Desktop app
The same nine design modules as the browser, as a native install for Windows, macOS, and Linux. After you activate a Premium license, it runs offline, uses native file dialogs, and stores the license locally. Installers ship from your Gumroad receipt.
Same workbench. Native files.
Desktop is not a different product. Every module, Print preset, and export format matches the web app. The difference is how files and the license live on your machine.
- Native Save / Open — File > Open and Save As use the operating-system dialog. You pick where
.3dsynthprojects, G-code, and STL/OBJ/glTF land. - Offline — after install and license activation, code, assets, and docs ship inside the app bundle. No network round-trip to stay activated.
- Presets on disk — machine, material, and nozzle JSON lives in the OS app-data folder, not only in browser storage.
- Recent files — the File menu remembers recently opened projects.
- No analytics — Plausible and Clarity load only in the web build.
Platforms
Windows
Windows 10 or newer, 64-bit. Installer (.exe) sets up the app and a shortcut.
macOS
macOS 11 Big Sur or newer. Apple Silicon and Intel. Drag the .app from the .dmg into Applications.
Linux
64-bit .tar.gz archive for most distributions. Extract and run the included binary, or integrate it with your launcher. (This matches the current desktop build; it is not an AppImage.)
The Free web tier stays in the browser. Desktop requires Premium — see Free vs Premium.
Install from your receipt.
