vicrodh d5f4ced66f feat(purchases): entitlement-driven formats and a DSD-safe download path
The purchases listing carries `downloadable_format_ids` per album, and
it is the only honest source for the download menu: a DSD64 purchase
streams as 16/44.1 (`hires:false`), so the catalog-derived ladder
(27/7/6/5) offered a CD FLAC the account never bought and could not
reach the DSD it did. Model the field (plus `hires_purchased`), build
the menu from it highest quality first, and keep the synthesis only as
the fallback for a listing without the field. Fixture from the first
populated capture, redacted.

The download grant is a distinct signed operation: `intent` is part of
the `getFileUrl` preimage, and a DSD entitlement answers 400 to
`intentstream` and 200 to `intentdownload` (measured live). Sign the
purchase grant with `download`, stream the body straight into the
`.part` instead of holding a 650 MB master in memory, take the file
extension from the served container (`audio/x-dsf` -> `.dsf`), verify
its magic before the rename, and leave neither `.part` nor registry row
behind on a truncated or foreign body. Tags stay FLAC/MP3-only.

The tab counters now come from `getUserPurchases?type=...&limit=1`;
`getUserPurchasesIds` counts album tracks as tracks (34 against 0 on
the smoke account). The list card and detail header badge what was
bought: 55/56 ride the hires tier with a DSD64/DSD128 detail.

QBZ

QBZ is a free and open source high-fidelity music player for Linux and macOS with fully native playback. It is a single native Rust process with a Qt/QML interface — no browser engine, no webview — with DAC passthrough, per-track sample rate switching, exclusive mode and bit-perfect audio delivery.

It plays your Qobuz subscription, your own local files, and your Plex, Jellyfin or Subsonic/Navidrome server, through the same interface and the same audio pipeline.

No API keys needed. No telemetry. No tracking. Just music.

Contents

What QBZ is and what it is not

QBZ exists as the player we wish a streaming company would give its users. It exists to fill the gap of an official client on Linux, because we don't like being second class citizens.

But it is just as important to understand what QBZ is not, and never will be. It is not a web wrapper; I did not just package the web player and "Linuxify" it. It is not a download tool, and it never will be. I built QBZ and not TDL, SPTFY or DZR because I believe music belongs to the artists, and Qobuz is, so far, the fairest option and the one with the best quality. That is why QBZ exists.

It will never have a built-in equalizer or DSP, either. The point is to send audio to your DAC untouched, bit for bit, and any processing would break that. If you want an EQ or effects, add them at the system level, for example with EasyEffects on PipeWire or a JACK graph, which make it easy.

You can download songs to listen to them offline, but they carry the same locks as the official client and the same usage window once your membership expires.

On the technical side: browsers cap audio output at 48 kHz and resample everything through WebAudio. QBZ uses a native playback pipeline with direct device control, so your DAC receives the original resolution, up to 24-bit / 192 kHz, with no forced resampling.

  • This application uses the Qobuz API but is not certified by Qobuz.
  • Qobuz is a trademark of Qobuz. QBZ is not affiliated with, endorsed by, or certified by Qobuz.
  • Offline cache is a temporary playback store for listening without an internet connection while you have a valid subscription. If your subscription becomes invalid, QBZ will remove all cached content after 3 days.
  • Local library is a "bring your own music" feature — play your own files with bit-perfect audio and the full QBZ interface, no streaming subscription required.
  • Qobuz Terms of Service: https://www.qobuz.com/us-en/legal/terms

Installation

Arch Linux (AUR)

yay -S qbz-bin    # or paru -S qbz-bin

Flatpak (Flathub)

flatpak install flathub com.blitzfc.qbz

Audiophiles: bit-perfect works in Flatpak. The sandbox needs one permission grant so QBZ can ask PipeWire to hand the DAC over cleanly (D-Bus device reservation) — without it PipeWire keeps holding the device and other apps keep mixing through it, even with exclusive mode selected:

flatpak override --user --own-name=org.freedesktop.ReserveDevice1.* com.blitzfc.qbz

QBZ shows this and the other sandbox grants under Settings → Flatpak with copyable commands, and the HiFi Wizard covers the rest. Your host audio stack still has to be configured correctly.

Snap

sudo snap install qbz-player
sudo snap connect qbz-player:alsa
sudo snap connect qbz-player:pipewire

Note: After installing, connect ALSA and PipeWire interfaces for full audio support. MPRIS media keys work out of the box.

NixOS / Nix

Add the flake input to your flake.nix:

}

Home Manager:

  ];
}

QBZ is also available in nixpkgs as qbz.

AppImage

Download from Releases: chmod +x QBZ.AppImage && ./QBZ.AppImage

macOS

QBZ is Linux-first, but macOS is a stable, fully supported platform — a proper player for Linux and Mac. PipeWire, ALSA and JACK are Linux-specific backends; macOS plays through its own CoreAudio backend, including a Core Audio Direct passthrough path for bit-perfect output. Casting (Chromecast/DLNA) and Qobuz Connect work on macOS as well.

Recommended — signed and notarized: Afonso Ramos independently maintains a Homebrew Cask, which installs without requiring a manual Gatekeeper bypass:

brew install --cask afonsojramos/qbz/qbz

You can also download the Apple Silicon or Intel DMG from the signed macOS releases. These are made from the upstream QBZ application without recompiling it; its signature metadata and DMG container are replaced, then notarized by @afonsojramos. They are not produced or endorsed by the upstream project. The mirror publishes the source commit, original checksums, and signed checksums for each release; see its trust and provenance documentation.

Official upstream alternative — ad-hoc signed, not notarized: if you prefer the artifact produced directly by the QBZ project, download the Apple Silicon or Intel DMG from QBZ Releases and drag QBZ into Applications. Because the project has no Apple Developer subscription, Gatekeeper blocks its first run. On recent macOS versions (Sequoia / 15 and later), unlock it using either route:

  • Settings route: try to open QBZ once (it gets blocked), then go to System Settings → Privacy & Security, scroll down to the message that QBZ was blocked, and click Open Anyway.

  • Terminal route (what the settings toggle does, minus the clicking):

    xattr -dr com.apple.quarantine /Applications/QBZ.app
    

    This removes the quarantine attribute macOS stamps on downloaded files — it's a one-time unlock for this copy of the app; updates installed through QBZ's own updater don't need it again.

Headless daemon (qbzd)

qbzd — headless daemon CLI and TUI

Run QBZ without a screen: qbzd is a standalone ~25 MB binary (shipped inside the deb/rpm packages and as its own tarball) that turns any Linux box — a Raspberry Pi, a NAS, the living-room mini-PC — into a bit-perfect Qobuz Connect endpoint that appears in the official Qobuz apps like a hardware streamer. It needs only glibc 2.35+ on x86_64 and arm64 (Raspberry Pi OS bookworm and trixie, 1 GB boards included) — deliberately lower than the arm64 desktop app's 2.39, so a trimmed Pi image stays a valid target.

  • Daemon + full CLI + terminal setup wizard (TUI) in one binary
  • Browser-based login that works over SSH; one-file settings hand-off from desktop QBZ
  • HiFi wizard with copyable audio-stack config blocks (clipboard works over SSH)
  • MPRIS out of the box, live JSON events (qbzd watch), service files for systemd/OpenRC/runit
  • Event hooks: qbzd settings set hooks.script /path/to/script runs your script on playback/session events with QBZ_* environment variables — push integration for audio-box distros (moOde, Volumio, DIY setups), no polling required

Kiosk mode

For Raspberry screens and handheld consoles.

QBZ Kiosk Mode on a handheld console

A touch-first face for touchscreens and small panels: set QBZ_PROFILE=kiosk and QBZ boots a big-target shell with its own NavRail, touch scrolling, an on-screen keyboard, and a centerpiece Now Playing with cover↔lyrics toggle and queue/history tabs. Switch between Kiosk and Desktop live from the Now Playing layout menu; fullscreen is opt-in via QBZ_KIOSK_FULLSCREEN=1.

Tech stack

QBZ is a single native Rust process. The UI is Qt/QML, bound to the Rust core through cxx-qt: the QML scene graph and the Rust backend live in the same process and talk through generated QObject bridges — there is no browser engine, no webview and no IPC boundary to serialize across.

Layer Technology
Desktop shell + UI Qt 6 / QML via cxx-qt (native, single process — no webview, no IPC)
Custom rendering Qt RHI scene-graph items + baked .qsb shaders (visualizers, immersive scenes, waveform)
Audio decoding Symphonia (all codecs) via rodio
Audio backends Linux: PipeWire, ALSA (alsa-rs, incl. Direct hw:), PulseAudio, JACK. macOS: CoreAudio (incl. Core Audio Direct)
Networking reqwest (rustls-tls)
Database rusqlite (bundled SQLite, WAL mode)
Desktop mpris-server (Linux MPRIS), souvlaki (macOS media controls), ksni (Linux tray), keyring
Casting rust_cast (Chromecast), rupnp (DLNA/UPnP), mdns-sd
i18n qbz-i18n, gettext-style .po bundles compiled into the binary (8 locales)

Multi-crate architecture

The Rust workspace lives entirely under crates/ (manifest crates/Cargo.toml). qbz-qt is the application crate — it owns the QML tree, the cxx-qt bridges and the RHI items, and produces the qbz binary. Everything below it is frontend-agnostic. A representative slice of the workspace:

  qbz-qt/                Application crate: QML tree, cxx-qt bridges, RHI items
  qbz-app/               Application-level orchestration (non-UI)

Building from source

QBZ is a pure Rust workspace — there is no Node.js, no npm install, no webview. The workspace manifest is crates/Cargo.toml and the application crate is qbz-qt, which builds a binary called qbz.

Prerequisites

  • Rust stable. No nightly, no mold, no custom RUSTFLAGS — the build needs none of them, and setting any of them invalidates the whole build cache for no gain.
  • Qt 6.8 or newer, including its development headers and the private headers (<rhi/qrhi.h> lives in Qt's private tree and the custom scene-graph items need it).
  • Linux or macOS with audio support.
  • No Node.js/npm required.

System dependencies

Debian / Ubuntu:

sudo apt install build-essential pkg-config cmake clang libclang-dev nasm \
  qt6-base-dev qt6-base-private-dev \
  qt6-declarative-dev qt6-declarative-private-dev \
  qt6-shadertools-dev \
  libasound2-dev libjack-jackd2-dev libdbus-1-dev libssl-dev

qt6-shadertools-dev provides qsb, the shader baker. It is optional: the .qsb files are committed, so a build without qsb simply keeps them (the build prints a warning). You need it if you intend to modify a shader.

Fedora, Arch, Gentoo and other distros: package names differ; look for the equivalents of the list above — a C/C++ compiler plus clang/libclang, cmake, nasm, the Qt 6 Base and Declarative modules with their development and private headers, Qt Shader Tools, and ALSA, JACK, D-Bus and OpenSSL development headers. Please open a PR if you confirm exact package names for your distro.

macOS: Xcode Command Line Tools (xcode-select --install), a Rust toolchain, and Qt 6 — Homebrew's qt is what the build is tested against (brew install qt); the build script finds it at /opt/homebrew/opt/qt without any PATH fiddling.

Build and run

git clone https://github.com/vicrodh/qbz.git && cd qbz
cargo build --release --manifest-path crates/Cargo.toml -p qbz-qt
./crates/target/release/qbz

A release build from scratch is on the order of ten minutes on a modern desktop; incremental builds are a couple of minutes. The UI is QML and is loaded at runtime, so a change that touches only .qml does not go through rustc at all.

The build script: scripts/qt-run.sh

The repo ships the build script we use ourselves. It runs the static QML audits first (they catch the class of mistake cargo check cannot see — a missing component, or a call to a bridge member that does not exist — in about a second), then builds and executes the binary directly:

./scripts/qt-run.sh             # build (release) and run
DEBUG=1    ./scripts/qt-run.sh  # debug profile
NORUN=1    ./scripts/qt-run.sh  # build only
TEST=1     ./scripts/qt-run.sh  # also run the crate's tests
SMOKE=1    ./scripts/qt-run.sh  # offscreen smoke run instead of the GUI
NO_AUDIT=1 ./scripts/qt-run.sh  # skip the QML audits
JOBS=4     ./scripts/qt-run.sh  # cargo build jobs

It works on Linux and macOS.

Nix / NixOS

flake.nix builds the same binary via rustPlatform.buildRustPackage with the crate root at crates/ — see the NixOS / Nix install section above, or run nix build / nix develop directly from a checkout.

API proxy

Last.fm, Discogs, Tidal, Spotify-import and MusicBrainz traffic goes through a hosted Cloudflare Workers proxy (qbz-api-proxy.blitzkriegfc.workers.dev) that holds all credentials server-side. Both pre-built releases and source builds use it out of the box — no API keys or .env file required.

If you want to run against your own proxy (for development, or if you fork QBZ), the proxy source lives at vicrodh/qbz-api-proxy. Deploy it with wrangler deploy and then edit the *_PROXY_URL constants in crates/qbz-integrations/src/lastfm/client.rs, crates/qbz-integrations/src/discogs/mod.rs, crates/qbz-playlist-import/src/providers/tidal.rs and crates/qbz-integrations/src/musicbrainz/client.rs to point at your worker before rebuilding.

Environment variables

QBZ picks a working renderer at startup and reverts automatically if a forced choice fails to produce frames, so there is normally nothing to configure. The renderer can also be set from Settings → Appearance; the environment variable overrides it for one launch.

Variable Effect
QBZ_RENDERER=auto (or gpu, hardware, hw) Qt's default backend — the GPU path. This is the default
QBZ_RENDERER=gl Force the OpenGL backend (QSG_RHI_BACKEND=opengl) on Linux. On macOS this resolves to Metal
QBZ_RENDERER=software (or cpu, soft) Force the software renderer (QT_QUICK_BACKEND=software) — for VMs and broken GPU stacks
QBZ_PROFILE=kiosk Boot the touch-first Kiosk shell (desktop for the normal one)
QBZ_KIOSK_FULLSCREEN=1 Start Kiosk mode fullscreen

Qt's own variables (QSG_RHI_BACKEND, QT_QUICK_BACKEND, QT_QPA_PLATFORM, QT_SCALE_FACTOR…) work as usual and take precedence over QBZ_RENDERER.

If QBZ fails to start, try QBZ_RENDERER=software qbz first.

Known issues

  • Hi-Res seeking — seeking in tracks above 96 kHz can take 10–20 s (the decoder must scan from the start). Use prev/next for instant navigation.
  • ALSA Direct — exclusive access blocks other apps. Use your DAC's or amplifier's physical volume control.
  • DSD DoP / native mode — seeking is disabled and volume is fixed while a DoP or native-DSD stream is active (any sample manipulation would corrupt the DSD stream). Convert-to-PCM mode has no such limits.
  • Multichannel DSD comes out as stereo — DoP and native passthrough are two-channel by design (a DoP receiver is a stereo device). Multichannel sources therefore play through the convert-to-PCM path, which folds up to 5.1 down to stereo (ITU-R BS.775, LFE dropped); 7.1 and above are not supported and the file will not load. SACD discs play their stereo area.

Reporting a problem

Having trouble with the app? Please report it in the issue tracker.

What makes a problem solvable: a title that names the actual symptom, the logs, and a screenshot when it is something you can see. QBZ ships a tool for the logs so you don't have to go hunting for files — Settings → Share logs, pinned at the bottom of the Settings sidebar, opens the in-app log viewer. From there you can filter by level, search, copy the log with secrets redacted, or upload it and get a link to paste into the issue.

On LLMs and AI tools

This project started about two years ago. I wrote the first version in Python, which is my main stack. Then it became my Rust learning project — most of the logic was written by hand, as a hobby, a proof to myself of what I could build and how much I could learn. It then sat frozen for a long time.

Then LLMs went mainstream. They helped me put a real UX on top of what I already had, they unblocked problems I had never found the time for, and they compressed work that, at the pace and the hours I could actually give it, would have taken months — or would have left the project sitting in a folder on my NAS forever.

Somewhere along the way QBZ filled a gap, and that made it relevant. Paying attention and caring about the details also means more responsibility, and more responsibility means more transparency: the project started by hand, but the amount of code I type myself today is minimal. That does not mean the code is careless. It goes through the same standards I use in my day job — the real one — it is under continuous improvement, and it is always open to comments, suggestions, requests and issue reports.

Using AI tools does not mean I ask an LLM for every feature or change that crosses my mind, and it does not mean every request for a change or a new feature gets accepted without analysis. I go out of my way to avoid that rabbit hole — have a look at the issues. So if you come up with something new, help me by explaining it and justifying it. If I don't understand it, it is very unlikely to go in, because I cannot measure it or test it properly.

I know we all want a lot of things. But keeping this app from turning into The Homer is real work.

If you have a problem using software built with AI tools, this software is probably not for you.
