OpenReco

OpenReco is desktop photogrammetry software for turning drone and camera images into 3D models and mapping outputs. It is best suited to people who need reconstruction plus geospatial measurement or vegetation analysis; its open-source, no-subscription approach makes it a practical fit for that workflow.

Its breadth of exports and stage-by-stage processing are compelling, though the GPU-oriented reconstruction path and desktop-only deployment make it less suited to users seeking a web or mobile workflow.

Overview

OpenReco builds dense point clouds, textured meshes, orthomosaics, and elevation models from imagery. Its node-based workspace can run a complete reconstruction graph or individual stages, with cached results that support reproducible work. That flexibility is valuable when a project needs selective reruns, rather than repeating every processing stage.

COLMAP CUDA provides GPU multi-view stereo, with an automatic CPU fallback. The fallback broadens hardware compatibility, but users without a suitable GPU should expect the reconstruction path to rely on CPU processing instead.

Key features

Georeferencing and analysis

Models can be georeferenced from EXIF GPS or ground control points. For mapping and survey work, that connects image reconstruction to spatial reference rather than leaving outputs as unlocated 3D models. Measurement tools cover volume, profile, area, and distance; NDVI, ExG, and VARI maps add vegetation analysis for agriculture and forestry work.

Export formats

Exports include LAS and LAZ point clouds, PLY and OBJ models, GeoTIFF orthomosaics, GeoJSON, DXF, CSV, 3D Tiles, and contour SHP. This range makes OpenReco relevant to both GIS-oriented workflows and 3D content work, while the specific output format can be chosen for the next tool or deliverable.

Pricing

OpenReco is free: the Free plan costs nothing. It requires no account or subscription, and the MIT license makes it open source. There is no paid tier to weigh against a free cap or seat limit; the trade-off is that OpenReco is a desktop application, not a hosted service.

Platforms

OpenReco is a desktop app with downloads for Windows, macOS, and Linux. It supports orthophoto and point-cloud exports, ground control points, GIS data export, and API access. Its listed platform range suits desktop users across the major operating systems, but not readers looking for browser or mobile access.

Who it's for

OpenReco is aimed at surveying and mapping, agriculture and forestry, VFX and heritage, construction and earthworks, and robotics and research. The combination of georeferencing, measurements, vegetation indices, and broad export formats is most useful to people who need outputs beyond a textured model. It is a less natural choice for users who only want a lightweight image-to-3D tool or need a web-based workflow.

Pros and cons

Pros

• Reproducible, selective processing: the node graph can run end to end or stage by stage, and cached results avoid treating every run as a fresh start.
• Useful mapping and analysis tools: ground control points, spatial measurements, and vegetation maps extend the workflow beyond reconstruction.
• Wide export coverage: point clouds, GIS data, mesh formats, and 3D Tiles address varied downstream needs.
• No-cost open-source access: the MIT license and lack of account or subscription requirements remove payment and signup barriers.

Cons

• Desktop-only: there is no listed web or mobile platform for users who need to process or review work away from a desktop.
• GPU-first reconstruction: COLMAP CUDA is the primary multi-view stereo path; CPU fallback helps with compatibility but may not suit users prioritizing GPU-free processing.

Alternatives

For other options, see Photogrammetry Software.

• WebODM is a strong alternative for users who want a free local, offline workflow or web and API platform choices; paid Starter is $24 a month, billed yearly, for 12 maps per 30.
• 3DF Zephyr suits Windows users who want a personal-use free tier capped at 50 photos or video frames, with a single GPU and limited exports and editing.
• Agisoft Metashape is worth considering for users seeking a paid, node-locked license with a free trial; its Standard Edition is $179 a month.
• OpenDroneMap is another free option for Linux, macOS, Windows, or self-hosted use; its Standard plan costs $64, paid once and includes one year of installation support, updates, a per-user license, and a 30-day money-back guarantee.
• 3Dsurvey may suit readers who need Android or iOS alongside desktop and web platforms; its yearly subscription license is €187.50 a year, billed yearly in the amount of 2,250 €, excl. taxes.
• RealityScan is an alternative for readers who want a freemium option spanning Android, iOS, Linux, and Windows.
• PHOTOMOD is an alternative for readers considering a platform range that includes self-hosted and web deployment.
• KIRI Engine is an alternative for readers who prefer Android, iOS, or web access and a free Basic tier of up to 150 photos per scan.

Verdict

Choose OpenReco if you need desktop photogrammetry with georeferencing, practical measurement and vegetation tools, and exports that cover both GIS and 3D work, without a subscription. Its main reason to look elsewhere is deployment: users who need browser or mobile access should choose a platform built around those workflows instead.
