1. Nerfstudio – Best Open Source NeRF Tool

Price: Free
Offline Use: Yes
Export Types: NeRF scene, camera paths, mesh (via plugins)
Best For: Developers, AI researchers, technical 3D artists

Nerfstudio has become one of the most robust and transparent alternatives to Luma AI.

It’s fully open-source and is backed by a fast-growing GitHub community. You can train NeRF models, render 3D environments, control depth, and even generate camera flythroughs—all without relying on a third-party server.

I use this when I need full control and a transparent pipeline. It’s not plug-and-play, but if you know Python and have a decent GPU, it’s a game-changer.

2. Polycam – Best All-Rounder

Price: From $7.99/month or $69.99/year
Offline Use: Yes (Pro version)
Export Types: OBJ, GLTF, FBX, USDZ
Best For: Creators who need speed and polish

Polycam supports LiDAR, photogrammetry, and NeRF—all in one package.

It works on iOS, Android, and the web. The Pro plan includes powerful export options and offline photogrammetry support.

I really like using Polycam for fast mobile captures. It’s also great when I need a quick 3D asset and don’t want to mess with code or rendering backends.

3. Kiri Engine – Best for Android Users

Price: Free with paid Pro at $6.99/month
Offline Use: Yes (Pro feature)
Export Types: OBJ, STL, GLB
Best For: Android users and mobile creators

If you’re not on iOS, Kiri Engine is a go-to photogrammetry app. It doesn’t use NeRF, but it still produces decent mesh models with full textures.

The app is reliable, clean, and supports offline processing.

I found this tool incredibly useful when testing Android workflows and asset creation for smaller projects.

4. RealityScan – Best for Professionals

Price: From $99/month
Offline Use: Yes
Export Types: OBJ, FBX, PLY
Best For: Game studios, VFX pipelines, architecture

RealityScan is a photogrammetry powerhouse used in AAA game studios and VFX. Owned by Epic Games, it’s extremely fast and delivers ultra-detailed geometry and textures.

I’ve used RealityScan on high-end workstations to scan environments with thousands of images, and the results are some of the best in the industry.

5. Kaedim – Best for Game Devs

Price: Starts at $150/month
Offline Use: No
Export Types: FBX, OBJ
Best For: Game developers, concept artists

Kaedim uses AI to generate 3D meshes from 2D concept art. It’s not a scanner or NeRF app, but it’s a strong alternative for people who want to generate stylized assets fast without modeling from scratch.

When I need quick base meshes for prototyping in Unity, Kaedim saves hours.

6. Trnio – Best for Beginners

Price: $4.99 (one-time App Store purchase)
Offline Use: No
Export Types: OBJ
Best For: Quick captures, students, hobbyists

Trnio is a super simple mobile app that turns photos into 3D scans. It’s limited in depth and resolution, but for basic objects or rough concepts, it does the job well.

I recommend this to anyone starting out with 3D and looking for a low-cost intro to photogrammetry.

7. Meshroom – Best Free Photogrammetry Tool

Price: Free
Offline Use: Yes
Export Types: OBJ, PLY
Best For: Developers, tinkerers, open-source fans

Meshroom is a free, offline photogrammetry suite built on AliceVision. It’s completely open source and gives you full control over reconstruction steps like depth maps and texture mapping.

If you don’t mind waiting for long render times and enjoy tweaking settings, this is a great free alternative.

Final Verdict: Which Luma AI Alternative Is Best?

After testing each tool hands-on, here’s how I’d recommend choosing:

Use Case	Best Tool
Developers and Technical Users	Nerfstudio
Mobile Creators	Polycam or Kiri
Game Developers	Kaedim
Professional Studios	RealityCapture
Beginners	Trnio or Polycam
Open-Source Fans	Meshroom

Every tool has its pros and trade-offs. For me, Nerfstudio is where I go when I need precision and transparency, while Polycam is my quick go-to on the move.

If you’re just starting out, don’t worry about picking the most advanced or expensive tool right away.

Most creators evolve into their tools over time. Start with what matches your current workflow and budget.

You can always switch as your projects get more ambitious. What matters is finding a tool that gives you consistent results without creating friction in your creative process.
