Modly is a desktop application that generates 3D models from images using local AI models running entirely on your GPU.

The tool solves the problem of converting photographs into 3D meshes without relying on cloud services or external APIs. It runs open source AI models locally on your machine, keeping all processing offline and private. The application uses a node-based workflow system where users connect steps like image input, mesh generation, and scene composition to define their conversion pipeline. Workflows are validated before execution, with invalid graphs surfacing warnings rather than failing silently, and users can further refine results by smoothing and decimating imported meshes within the application.

Modly suits developers and creators who want image-to-3D conversion without cloud dependencies and have GPU hardware available. It works on Windows, Linux, and Apple Silicon macOS. The tool's extension system allows adding new AI models and processing steps through external GitHub repositories, with several official extensions available including variants of Hunyuan3D and TripoSG models. Extensions can be installed directly from the application by providing a repository URL, and models can be downloaded on demand.

The project maintains an active extension ecosystem with multiple official model implementations available. Development includes platform-specific optimizations such as native window controls on macOS and a live RAM indicator in the application interface. The codebase is written in TypeScript with a Python backend, and the project provides both packaged installers and the ability to run directly from a cloned repository in development mode.
