Plattformenon your machine
InstallationInstall the Windows installer/portable build, macOS package, or a Linux AppImage, Flatpak, Snap, or distribution package
ModelleLocal OpenCV and packaged machine-learning models for face recognition, automatic tagging, image-quality scoring, similarity search, red-eye detection, and related catalog analysis
DatenPhotos remain in selected local or network collection folders; catalog, thumbnails, faces, and similarity data live in SQLite by default or MariaDB, with metadata and ratings optionally written into files or XMP sidecars
EinrichtungFirst-run collection and database choices are technical, and scanning a large library plus downloading recognition models can take a long time
facts verified 2026-08-10
A mature local and network catalog with metadata, ratings, RAW import, batch tools, and a serviceable editor.
the catchIt is a capable catalog, not a professional tethered-capture and studio-session editor comparable to Capture One.
the verdict →all Capture One alternatives →
Excellent local photo cataloging, metadata, tags, duplicates, RAW handling, and basic edits; elegance was not in the requirements.
the catchIts catalog is excellent, but its RAW-development, masking, and polished color workflow are substantially weaker than Lightroom's.
the verdict →all Adobe Lightroom alternatives →
Duplicate search, similarity tools, aesthetic detection, pick labels, and metadata export in a mature desktop catalog; setup is less friendly.
the catchIts duplicate, similarity, and quality tools are useful, but they are less purpose-built and less personalized than Aftershoot's photographer-focused AI culling.
the verdict →all Aftershoot alternatives →
A formidable local catalog with RAW import, ratings, tags, duplicates, batch tools, and an editor; prettier workflows were not invited.
the catchIts organization is stronger than its editor, so ON1's masks, effects, retouching, and integrated AI tools remain a large gap.
the verdict →all ON1 Photo RAW alternatives →last updated 2026-08-10 · up to $828/yr replaced · no votes, no pay-to-list
