Skip it if

Skip Modly if you don't have an NVIDIA GPU with at least 6GB VRAM, or if you need a turnkey cloud solution with collaborative features and production-ready assets out of the box.

The 30-second take
Biggest gripe

You'll need a powerful NVIDIA GPU (6GB VRAM minimum) to run Modly smoothly, which is a hardware cost not included in the free software.

Price reality

Modly is completely free and open source, which makes it the cheapest option among AI 3D generation tools. Cloud competitors like Meshy or CSM charge $20–60 per month with credit limits. While Modly requires a capable GPU, the software itself costs nothing, and for users already owning such hardware, it offers unlimited generation with no recurring fees.

About Modly

FreeIntermediateNo APIDesktop · CLI

Modly is a free, open-source desktop application that turns a single photo or text prompt into a textured 3D mesh entirely on your local NVIDIA GPU. It works fully offline—no account, no credits, and no data uploads. You can export your models in GLB, OBJ, STL, and PLY formats for use in game engines, 3D printing, or modeling software. The app is powered by open-source AI models like Hunyuan3D 2, TripoSG, and Trellis2, which you can install via a one-click extension system. The latest v0.4.1 release adds While Loop nodes, a workflow browser, and native macOS support, making it a serious contender for structured, repeatable generation tasks. Modly suits indie game developers, 3D printing enthusiasts, and privacy-conscious creators who want full control over their 3D asset pipeline. The node-based workflow editor lets you chain operations like remeshing or looping, and the Modly Agent plus CLI enable automation for batch tasks. A Gaussian Splat viewer and workspace asset library help you organize and review your generations. Everything happens locally—your images never leave your machine. This contrasts with cloud services like Meshy or CSM, which upload data and charge per render. Modly is free and offers unlimited generation, but it does require a powerful NVIDIA GPU with at least 6 GB of VRAM (Apple Silicon is supported from v0.4.0, but with limitations). For developers, the open-source pipeline is fully hackable—you can swap models, modify the pipeline, or integrate your own tools. Extensions are GitHub repositories you install in one click, and the community is active on Discord and GitHub. If you value privacy and zero cost over cloud convenience, Modly is the standout local option.

Behind the Verdict

Modly stands out in the AI 3D generation space for its uncompromising commitment to local, private, and free generation. Unlike cloud services that charge subscription fees and upload your data, Modly runs everything on your own hardware. This is a major advantage for privacy-conscious creators and those who want unlimited experimentation without worrying about credit usage. Strengths: The node-based workflow system, introduced in v0.4.0 and expanded in v0.4.1, is a powerful feature that allows you to create complex, repeatable generation pipelines. The Modly Agent and CLI further enable automation, making it ideal for batch processing and integration into existing workflows. The one-click extension system means you can easily swap between different AI models like Hunyuan3D 2, TripoSG, and Trellis2, and even add your own. The open-source nature (MIT license) means the entire codebase is inspectable and modifiable. Weaknesses: The tool is not for everyone. It requires a relatively powerful NVIDIA GPU (6GB VRAM minimum), and Apple Silicon support is limited. The learning curve for the node editor and extension system might be steep for casual users. The output quality varies by model and may require post-processing for production use, so it's not a one-click solution for high-poly assets. Where it fits: Indie game developers who need quick base assets, 3D printing enthusiasts who want to turn photos into STL files, and privacy-focused creators who refuse to upload images to the cloud. Where it doesn't fit: Users without a compatible GPU, teams needing cloud collaboration, or those who prefer a turnkey SaaS experience without any setup.

Real-world workflow fit

Concrete scenarios for the personas Modly actually fits — and what changes day-one when you adopt it.

Indie game developer

You have character concept art and need a base 3D model to prototype in Unity.

Outcome: Install Modly, add the Hunyuan3D 2 extension, import the image, generate a mesh in minutes, then export as GLB directly into your Unity project.

3D printing enthusiast

You captured a photo of a small object and want to create a printable STL file.

Outcome: Open Modly, load the photo, generate a mesh, refine it with a remesh node if needed, export as STL, and import into your slicer—all without uploading anything to the cloud.

Automation-focused developer

You need to generate 3D assets in bulk from a set of images for a project.

Outcome: Create a node workflow with a loop, run it via the Modly Agent or CLI, and generate hundreds of models without manual intervention, saved directly to your workspace.

Limitations

  • Modly runs all inference locally on an NVIDIA GPU, so a compatible GPU is required and there is no cloud fallback.
  • The desktop app is available for Windows, Linux, and macOS, and can also be run from source.
  • It is a desktop application with no API, though a CLI is available in recent versions.
  • The node-based workflow editor and model extension system may have a learning curve, and output quality varies by model and may require post-processing for production use.

Ideal for

Anyone with an NVIDIA GPU who wants unlimited, private 3D generation at zero cost; perfect for hobbyists, indie devs, and privacy-focused creators.

What this tier adds

This is the only tier and includes all features: unlimited local generation, offline operation, node workflow editor, Modly Agent, CLI, and one-click extensions—all free forever.

Hidden costs & gotchas

What the public pricing page doesn't put in bold. Captured from pricing-page footnotes, contract terms, and recurring complaints.

  • You'll need a powerful NVIDIA GPU (6GB VRAM minimum) to run Modly smoothly, which is a hardware cost not included in the free software.
  • While the app is free, installing extensions like Hunyuan3D 2 may require downloading large model files, which consume significant disk space and bandwidth.
  • Time cost: setting up and learning the node-based workflow editor and extension system takes effort that could be spent on actual asset creation in a cloud tool.

Where the pricing makes sense

The company stage and team size where Modly's pricing actually pencils out — and where peers do it cheaper.

Modly is completely free and open source, which makes it the cheapest option among AI 3D generation tools. Cloud competitors like Meshy or CSM charge $20–60 per month with credit limits. While Modly requires a capable GPU, the software itself costs nothing, and for users already owning such hardware, it offers unlimited generation with no recurring fees.

Setup time & first value

How long it actually takes to get something useful out of Modly — broken out by persona, not the marketing-page minute.

For a first-time user with an NVIDIA GPU: install the app, download an extension (e.g., Hunyuan3D 2), and generate your first model in about 10–15 minutes. For developers wanting to set up custom workflows or run from source, expect 1–2 hours to get familiar with the node editor and CLI.

Switching to or from Modly

How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.

Migrating in
  • From Meshy or CSM: Download Modly, install an extension, and import your existing images. There's no direct migration path, but you can start generating locally immediately and export in the same formats you used in
  • From using raw Python scripts: Since Modly is open source, you can inspect the code and adapt your existing scripts to use the Modly CLI or node workflows for more structured generation.
Migrating out
  • To Meshy or CSM: Export your Modly-generated models in standard formats like GLB or OBJ, then upload them to the cloud service. Keep in mind you'll lose local privacy and face usage limits.
  • To Blender or other DCC tools: Export from Modly as GLB or OBJ and import directly into your 3D software for further refinement.
