The picks
3 open source · ranked by fit
- 01
darktable
open sourceGPL-3.0+Local13kaug 2026Catalog, RAW development, masks, effects, lens profiles, and batch export in one mature desktop app; expect knobs, many knobs.
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.
Install, platforms & data +
- platforms
- desktopone-click install
- install
- Install the Windows executable, macOS disk image, Linux package, Flatpak, or AppImage
- setup
- macOS may require a Gatekeeper right-click Open or xattr step; the larger obstacle is learning darktable's module-heavy workflow rather than installation
- engines
- A local non-generative imaging pipeline; current releases can use ONNX models for subject masking, denoising, and image upscaling without a cloud account
- your data
- Original 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

RapidRAW
open sourceAGPL-3.0Local9.2kaug 2026A friendlier new RAW editor with a library, ratings, culling, masks, presets, and denoise; not yet as deep or proven.
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.
Install, platforms & data +
- platforms
- desktopmobileone-click install
- install
- Install the Windows .exe, macOS .dmg, or Linux AppImage/DEB/Flatpak; Android is an experimental sideload
- setup
- Desktop binaries are unsigned, so Windows SmartScreen and macOS Gatekeeper need manual bypass steps; Linux AppImage users may also need libfuse2
- engines
- Local subject, sky, and foreground masking, NIND denoising, LaMa inpainting, and optional handoff to a user-run ComfyUI backend
- your data
- Photos 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

digiKam
open sourceGPL-2.0+Local32aug 2026A formidable local catalog with RAW import, ratings, tags, duplicates, batch tools, and an editor; prettier workflows were not invited.
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.
Install, platforms & data +
- platforms
- desktopone-click install
- install
- Install the Windows installer/portable build, macOS package, or a Linux AppImage, Flatpak, Snap, or distribution package
- setup
- First-run collection and database choices are technical, and scanning a large library plus downloading recognition models can take a long time
- engines
- Local OpenCV and packaged machine-learning models for face recognition, automatic tagging, image-quality scoring, similarity search, red-eye detection, and related catalog analysis
- your data
- Photos 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
