ON1 Photo RAW alternatives: 7 open-source picks
These 7 ON1 Photo RAW alternatives replace it for $0, led by darktable, RapidRAW and digiKam. All 7 are open source. License, stars and last commit checked by hand on 2026-08-29. No trials, no crippled tiers.
Catalog, RAW development, masks, effects, lens profiles, and batch export in one mature desktop app; expect knobs, many knobs.
licenseGPL-3.0+
runson your machine
installInstall the Windows executable, macOS disk image, Linux package, Flatpak, or AppImage
enginesA local non-generative imaging pipeline; current releases can use ONNX models for subject masking, denoising, and image upscaling without a cloud account
dataOriginal photos stay untouched; edits, ratings, tags, and history are stored in a local SQLite library and portable XMP sidecar files, with thumbnails and cache data in the user profile
the catch vs ON1 Photo RAWIt matches the darkroom fundamentals, but lacks ON1's polished one-click AI effects, generative tools, bundled creative presets, and extension marketplace.
setupmacOS may require a Gatekeeper right-click Open or xattr step; the larger obstacle is learning darktable's module-heavy workflow rather than installation

A friendlier new RAW editor with a library, ratings, culling, masks, presets, and denoise; not yet as deep or proven.
licenseAGPL-3.0
runson your machine
installInstall the Windows .exe, macOS .dmg, or Linux AppImage/DEB/Flatpak; Android is an experimental sideload
enginesLocal subject, sky, and foreground masking, NIND denoising, LaMa inpainting, and optional handoff to a user-run ComfyUI backend
dataPhotos are never moved; non-destructive adjustments are stored in a documented .rrdata sidecar next to each image, while thumbnails, logs, and downloaded models live in local application data
the catch vs ON1 Photo RAWIt offers a cleaner core RAW workflow, but fewer mature effects and generative tools, no comparable asset-extension ecosystem, and a much shorter track record.
setupDesktop binaries are unsigned, so Windows SmartScreen and macOS Gatekeeper need manual bypass steps; Linux AppImage users may also need libfuse2

A formidable local catalog with RAW import, ratings, tags, duplicates, batch tools, and an editor; prettier workflows were not invited.
licenseGPL-2.0+
runson your machine
installInstall the Windows installer/portable build, macOS package, or a Linux AppImage, Flatpak, Snap, or distribution package
enginesLocal OpenCV and packaged machine-learning models for face recognition, automatic tagging, image-quality scoring, similarity search, red-eye detection, and related catalog analysis
dataPhotos 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
the catch vs ON1 Photo RAWIts organization is stronger than its editor, so ON1's masks, effects, retouching, and integrated AI tools remain a large gap.
setupFirst-run collection and database choices are technical, and scanning a large library plus downloading recognition models can take a long time
