Modly

Modly is an open-source desktop app that generates 3D meshes from 2D images. The application runs entirely on the local GPU, removing the need for cloud based processing and external API dependencies. It is available as a desktop application for Windows, Linux, and Apple Silicon macOS.

Users can install the software via provided installers or run it directly from the source repository using a launcher script. The application manages a Python backend for AI processing and a frontend for mesh visualization and workflow management. It targets users who need to convert photos into 3D assets while maintaining full control over their hardware and data.

Key features

• Local image to 3D mesh generation using GPU acceleration
• Extension system for installing new models via GitHub repositories
• Support for multiple models including Hunyuan3D 2 and TripoSG
• In-app tools for smoothing and decimating imported meshes
• Live RAM indicator displayed in the top bar
• CLI for automating generation and checking system health
• Workflow validation to prevent mesh view loss during errors
• Export functionality for generated 3D assets

The software utilizes a modular architecture that allows for the addition of external model and process extensions. These extensions are defined by a manifest file and runtime entry files, enabling the integration of various AI models like Trellis2 GGUF. For automation, a dedicated CLI allows scripts and agents to trigger generation tasks, list available models, and poll status via JSON output without interacting with the graphical user interface. The system also includes experimental orchestration helpers for ComfyUI workflows, treating the final 3D asset as the primary artifact for download.

Modly is designed for designers and developers who require local control over AI 3D generation and the ability to extend model capabilities through a self hosted environment.
