Postshot vs WebODM

Postshot is a Windows application from Jawset for reconstructing photorealistic 3D scenes and objects from photos or video with radiance field technology. Its workflow covers tracking, training, editing, and rendering, with image masking, region-of-interest training, scene merging, and model sequence rendering. Inputs include JPG, PNG, TIF, EXR, DNG, and RAW images plus MOV, MP4, and MKV video. Exports are PLY, SPZ, and HTML, and integrations include Unreal Engine and After Effects. Free supports COLMAP and RealityScan camera and point imports. The Free plan allows unlimited image count, video length, and model size, with output up to 4K SDR (8-bit) for non-commercial use. Indie adds watermark-free renders, commercial use, floating licensing, and PLY/SPZ export. Studio adds further formats, above-4K and HDR output, command-line use, and AprilTag alignment. Free costs nothing; Indie and Studio are also listed at free.

WebODM turns aerial images into georeferenced maps, point clouds, digital elevation models, textured 3D models, and Gaussian splats. It accepts photos or videos from any drone, including JPG, TIFF, video files, and multispectral imagery, and can run on a user's computer while offline. Exports include GeoTIFF, PNG, LAS/LAZ, OBJ, and OGC 3D Tiles. Mapping tools cover measurements, plant-health indexes, ground-control points, elevation contours, rolling-shutter correction, and sharing links. WebODM uses ODX, a free, open-source photogrammetry engine that developers can run from the command line or integrate into software. It can also connect to processing nodes that speak the NodeODX API. The API uses token authentication through the /api/token-auth/ endpoint, with tokens expiring after six hours by default. Model-level and row-level permissions govern whether users can view, add, edit, or delete objects. WebODM is free to install and use locally; optional cloud plans are listed at $24 a month billed yearly for Starter, $35 a month billed yearly for Pro, and $99 a month billed yearly for Business. Minimum requirements are 8 GB RAM and 20 GB disk space; larger datasets have higher recommended requirements.
