Modly is an open-source desktop application developed by Lightning Pixel designed for local, AI-powered image-to-3D mesh generation. Available for Windows, Linux, and Apple Silicon macOS, the software utilizes the user's local GPU to transform 2D photos into 3D models. The application features a node-based workflow system where users can construct pipelines, such as an "Image -> Generate Mesh -> Add to Scene" sequence. Technical capabilities include in-app mesh smoothing and decimation, with optimized results saved directly back to the workspace. Modly supports a modular architecture through external model and process extensions, which are installed via GitHub repository URLs containing a manifest.json file. For automation, the project provides a Python-based CLI (stdlib-only) that allows agents and scripts to interact with the running application via canonical commands like health, model, and workflow-run. The CLI facilitates complex operations, such as the "generate" command, which invokes the POST /workflow-runs/from-image endpoint, polls the job status, and exports the resulting .glb file. While the core focuses on local execution, the tool also provides experimental orchestration helpers for ComfyUI workflows to facilitate external 3D asset generation.
