When the internet goes away, your library does not have to: Zimi serves Kiwix ZIM archives of Wikipedia, books, videos and forums through a rich web interface, with one search box querying every archive across more than 100 million articles. Each content type gets its own app: Zimipedia for wikis, the Dictionary for Wiktionary, Bookshelf for books, ZimiTube for video, ZimiExchange for Q&A, Reddot for subreddits and offline street Maps. Bookmarks, lists, likes and highlights live in every app and sync across devices when you sign in, and any article can switch into whichever language edition you hold. The library manages itself: browse the Kiwix catalog of over 1,000 archives, download with one click, let auto-updates keep editions fresh, and seed downloads over BitTorrent with a ratio cap you set. Zimi servers on the same network find each other and pass archives at LAN speed, and one offline switch turns off every internet-bound feature for air-gapped rooms. You can also make your own ZIMs from a web page, a whole site, a video playlist or a folder of files. Access ranges from public to sign-in only with per-archive allowlists, and the JSON API plus MCP server let AI agents search the same library. Docker runs Zimi on port 8899 with your ZIM files and config mounted as volumes. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. GPL-3.0 licensed.
