Description

Spotify on Windows has always been a website in a box. Wavee speaks Spotify’s protocols itself and draws its own interface, so it opens in under a second and holds full refresh rate through a 10,000-song library.

New in 0.3 “Crest”: a rebuilt Home, a real full-screen view with eight visualizers driven by the audio you hear, lossless FLAC, pages for podcast episodes and people, and playback that no longer stutters when your PC is busy.

Spotify Connect in both directions
Lyrics synced to the syllable, beside the player or full screen
Tempo, key and listening stats across your library
YouTube, Twitch and radio as out-of-process modules

FluentGpu

A from-scratch UI engine for .NET 10. You write UI in plain C#; state lives in signals, so a change re-runs only the component that read it. It paints with Direct3D 12 and DirectWrite and ships as one NativeAOT binary.

    return VStack(12,
      Heading($"Count: {count}"),
      Button.Accent("+", () => setCount(count + 1)));
  }
}
// a click re-renders Counter, nothing else
