Octo turns Navidrome into a streaming service with a memory: search finds songs you do not own yet, they play the moment you pick them, and the ones you heart come home as properly tagged files that stay in your library forever. Point the music apps you already use at Octo's endpoint and sign in with your Navidrome login, and your library behaves as before, except search now reaches past your shelves and any result streams instantly as a preview with zero disk impact. Press plus or heart a keeper and Octo downloads the best copy it can find, FLAC first, from Soulseek peers or your own Lidarr, catches lossless files that were faked from MP3s, then identifies, tags, covers, and files the song so it appears in your library like something you bought. Bring the music you already love by importing liked songs and playlists from Spotify or any other service; Octo shows what you already own and quietly fetches the rest a few songs an hour. Stations and discovery playlists learn from your listening through Last.fm and refresh themselves, the downloads drawer shows every fetch with its full decision log, and the browser admin dashboard runs settings, notifications, family accounts, and one-click updates. 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.
