# Alternatives to Calibre-Web Web UI over your Calibre library. Calibre-Web ranks #5 of 11 in Media servers, with an Alt Score of 46. It is licensed under GPL-3.0, free and available on Windows, macOS and Linux. 10 of 10 checklist rows are verified against a public source. Source: https://altcatalog.com/alternatives/calibre-web/ Category: Media servers ## Overview - **Who it's for**: People who already maintain a Calibre ebook library and want to browse, read, and manage it from a browser or e-reader instead of the desktop app — useful for households or small groups sharing one collection. - **What you get**: A responsive web UI over an existing Calibre database (metadata.db) with in-browser reading for multiple formats, search/filtering, custom shelves, and metadata editing. It supports multi-user accounts with granular permissions and various auth methods (OAuth, LDAP, proxy). OPDS feeds and Kobo sync let e-readers and reading apps pull books directly, and optional Calibre binaries enable on-the-fly format conversion. - **How it works**: Point Calibre-Web at an existing Calibre library folder, run it as a self-hosted service (e.g., via Docker), and users log in through a browser to browse, read, download, or sync books; it does not create or manage the Calibre library itself, only serves it. ## Profile - **License**: GPL-3.0 (verified 2026-07-11) - **Pricing model**: Free (verified 2026-07-11) - **Starts at**: ? - **Platforms**: Windows, macOS, Linux - **Status**: active (verified 2026-07-11) ## Ranked alternatives | # | App | Alt Score | Licence | Platforms | |---|-----|-----------|---------|-----------| | 1 | [Emby](https://altcatalog.com/alternatives/emby.md) | 96 | Proprietary | Windows, macOS, Linux | | 2 | [Jellyfin](https://altcatalog.com/alternatives/jellyfin.md) | 91 | GPL-2.0 | Windows, macOS, Linux | | 3 | [Kodi](https://altcatalog.com/alternatives/kodi.md) | 78 | GPL-2.0 | Windows, macOS, Linux | | 4 | [Navidrome](https://altcatalog.com/alternatives/navidrome.md) | 60 | GPL-3.0 | Windows, macOS, Linux | | 5 | [Audiobookshelf](https://altcatalog.com/alternatives/audiobookshelf.md) | 46 | GPL-3.0 | Windows, macOS, Linux | | 6 | [Komga](https://altcatalog.com/alternatives/komga.md) | 46 | MIT | Windows, macOS, Linux | | 7 | [Kavita](https://altcatalog.com/alternatives/kavita.md) | 42 | GPL-3.0 | Windows, macOS, Linux | | 8 | [Plex](https://altcatalog.com/alternatives/plex.md) | building | Proprietary | ? | | 9 | [Stremio](https://altcatalog.com/alternatives/stremio.md) | building | ? | ? | | 10 | [Universal Media Server](https://altcatalog.com/alternatives/universal-media-server.md) | building | ? | ? | Alt Score = Verified coverage (90%) + Visibility (10%).
