Modly

Modly is a free, open source desktop application that generates 3D models from a photo or a text prompt. All processing runs locally on the user's NVIDIA GPU, with no cloud service, account or credits, and the vendor states that nothing is uploaded, so source images stay on the machine. The app wraps open source models as installable extensions. The site names Hunyuan3D 2, TripoSG and Trellis2, and each extension is a GitHub repository that can be installed from inside the app in one click, so users can pick a balanced, fast or high fidelity model. The workflow has three steps: import an image or enter a prompt, choose a model, and generate a textured mesh that can be previewed in the app. Models can be exported as GLB, OBJ, STL or PLY for use in Blender, Unity, Unreal, other 3D software or 3D printing. Generations are organized into collections within a workspace. Modly is for indie game developers, 3D artists, makers and developers who want unlimited local generation and the freedom to swap models or change the pipeline. It is released under the MIT license, runs on Windows and Linux, and can also be run from source. The roadmap for version 0.5 includes AI powered mesh editing from plain English instructions, a smarter in app copilot and a plugin system for the editor. The app is free to download and use, and the vendor lists its price as zero.
