases, grabs them, and organizes your library.

Readarr is the *arr-family book manager built by the Servarr team. It follows the same patterns as Sonarr (TV) and Radarr (movies) — quality profiles, indexer integration via Prowlarr, and automatic importing. It focuses on ebooks and audiobooks.

LazyLibrarian is an older, Python-based book manager that predates Readarr. It pulls metadata from Goodreads and LibraryThing, monitors downloads, and can handle ebooks, audiobooks, and magazines. It has more book-specific features but a less polished interface.

Installation Complexity

Both are single-container deployments.

Readarr:

    container_name: readarr
    environment:

    restart: unless-stopped

LazyLibrarian:

Readarr is faster to configure if you already run Prowlarr — indexers sync automatically. LazyLibrarian requires manual indexer setup but offers optional Docker mods for Calibre integration and audiobook conversion (FFmpeg).

Note: LazyLibrarian uses rolling version tags (version-dada182d format) rather than semantic versioning. Pin to a specific commit hash tag for reproducibility.

Readarr benefits from the broader *arr ecosystem — shared knowledge, similar workflows across all *arr apps, and a large Discord community. LazyLibrarian has a dedicated but smaller community.

Use Cases

Choose Readarr If…

  • You already run Sonarr, Radarr, and Prowlarr
  • You want a consistent UI across all your media managers
  • You prefer the *arr-style quality profiles and automation
  • Ebooks and audiobooks are your only book media types
  • You want native Prowlarr indexer sync

Choose LazyLibrarian If…

  • You manage magazines alongside ebooks
  • Goodreads integration is important to your workflow
  • You want built-in Calibre conversion support
  • You don’t run the *arr stack and want a standalone book manager
  • Audiobook format conversion (via FFmpeg mod) is needed

Final Verdict

*For existing arr stack users already running Readarr, keep it. The consistent interface and native Prowlarr integration still work well. But since Readarr was archived in June 2025, don’t expect bug fixes or new features.

For new setups, LazyLibrarian is the safer bet. It’s actively maintained, supports magazines alongside ebooks, and has deeper Goodreads integration and Calibre conversion. The interface is older, but you’re choosing software that will continue receiving updates.

Also consider Calibre Web Automated if your focus is ebook management with automatic downloading — it’s actively developed and growing fast.

FAQ

Can I run both Readarr and LazyLibrarian?

Yes, but there’s no real benefit. They’d compete for the same downloads and create duplicate library entries. Pick one based on your needs.

Does Readarr support Calibre library integration?

Readarr can import books into a Calibre library via Calibre Content Server. It’s not as deep as LazyLibrarian’s integration with the Calibre Docker mod, but it works for basic import workflows.

Is LazyLibrarian still actively maintained?

Yes. Development continues on GitLab with frequent commits. The LinuxServer.io image is updated regularly. It’s a community-driven project without formal release cycles — updates are rolling.
