Local sample library manager for producers. Splice-inspired interface, fully offline. Browse, filter by BPM/key, preview audio and MIDI, and organize your own library.

- Download the
.dmgfrom the releases page or stack.swendl.com - Open the DMG and drag Stack.app to your Applications folder
- If macOS says "Stack is damaged and can't be opened", run this once in Terminal:
xattr -rd com.apple.quarantine /Applications/Stack.app- Launch Stack from Applications
This warning appears because the app is not yet notarized with Apple. The command removes the quarantine flag macOS applies to downloaded files.

- Folder-based browser with pack organization
- Browse your library from a phone or another computer on the same network
- Auto-update flow via GitHub Releases
- Desktop: Tauri 2.0

~/.local/share/app.stack.desktop/stack.db - Windows:
%APPDATA%\\app.stack.desktop\\stack.db

Stack runs a small HTTP server while the desktop app is open, serving the same UI from the same database. Open it in Chrome or Safari on this machine, or on your phone, and you are looking at the same library — nothing is uploaded anywhere.
Set it up in Settings › Web access:
- Serve Stack in a browser — on by default. Binds
127.0.0.1only. - Allow other devices on this network — off by default. Binds
0.0.0.0so phones, tablets and other machines on the same Wi-Fi can reach it. - Copy the URL shown for Other devices and open it on the phone.
Both toggles and the port take effect immediately; the app does not need a restart.
A random token is generated on first run and kept in the app data directory, so
the URL stays valid across launches. The URLs shown in Settings already include
it as ?token=….
- While Stack is bound to loopback only, local requests need no token.
- The moment Allow other devices is on, every request to
/__ipc,/__mediaand/__eventsmust present the token — as?token=, anAuthorization: Bearer …header, or thestack_tokencookie the server sets the first time a page is opened with a valid token. Anything else gets a 401.
The token is the only thing standing between your network and your library, and the bridge exposes the full command set (including folder removal and plugin deletion). Treat the link like a password, use it on networks you trust, and leave LAN access off when you don't need it.
No, and there is no Stack Docker image. Stack is a desktop application: the Rust backend and the native webview are one process, and the webview needs a display server. There is nothing to run headless in a container.
What the network access above gives you is the same practical result for most people — run the desktop app on the machine that holds your samples, turn on Allow other devices, and use any browser on your network as the client.
- Launch the app.
- Click Add Folder in the sidebar.
- Select a folder containing samples, MIDI, or presets.
- Wait for indexing to complete.
- Search, filter, and preview assets in the Browser tab.
