Free, with no adverts and nothing to sign up for. Your music is only ever read, never changed; everything Stellody learns about it stays on your computer.
Latest releaseWindows 10 or 11, 64-bit
Download for WindowsRun the file and follow the screens. It installs just for you, so Windows asks for no administrator password. It can add a desktop shortcut, a Start menu entry and Stellody waiting by the clock when you sign in. Run it again later to update, repair or remove it.
macOS 13 or later, Apple silicon
Download for macOSOpen the disk image and drag Stellody to Applications. The first time you point it at music in Documents, on the Desktop or on an external drive, macOS asks you to allow it; your Music folder needs no permission.
Any distribution with Flatpak, 64-bit
Download for LinuxInstall it with flatpak install --user stellody.flatpak, then run it
from your applications menu. It can read your home folder and removable drives but write to none
of them: Stellody never writes to a music file, so it is not given the means to.
Press the folder button at the top left and point Stellody at your music. It remembers, so you do this once.
Choose File then Discover new music, tick the genres worth looking in and let it run: it returns albums by your artists that you do not hold, plus artists close to them. It takes minutes, because the public catalogues ask to be questioned slowly.
FLAC, MP3, Ogg, Opus, WAV, AIFF, M4A, WMA, WavPack and AAC are read; Monkey's Audio, Musepack, DSD, TAK, TrueAudio, CAF and M4B audiobooks are not. WMA, WavPack and AAC were proved against files the test suite encodes, so if one of yours reads wrongly please report it.
Anything Stellody cannot decode is named in its health report, so an album it cannot play says so instead of vanishing.
Bought a new album? Press Rescan; Stellody reads only what changed.
Once you have rated and corrected a few albums, choose File then Back up library. One zip keeps your ratings, play counts, corrections and settings; Restore from backup puts them back, even on another computer.
Stellody says when a newer version is out and nothing otherwise. The check sends nothing about you or your music, not even your version: it names the program and asks for one public page.
