Self-host librarr

Librarr is a self-hosted search and download manager for books, audiobooks, and manga written in Go. It searches configured indexers (Prowlarr, OPDS catalogs, public APIs, Anna's Archive, web-novel sites, and more) in parallel, scores results with a 0-100 confidence breakdown, and manages downloads via qBittorrent, Transmission, or SABnzbd. Wanted items get quality profiles with format ranking and cutoffs; the scheduler automatically searches and upgrades until the cutoff is met. It auto-imports into Calibre, Audiobookshelf, Kavita, or Komga, supports author monitoring with Open Library work keys, series auto-complete, Goodreads/StoryGraph CSV import, and provides Torznab and OPDS 1.2 APIs for integration with Prowlarr, Readarr, and e-reader apps. The UI is a mobile-responsive single-page app with dark theme, multi-user auth (bcrypt, TOTP 2FA, OIDC/SSO), API keys, rate limiting, Prometheus metrics, and webhook notifications (Discord, generic). It runs as a single ~17 MB static binary with pure-Go SQLite (~14 MB idle RSS), available via Docker (ghcr.io/jeremiahm37/librarr) or direct binary download for Linux, macOS, and Windows on amd64, arm64, and armv7.
