Open SourceBuilt in the open,
because music should be free.
Grovy started as a weekend project — a frustration with bloated music players that track everything you listen to. No ads, no accounts, no telemetry. Just a clean player that respects your time and your data. The entire source code is on GitHub under the MIT license.
What it does
Streams from multiple sources
Grovy pulls from JioSaavn and YouTube Music simultaneously, interleaves results, and lets you play anything instantly. No account needed.
Ambient UI that adapts to your music
Album art colors are extracted in real-time using ColorThief. The entire interface — backgrounds, gradients, accents — shifts to match whatever you're listening to.
Proper audio handling
HLS adaptive streaming for JioSaavn tracks, YouTube IFrame API for YT content, with automatic codec selection preferring opus/webm at the highest available bitrate.
Runs entirely in the browser
Playlists, favorites, play history, volume — everything is stored in localStorage. There is no backend database. Your data never leaves your device.
