Why Modly

Everything you need for local AI 3D generation

Local AI 3D tools packaged into a clean, open source and lightweight desktop application

Runs on Your GPU

All inference happens locally on your NVIDIA GPU. No cloud, no queues — just your hardware doing the work.

Your Images Stay Private

Nothing is uploaded. Ever. Unlike cloud services, Modly runs entirely offline — your photos never touch a server.

High Quality 3D Meshes

Generate detailed 3D meshes ready to use in Blender, Unity, Unreal, or any 3D software of your choice.

Collections & Workspace

Organize all your generations into collections. Your workspace keeps every model accessible and easy to manage.

Multiple Export Formats

Export your models as GLB, OBJ, STL or PLY — compatible with any 3D tool or game engine right out of the box.

Open Source & Hackable

Swap the model, modify the pipeline, integrate your own tools. No black boxes — full access to every layer of the stack.

How it works

From image or prompt to mesh in three steps

01

Import an image or prompt

Drop in a photo of an object, character, or concept — or just describe it with a text prompt. A clean input gives the best results.

02

Choose a model

Pick an installed extension — balanced, fast, or high-fidelity — depending on your needs.

03

Generate the 3D mesh

Modly produces a textured mesh on your GPU. Preview it, then export to your tools.

Official extensions

A model for every need

Each extension is a GitHub repository bundling an AI model. Install them in one click from the app.

FAQ

Frequently asked questions

Yes. Modly is 100% free and open source. There are no credits, no subscriptions, and no hidden costs. Download it once and generate unlimited 3D models with no restrictions, forever.
Fully. Once installed, Modly runs entirely on your machine — no internet connection required. All inference happens locally on your GPU, so you can generate 3D models anywhere, anytime, even without Wi-Fi.
Yes. Export your model as STL and open it directly in your slicer (Cura, PrusaSlicer, Bambu Studio, etc.). Modly lets you turn any photo into a printable 3D model in minutes, for free.
Modly supports four export formats: GLB, OBJ, STL, and PLY. GLB and OBJ are ideal for Blender, Unity, or Unreal Engine. STL is the standard format for 3D printing. PLY is great for point clouds and research workflows.
Modly accepts standard image formats including PNG, JPG, and WebP. For best results, use a clear photo with the subject against a neutral background and good lighting.
Modly requires an NVIDIA GPU with CUDA support. A minimum of 6 GB of VRAM is recommended for smooth generation. AMD GPUs and integrated graphics are not currently supported.
Never. Modly has no server, no telemetry, and no upload mechanism. Your images and generated models stay entirely on your machine. This is one of the core design principles of Modly — full local privacy.
Cloud 3D services charge $20–60/month, cap your generations by credits, and upload your images to their servers. Modly is free, unlimited, fully offline, and open source. You own the full pipeline — no black boxes, no vendor lock-in.
Local AI 3D generation means running the entire AI inference pipeline on your own machine, without sending your data to any external server. Modly uses open source neural networks that run directly on your GPU to reconstruct 3D geometry from 2D photos — completely offline, for free, with no usage limits.
Unlike general-purpose local AI runners (LM Studio, Ollama), Modly is purpose-built for 3D. It packages the full local AI pipeline — background removal, neural 3D reconstruction, mesh export — into a single offline desktop app. No Python setup, no manual model download, no command line. Just install and generate.
