Release Sonar

Welcome to Release Sonar

Hi, I am Echo

Release Sonar tells you when the artists in your music collection put out something new. No account, no sign-up: everything stays in your browser.

Import your library

Choose how to tell Release Sonar what you listen to. Only names are read; nothing leaves your device except artist names sent to MusicBrainz to find them.

Your browser may say it will "upload" the files. It won't: we only read the names, and you can check it in the network panel.
