A lightning-fast, offline-first 3D asset manager and companion with native drag-and-drop support for your creative workflow.
DragNProp is a professional desktop utility designed for 3D game developers, digital artists, and creators. It operates as a local "stash" manager, bridging the gap between your offline asset libraries and production applications (such as Blender, Unity, Unreal Engine, Godot, Maya, and 3ds Max) through a seamless, premium drag-and-drop workflow.
Built on the modern Tauri v2 and Svelte 5 stack, DragNProp is ultra-lightweight, offline-first, and backed by a local SQLite engine to guarantee blistering speed and absolute data privacy.
Organize your complex model directories with a nested, hierarchical category system. The UI stays sleek, responsive, and adapts perfectly to large asset lists using virtualization.
Inspect your items, edit asset properties, manage technical documentation/sheets, view texture folders, and review 3D model properties directly inside the companion application.
- ⚡ Offline-First & Blazing Fast: No cloud accounts, no subscription, and no telemetry. All metadata, index tables, and thumbnails are stored entirely on your local machine using SQLite.
- 📦 True Drag-and-Drop Workflow:
- External OS Dragging: Select any 3D asset and drag it directly out of the DragNProp window into external apps (Blender, Unity, Unreal, Windows Explorer, etc.). The native OS-level file drop is handled via a customized Rust backend.
- Internal Organization: Move assets between categories or nest/reorder folders with a fluid mouse-pointer drag interface.
- Quick Import: Drag files or folders from Windows Explorer directly onto categories or specific asset cards to initiate imports instantly.
- 🤖 Automatic 3D Preview Engine:
- Recursively monitors and scans your selected stash directory.
- Supports popular 3D models (
.glb,.gltf,.obj,.fbx,.stl) and images (.webp,.png,.jpg,.jpeg). - Leverages a fast background pipeline powered by
@google/model-viewerand Svelte to auto-render and capture high-resolution thumbnail previews.
- 🔍 Recursive Scoped Search: Instantly filter models globally or lock search queries to a specific parent category and all its nested subcategories.
- ♻️ Physical Recycle Bin System: Never worry about accidental data loss. Deleting assets moves them to a hidden
.trashdirectory on your drive, allowing full recovery or safe bulk emptying at any time. - 📌 Always on Top Utility Mode: Toggle the pin button to lock the DragNProp window on top of other applications, enabling a convenient sidebar workflow when composing scenes in your 3D engines.
DragNProp expects and maintains a clean, modular folder layout in your library. When a directory is marked as an Asset, it scans and organizes the files under the following structure:
📁 My_Stash_Library/
│
├── 📁 Uncategorized/ # Automatically created for orphan assets
│
└── 📁 Weapons/ # Category Folder
│
├── 📁 SciFi_Blaster/ # Asset Folder (Identified by 3D model presence)
│ ├── 📄 .dragnprop_id # Hidden unique UUID file (keeps DB references intact)
│ ├── 📄 blaster_model.glb # Primary 3D object file (.glb, .gltf, .obj, .fbx, .stl)
│ │
│ ├── 📁 sheets/ # Auxiliary diagrams, blueprints, and orthographic references
│ │ └── 📄 blueprint.png
│ │
│ ├── 📁 textures/ # Model textures and materials
│ │ ├── 📄 base_color.png
│ │ └── 📄 normal.png
│ │
│ └── 📁 preview_images/ # Cached thumbnails generated automatically by DragNProp
│ ├── 📄 manual_preview.webp
│ └── 📄 blaster_model.glb.thumb.webp
│
└── 📁 Melee/ # Subcategory Folder
