Propeller Aero Alternatives: 12 Options Compared, Including Free (2026)

What is Agisoft Metashape?

Agisoft Metashape builds dense point clouds, meshes, textures and survey-ready orthomosaics from photo sets, and is generally treated as the accuracy benchmark in this category. Its dense reconstruction offers configurable depth filtering and detailed control over each processing stage, which ...

What is RealityCapture?

RealityCapture, from Capturing Reality and owned by Epic Games, is a photogrammetry engine built around GPU-accelerated dense reconstruction, and its defining characteristic is speed — it processes very large image sets substantially faster than CPU-bound alternatives, which is what matters ...

What is PhotoModeler?

PhotoModeler is a long-established photogrammetry product built around measurement accuracy rather than visual output. It is used in accident reconstruction and forensics, structural and industrial inspection, and archaeology — applications where the deliverable is a defensible dimension, not a ...

What is KIRI Engine?

KIRI Engine is a mobile and web 3D scanning application supporting photo-based photogrammetry, LiDAR capture and 3D Gaussian splatting, with cloud processing and export to standard formats. It includes an object-capture mode with automatic background removal, which removes the tedious masking ...

What is Luma AI?

Luma AI captures 3D scenes using neural radiance fields and Gaussian splatting rather than classical photogrammetry, reconstructing a scene from phone video with convincing handling of reflections, transparency and fine detail that mesh-based reconstruction struggles with. The output is a ...

What is Skydio?

Skydio builds autonomous drones and the software that plans and executes capture missions for them. Its relevance to photogrammetry is 3D Scan, which flies a structure autonomously and works out the imagery required for complete reconstruction as it goes, adapting the flight path rather than ...

What is Scaniverse?

Scaniverse is a free mobile 3D scanning app supporting LiDAR and photogrammetric capture with Gaussian splatting, and it processes on the device rather than in the cloud — so scans complete without a connection and the imagery never leaves the phone. It exports to standard formats including ...

What is Correlator3D?

Correlator3D from SimActive processes aerial, satellite and drone imagery into digital surface and terrain models, orthomosaics and 3D models, and is engineered for throughput on very large datasets using GPU acceleration and multi-core processing. It supports imagery from large-format mapping ...

What is Meshroom?

Meshroom is a free, open source photogrammetry application built on the AliceVision computer vision framework. It runs a node-based pipeline where each processing step is visible and can be modified or re-run independently — genuinely useful for learning how photogrammetry works, and for anyone ...

What is 3DF Zephyr?

3DF Zephyr from 3Dflow reconstructs 3D models from photographs and video, covering point cloud generation, meshing, texturing and measurement, with survey and aerial-specific editions above the base product. Its Free edition handles projects up to 50 photos with no watermark or time limit, ...

What is Polycam?

Polycam turns a phone into a 3D scanner, supporting LiDAR capture on compatible iPhones and iPads, photo-based photogrammetry on any device, and Gaussian splat capture. Scans process in the cloud and export to common formats including OBJ, GLTF and USDZ, plus point clouds and floor plans. It ...

What is OpenDroneMap / WebODM?

OpenDroneMap is an open source toolkit that processes aerial imagery into point clouds, orthomosaics, elevation models and textured meshes, with WebODM providing a browser interface and project management on top of it. It can be self-hosted on your own hardware, which means no per-project ...
