How we chose these Affinity Photo alternatives

We looked for open-source tools that overlap with Affinity Photo's core: editing photos with layers, retouching, and RAW development. We verified each project's license, recent activity, stars, releases, and platforms in its repository. Only a few mature projects fit, and they split between layer-based editing and RAW processing. We left out one tool listed elsewhere because we could not find a working repository for it. See our methodology for the full criteria.

Important: no single tool does everything

GIMP handles layer-based photo manipulation, painting, and graphic design with scripting and plugins, but it lacks some professional features such as non-destructive adjustment layers across the board and a modern RAW pipeline. darktable and RawTherapee develop RAW files but are not general-purpose editors.

Closest to Affinity Photo

GIMP is the closest for pixel editing, layers, and retouching on Linux, macOS, and Windows. Pair it with darktable or RawTherapee for RAW development to approach Affinity Photo's all-in-one workflow, since GIMP's RAW import relies on external converters.

RAW workflow tools

darktable combines a library of photos, non-destructive RAW development, professional color management, and GPU acceleration. RawTherapee uses a 32-bit floating-point engine with advanced demosaicing and multi-frame processing. Neither provides cloud sync or mobile apps.

License details

GIMP is GPL-3.0-or-later, and darktable and RawTherapee are GPL-3.0.

Maintenance status

GIMP, darktable, and RawTherapee all had commits within days of this update. GIMP is developed on GNOME's GitLab, and the GitHub repository is a mirror.

Why look for a Affinity Photo alternative?

Affinity Photo is proprietary software sold as a license, and its maker is now owned by Canva, so its future and pricing are tied to that company. Open-source alternatives are free, run on Linux, macOS, and Windows, use open file formats and plugins, and have no license fee, at the cost of a steeper learning curve and less polish in some workflows.
