4 open-source Photoshop clones built with AI in 2026
The counterargument to AI-assisted development used to be simple: where is the Photoshop replacement? Complex, layer-heavy, format-dependent software was supposed to be the ceiling that one-shot app generation could never clear.
As of October 2026, that argument is gone. Developer and writer André Klein has been tracking viable Photoshop alternatives and found not one but four candidates, three of them fully open source. He tested each against the same PSD file to check layer fidelity, Smart Object handling, blend modes, and color accuracy.
️ The Four Candidates
Photon Studio is the most polished of the group. It’s not open source, but it’s free and ships binaries for macOS, Windows, and Linux. It loaded and saved Klein’s test PSDs without issues, with Smart Objects, blend modes, and layer effects fully intact. It also supports local AI models and integrations with agentic workflows.
OmaPhoto is a Linux port of Compositor by Wonder Assembly. It imported the test PSD and was transparent about unsupported features. Downsides: it flattened Smart Objects, lost some adjustment layers, and leans on its own .comp format rather than PSD, so round-tripping back to Photoshop is awkward for now.
PhotoCraft is a clean-room Photoshop reimplementation written in pure Rust. It imported the test PSD and preserved Smart Objects without flattening them, though editing Smart Objects did not work as expected. Color adjustments came through with some interpretation issues that Photopea, the pre-AI web-based benchmark for PSD parity, does not have. PSD export worked fine.
PhotoSuite is another open-source entry promising 1:1 native PSD/PSB compatibility. Klein called it the closest to Photoshop in terms of UI parity. Colors imported mostly clean. Smart Object creation worked, but editing them (which requires double-click to open in a new tab in Photoshop) did not.
Also Worth Watching
Klein also noted two more projects in an update: Patchy by Seth Robinson (open source, runs in browser, handled color adjustment layers and Smart Objects cleanly in his tests) and Xuan by silverling (a Rust port of Compositor, untested at the time of writing).
The Operator Takeaway
If you pay for Photoshop and your workflow is not deeply tied to proprietary Adobe features, these projects are worth a serious look right now. Photon Studio is the safest drop-in today given its PSD fidelity. PhotoSuite is the closest on UI. All three open-source options are moving fast, and bugs that exist today are the kind that get patched in days, not months.
