darktable

open sourcedesktopone-click install

Reusable styles, presets, history, sidecars, and fully reversible local adjustments; it learns nothing about your taste, which is both flaw and feature.

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 Imagen AIStyles and presets are deterministic rather than learned from the photographer's prior edits, so they cannot adapt each image in the personalized way Imagen does.

setupmacOS may require a Gatekeeper right-click Open or xattr step; the larger obstacle is learning darktable's module-heavy workflow rather than installation

R

RapidRAW

open sourcedesktopmobileone-click install

Non-destructive presets, masks, batch edits, and local processing in a modern app; no personalized AI style model, no recurring bill.

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 Imagen AIIts presets and masks stay reversible, but it does not train a personal editing profile or adapt batch decisions to each photograph.

setupDesktop binaries are unsigned, so Windows SmartScreen and macOS Gatekeeper need manual bypass steps; Linux AppImage users may also need libfuse2

RawTherapee

open sourcedesktopone-click install

Processing profiles and sidecars make repeatable RAW adjustments completely reversible; automation is deterministic, not psychic.

licenseGPL-3.0

runson your machine

installInstall the Windows installer, macOS disk image, or Linux AppImage/distribution package

dataOriginal 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

setup✓ installs clean

the catch vs Imagen AIProcessing profiles repeat exact settings, but they do not learn taste or make image-specific personalized adjustments the way Imagen does.

why people still pay for Imagen AI

People still pay for Imagen AI because photographers pay because image quality, catalog safety, and fast handling of huge libraries matter more than cloning sliders. The recurring cost buys raw codecs, color management, metadata, previews, face models, GPU support, storage, backups, sync, and export fidelity, not just the visible interface.
