The music player that wears a skin

Nastro is a lightweight, native music player. Player, equalizer and playlist dock together, and the look is a skin you can swap. No account, no cloud, no telemetry: it plays your local files.

Nastro in the Silver skin: the player playing a track with its spectrum visualizer, the equalizer below it and the playlist at the right.

Nastro in the Graphite skin: the player playing a track with its amber spectrum visualizer, the equalizer below it and the playlist at the right.

Native, not a browserWritten in Rust on gpui, the GPU accelerated UI framework behind the Zed editor.
Light on your machineNo bundled web engine. An idle player does no work, so it stays small and quiet.
Local firstNo sign in, no sync, no telemetry. It plays the files on your disk.
Yours to keepOpen source under Apache-2.0, with a documented skin format.

Features

A classic layout, built to be changed

Three panels, one small program.

Docked panels

The player, a 10-band equalizer and the playlist snap to each other with magnetic edges and move as one group, or come apart to dock somewhere else.

Skins

Four built-in skins (Silver, Graphite, Porcelain and Nebula) and your own in a plain skin.toml file. Support for classic skins is planned.

Its own audio pipeline

FLAC, MP3, Opus, Ogg Vorbis, WAV, AIFF, AAC and ALAC, with a real equalizer, a spectrum visualizer and gapless playback.

Playlists as text

Playlists are plain M3U files, so other tools can read them and nothing locks you in.
