The picks
3 open source · ranked by fit
- 01
darktable
open sourceGPL-3.0+Local13kaug 2026A mature RAW darkroom with lens profiles, masks, denoise, and non-destructive edits; the interface still expects homework.
The catch vs DxO PhotoLabIts local denoise and lens corrections are capable, but they do not equal DxO's DeepPRIME processing and laboratory-measured Optics Modules for supported camera and lens pairs.
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 newer packaged RAW editor with lens correction, denoise, masks, and GPU edits; quicker to learn, less battle-tested than darktable.
The catch vs DxO PhotoLabIts denoise, masks, and lens correction are promising, but far less mature and broadly profiled than DxO's DeepPRIME and Optics Modules.
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

RawTherapee
open sourceGPL-3.0Local4.1kjul 2026Excellent RAW development, optical correction, detail recovery, and profiles, with fewer catalog features and zero hand-holding.
The catch vs DxO PhotoLabIt offers excellent manual RAW control, but not DxO's DeepPRIME neural noise reduction or automatically matched laboratory camera and lens corrections.

- Original RAW files remain unchanged; processing settings are saved as human-readable .pp3 sidecars beside the image or in the local cache, and rendered exports go to a chosen folder
