You bought the records. You ripped the FLACs. SugarSpin plays your lossless library from any device in the house, runs on any NAS, Mac, or PC, and asks you to pay exactly once. Yours forever.
A dark, immersive interface that puts streaming services to shame. Browse your albums, discover your artists, watch your music move. Every screen below is a real screenshot from the app, not a marketing render.
Every feature was built because we actually use them. Lossless playback, smart categories, auto album art, optional Tube Warmth, ReplayGain volume normalization. All running on your hardware, not someone else's cloud.
FLAC, ALAC, AIFF, WAV, OGG, OPUS, AAC, M4A, MP3. Your files stream from your server to your browser or speaker untouched. No transcoding, no down-sampling, no re-encoding. 16-bit, 24-bit, even 24-bit / 192 kHz hi-res masters arrive at the player exactly as you ripped them.
Embedded artwork extracted automatically. Missing covers? Hit one button and SugarSpin fetches them from MusicBrainz instantly.
Fully responsive web app. Use it on your desktop, tablet, or phone. Add it to your home screen for an app-like experience. No app store needed.
No cloud. No telemetry. No analytics. Your music never leaves your computer. Everything runs on your own hardware, in your own home.
Auto-organized by genre with beautiful colored tiles. Rock, Jazz, Hip-Hop, Classical, Soundtrack... browse your collection the way it was meant to be.
Create custom playlists, mark favorites, and build your perfect listening experience. Everything persists across sessions and updates.
Fix incorrect album names, artists, genres, and years with one click. SugarSpin looks up your entire library on MusicBrainz and corrects the metadata automatically.
Control playback from your phone while audio plays on your desktop. All devices stay in sync in real time. Choose which device outputs the sound.
Stream your library straight to your dashboard. Compatible with the Subsonic API, so any app like Amperfy on iOS or Ultrasonic on Android lets you browse and play your collection from the steering wheel. Pro & Gold only.
SugarSpin natively controls Bluesound speakers and NAD amps (the whole BluOS ecosystem). Pick your Node, Powernode, Pulse, M10, or M33 from the device picker and stream straight to the hi-fi gear in your living room. Track title, artist, and cover art show on the speaker's own display. Pro & Gold only.
VU meters, spectrum analyzer, oscilloscope, and wave forms now animate from the actual audio while casting to your Bluesound or NAD speaker. SugarSpin decodes the track server-side at 30 frames per second and pushes the levels to every connected browser in sync. Pro & Gold only.
Karaoke-style scrolling, full-screen Spotlight, or gentle Wave animation. Lyrics fetched from LRCLib with an automatic NetEase Cloud Music fallback for huge coverage gains on older, Asian, and indie tracks. Three animation styles. Cached forever once found.
A fresh 25-track playlist every day, mixed from your favorite artists, albums you haven't played in a while, and deep-cut surprises. Auto-refreshes; press Shuffle for an on-demand re-pick. Algorithmic but human-feeling.
Quiet tracks and loud tracks sit at consistent levels. Reads industry-standard track and album ReplayGain tags from your files. Three modes in Settings: Off, Track, or Album. No more reaching for the volume between songs.
A built-in vacuum-tube saturation stage that adds gentle even-order harmonics and soft compression to every track — the warmth of a real tube preamp, in the browser. Four presets (Off, Subtle, Warm, Vintage) plus a custom Drive slider. Your source files are never modified.
A new Now Playing view: four photoreal vacuum tubes glowing amber over a warm bokeh field, breathing gently with the song’s loudness on a slow 5-second cycle. A red filament glow at the base of each tube simulates the heat. Looks great on iPad, iPhone, and desktop in any orientation.
I collect vinyl, cassettes, MiniDiscs, and reel-to-reel tape. I built SugarSpin because no music player treated my digital library with the same love I give my physical collection. The spinning record, the tonearm, the VU meters... it all exists because I wanted to feel something when I pressed play.
Real collectors. Real libraries. Real reactions.
"I have 4TB of FLAC on my Synology and nothing played it beautifully until SugarSpin. The vinyl view alone is worth the price. My wife actually uses it now too."
"Cancelled my big-name lossless subscription after three years. All my music was already on my hard drive, and SugarSpin made it feel like the slick streaming app I used to pay for. Install took two minutes."
"The vinyl view with the spinning record and tonearm is gorgeous. I put it on my TV while listening and it feels like having a turntable without the maintenance. Beautiful work."
"I tried a few of the popular self-hosted players first. They're fine for video, but none of them treated music with this kind of care. The album art, the categories, the obvious attention to detail, this was clearly built by somebody who actually listens."
"$49 once. No subscription. Just my music, on my server, looking gorgeous. I literally showed it to everyone at our record swap last weekend. Three people bought it on the spot."
"Set it up on my Synology, added it to my phone's home screen, and haven't opened the big streaming app since. The VU meters are pure ear candy. It feels like owning a hi-fi rig."

Lossless FLAC to everyday MP3, SugarSpin handles them all. Got duplicates? It automatically picks the highest-quality version so you don't have to.
Streaming services raise prices on their own schedule. A certain popular media app recently bumped its lifetime to around $700. SugarSpin is a one-time purchase that works forever, even offline. No subscriptions, no premium tier, no annual price-creep email, no tricks.
The $89 Gold price is available at the time of your initial purchase only. If you buy Pro now and decide to upgrade later, Gold returns to its regular $129. We'll still take care of Pro upgraders with a loyalty discount, but the best deal on Gold is right here, right now. All prices in USD — one-time, lifetime license, no subscriptions, no renewals, ever.
SugarSpin is here. Take your music back. Install free in 2 minutes, or grab a Pro or Gold license to unlock your full library.
