Bindery

Website: github.com/vavallee/bindery

Bindery is an acquisition manager for e-books and audiobooks — the Readarr replacement, written from scratch in Go after Readarr was archived in June 2025. You monitor authors, Bindery searches your indexers, sends the chosen release to your download client, and imports the finished book into a library folder with the naming you asked for. It does not serve books to a reader; it feeds a library server such as Calibre-Web Automated or Calibre.

Key Features

• No single metadata dependency: OpenLibrary is the default primary, with Google Books, Hardcover, DNB, Audnex and Audible behind it, and Nasjonalbiblioteket and BnF available as opt-in primaries — all documented public APIs rather than scraped pages.
• Readarr migration: import an existing readarr.db and authors, indexers, download clients and blocklist come across; authors are re-resolved against the working metadata sources.
• E-books and audiobooks: each title holds both formats in independent slots, with separate search, grab and import pipelines and narrator metadata for audio.
• Indexers and clients: Newznab and Torznab indexers queried in parallel and ranked by format quality, edition tags, year and ISBN match; SABnzbd, NZBGet, qBittorrent, Transmission, Deluge and rTorrent are supported.
• Import and organise: auto, move, copy, hardlink or external import modes, naming tokens for author, series, narrator and ASIN, cross-filesystem-safe moves, and an Import page that adopts files you already have.
• Library integration: register imports with Calibre through calibredb or the Bindery Bridge plugin, mirror e-books into a Calibre-Web Automated ingest folder, read an existing Calibre metadata.db, or import an Audiobookshelf library.
• Multi-user: per-user libraries and downloads, an OIDC login, and a requester role for family and friends that can ask for books but not configure anything.
• Light to run: a single Go binary with the React UI embedded, SQLite with no CGO, no external database, a distroless container and a Helm chart, with ARM builds down to a Pi Zero. An OPDS 1.2 catalogue is served for reading apps.

Licence

MIT — free and open source. Some honesty about the category: Bindery automates acquisition, not serving, so it belongs next to a library server rather than instead of one. Its own comparison table puts Calibre-Web and Audiobookshelf in the “serving an already-curated library” camp, downstream of Bindery. It is usenet- and torrent-oriented, so what you can find depends entirely on the indexers you have access to.
