Top Recommended Replacements
Darktable
FREEBest Overall FOSS Alternative
Why we like it
Professional RAW developer; non-destructive workflow; powerful masking and 'filmic' tone mapping that rivals high-end editors.
Keep in mind
Steep learning curve; lacks 'one-click' AI automation like sky replacement.
Pixlr (Express/AI)
FREEBest for AI Sky Replacement
Why we like it
Browser-based; features a dedicated 'Sky Changer' and 'AI Generative Fill' similar to Luminar's logic; very easy to use.
Keep in mind
The free version is ad-supported and has daily export limits.
Krita (with Generative AI Plugin)
Best for Creative VFX
Why we like it
Powerful painting and photo tool; when paired with the 'Stable Diffusion' plugin, it can generate or replace backgrounds and objects for free.
Keep in mind
Requires a separate plugin installation for AI features; interface is tailored more for artists than photographers.
RawTherapee
Best for Detail & Sharpness
Why we like it
Incredible control over RAW demosaicing; includes advanced 'Retinex' algorithms for HDR-like lighting recovery.
Keep in mind
No 'Portrait AI' or 'Sky AI' features; interface is very technical and data-heavy.
DigiKam
Best for Photo Management
Why we like it
Advanced AI-driven face detection and tagging; robust batch processing tools for organizing massive libraries.
Keep in mind
AI is focused on organization/metadata rather than creative 'looks' or filters.
Upscayl
Best for Image Restoration
Why we like it
Specialized AI for upscaling and cleaning up low-quality photos; results are often cleaner than Luminar’s built-in upscaler.
Keep in mind
Single-purpose tool; does not handle color grading or sky replacement.
BeFunky (Free Edition)
FREEBest for Beginners
Why we like it
Includes 'Auto Enhance' and basic AI retouching; works in-browser with zero installation.
Keep in mind
High-end AI tools (like Sky Replacer) are often locked behind a premium paywall.
LightZone
Best for Exposure Control
Why we like it
Unique 'Zone System' approach to lighting; excellent for dramatic black and white or landscape edits.
Keep in mind
The UI feels dated; development speed is slower than modern alternatives.
Photopea
FREEBest Web-Based Alternative
Why we like it
A complete Photoshop clone in the browser; supports PSD files; includes AI-driven 'Magic Cut' for background removal.
Keep in mind
Ad-supported; lacks the specific 'Landscape AI' templates found in Luminar.
GIMP (with G'MIC-Qt)
Best for Feature Depth
Why we like it
The G'MIC plugin adds hundreds of filters, including skin smoothing and artistic transfers that mimic Luminar's filters.
Keep in mind
Non-destructive editing is not as seamless as in Luminar or Darktable.
OpenArt AI (Web)
FREEBest for AI Background Swaps
Why we like it
Modern web tool for 'Sky Replacement' and 'Background Changing' using the latest Stable Diffusion models.
Keep in mind
Requires credits for some operations; requires an internet connection.
Icecream Photo Editor
FREEBest Lightweight Option
Why we like it
Very simple, clean interface; great for quick filters, resizing, and adding text/overlays.
Keep in mind
Lacks professional RAW support or advanced AI features.
