Modly
Modly is a free, MIT-licensed local AI 3D model generator that turns a photo or text prompt into a textured mesh on your own GPU.
If you have the GPU, Modly is the most useful free route to image- and text-to-3D available — unlimited local runs, zero uploads, and node workflows that let you batch assets instead of clicking through models one at a time. The extension catalog is what separates it from other local generators: Hunyuan3D 2, TripoSG, and Trellis2 let you swap models rather than commit to one. Bring patience for post-processing and VRAM headroom.

Skip Modly if you don't have a capable NVIDIA GPU and want to pay per render instead — there's no cloud fallback, and Apple Silicon is a caveated path rather than a first-class one.
Unlimited generation is free, but a large batch run occupies your GPU for hours — the real cost is your electricity bill and a machine you can't use meanwhile.
Modly is free under the MIT license — no credits, no subscription, no per-render charge — which makes it cheaper than any paid cloud 3D generator over any horizon. The true cost is hardware: a capable NVIDIA GPU, or Apple Silicon with the caveats noted from v0.4.0. Against subscription tools you're effectively trading a monthly fee for a machine you own, so it wins decisively for anyone generating at volume and loses for anyone without the GPU already.
In short
Modly — Modly is a free, MIT-licensed local AI 3D model generator that turns a photo or text prompt into a textured mesh on your own GPU. Best for Indie game developers turning concept art into base meshes for props and environments, 3D printing hobbyists converting photos into printable STL files, Artists who want a starting mesh to refine in Blender or ZBrush. Free to use.

About Modly
Modly is a free, open-source desktop app that generates textured 3D meshes from a single image or a text prompt, with all inference running on your own GPU. Nothing gets uploaded — your reference photos and prompts stay on your machine, and there are no credits, queues, or per-render caps to track. Output exports as GLB, OBJ, STL, or PLY and drops straight into Blender, Unity, Unreal, or a slicer for 3D printing. The engine is modular by design. Generation runs through one-click extensions, each a GitHub repository bundling an open-source model — Hunyuan3D 2, TripoSG, and Trellis2 are named on the site, with balanced, fast, and high-fidelity variants you pick per job. Install from the in-app catalog or paste any GitHub URL. Modly also ships a node-based workflow editor with While Loop and For Each iterator nodes, the Modly Agent for automated pipelines, an agent-friendly CLI for scripted and headless batch runs, a Gaussian Splat viewer, a transform gizmo, and a workspace asset library with collections. The v0.4.x line is where the app matured: v0.4.0 added the node workflow system, v0.4.1 brought workflow loop nodes and a native macOS build, and v0.4.2 added a shared CUDA/MPS/CPU device-selection helper plus extension model-registration validation. Windows (.exe), Linux (AppImage/.deb), and macOS (.dmg) installers are all published, or you can clone and run from source. It fits indie game developers turning concept art into base meshes, 3D printing hobbyists converting photos into printable STLs, and privacy-minded creators who refuse to upload reference images. The costs are hardware and polish: you need a capable GPU, and the app assumes a tinkerer's mindset rather than a turnkey SaaS one. Against cloud options like Meshy or CSM, you trade a subscription for your own silicon.
Behind the Verdict
Reach for Modly when the bottleneck is cost or privacy, not quality. Indie devs blocking out props and terrain from concept art, hobbyists turning phone photos into STLs, and anyone who won't send unreleased art to a hosted service all get real value here — the generation is local, unlimited, and MIT-licensed, so you can script it, fork it, or wire it into a build pipeline without asking permission. The workflow layer is the part people underrate. Loop nodes plus the CLI mean you can point Modly at a folder of reference images overnight and wake up to a library of meshes, which is a different job than clicking Generate on one photo in a browser tab. If your work is batch-shaped, that alone justifies the install. Where it bites: this is not a render-farm replacement. High-poly, production-clean assets still want retopo and cleanup in Blender or ZBrush, and the app expects you to understand model choice — balanced versus fast versus high-fidelity is a real quality/time tradeoff, not a label. Hardware is the other gate. NVIDIA GPUs are the primary path; Apple Silicon works but the project's own materials frame it as the newer, more caveated route. Compared with Meshy or CSM, you give up convenience and a support channel, and you gain no per-render billing and no upload step. Compared with other local 3D generators, Modly's edge isn't a single model — it's that the extension system lets the model underneath change without changing your workflow. Pass if you need cloud sharing, real-time collaboration, or a zero-setup experience for a non-technical teammate. Also pass if you're on integrated graphics or a laptop with little VRAM; the install will work and the results will disappoint.

Real-world workflow fit
Concrete scenarios for the personas Modly actually fits — and what changes day-one when you adopt it.
Drop character concept art into Modly, pick Trellis2 for fidelity, generate a textured GLB, then wire a node workflow that runs a folder of sketches through the same pipeline overnight.
Outcome: A shelf of base meshes ready to import into Unity or Unreal the next morning, with no per-render cost and no images leaving the machine.
Photograph an object on a phone, feed the image to Modly on a gaming PC, and export STL.
Outcome: A printable mesh in minutes rather than hours of modelling from scratch, with the photo never uploaded to a service.
Install Modly's CLI and call it from a script, or hit the /workflow-runs surface for headless operation, to regenerate assets whenever source art changes.
Outcome: 3D asset generation becomes a step in the build rather than a manual task, with the Modly Agent handling repeated runs.
Use Cases
- Turn a photo of a product prototype into a 3D mesh for quick design iteration
- Convert character concept art into a GLB asset for Unity or Unreal prototyping

- Package an open-source image-to-3D model as a Modly extension for your own catalog
Models Under the Hood
as of 2026-10-16
Limitations
- All inference runs locally on the user's GPU, so a capable NVIDIA GPU is required (Windows and Linux are the advertised download platforms), with no cloud fallback.
- Capabilities depend on which open-source extension model you install (Hunyuan3D 2, TripoSG, Trellis2), and the docs note that clean input gives the best results.
- Extensions are GitHub repositories bundling third-party model pipelines (manifest.json, generator.py), so users run externally authored code.
- The next release (0.5) is framed as 'coming next' on the roadmap, so those features are not yet shipped.

What this tier adds
Starting tier and the only tier — MIT-licensed, unlimited generation, no credits or subscriptions, with all extensions and languages to PLY included.
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 free under the MIT license — no credits, no subscription, no per-render charge — which makes it cheaper than any paid cloud 3D generator over any horizon. The true cost is hardware: a capable NVIDIA GPU, or Apple Silicon with the caveats noted from v0.4.0. Against subscription tools you're effectively trading a monthly fee for a machine you own, so it wins decisively for anyone generating at volume and loses for anyone without the GPU already.
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.
Windows or Linux: download the .exe or AppImage/.deb, install, then add an extension from the catalog — first mesh in roughly 15–30 minutes, longer if drivers or model weights need downloading. Building from source (git clone, npm install, npm run dev) adds significant time. macOS and Apple Silicon users should budget extra for MPS caveats.
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.
- →From Meshy: export or re-source your reference images, install Modly, add the Hunyuan3D 2 or Trellis2 extension, and regenerate locally — there's no credit meter on the other side.
- →From CSM: move your reference photos into a Modly workspace collection and batch them through a node workflow instead of one upload at a time.
- →From a manual Blender blockout: install Modly alongside Blender, generate base meshes from reference images, and refine them in your existing scene.
- ↗To Meshy or CSM: export GLB from Modly, upload the mesh, and continue refinement in the cloud if you need sharing or collaboration.
- ↗To Blender or ZBrush: export GLB, OBJ, or PLY and retopologize or sculpt the base mesh to production quality.
- ↗To a slicer: export STL directly from Modly and open it in your slicer for print preparation.
