Features

Every screenshot here is the real app at work on public-domain art, rendered offscreen through its control channel.

Levels and Vibrance adjustment layers, with the live Histogram panel.Impression, Sunrise, Claude Monet, 1872 Edit without regret Adjustment layers keep every edit live. Stack Levels, Curves, Vibrance, Hue/Saturation and a dozen more, mask them to an area, reorder them, or turn them off, and your original pixels never change. 16 adjustment layers that also apply directly to pixels, including Curves with per-channel editing, Levels with a live histogram, Black & White, Channel Mixer, Gradient Map, Photo Filter, Selective Color and Color Lookup (.cube, .3dl, .look).

PSD without compromise

PhotoCraft's PSD support is a standalone crate written from Adobe's public specification and tested against a corpus of real-world files.

• Faithful round trips: opening and re-saving a document renders the same for 307 of the 309 files in the psd-tools test set and 169 of 170 in our mixed ag-psd/psd-tools set (crates/io/tests/it/corpus.r
• Pixels that match: a composite oracle compares our render with Photoshop's own merged image, covering gradient interpolation (Classic, Perceptual and Linear), layer effects, shape strokes, clipping an
• Large documents: PSB, 16 and 32-bit files, and CMYK and Lab documents open natively.

Under the hood

• Engine first: a pure-data document model and a command engine, with a thin egui UI on top. Layering is enforced at build time across 24 crates.
• Two compositors: a CPU compositor serves as the reference oracle, and a wgpu compositor puts the canvas on the GPU. They are tested against each other.
• Copy-on-write tiles: 256² sparse tiles make undo cheap and huge canvases light, and effect maps are cached per layer state.
• Runs in the browser: the whole engine and UI compile to WebAssembly.
• Clean-room: implemented from public specs and observed behaviour only. No proprietary code, shaders or assets.
• Tested: more than 1,700 tests, including PSD round trips, synthetic generators, compositor oracles and multi-depth checks.

概述

Image editing; an open-source, clean-room reimplementation of Adobe Photoshop, rebuilt in pure Rust. Layers, masks, adjustment layers, layer styles, type, vectors, brushes and real PSD files, in a native app written entirely in Rust. Open source, offline, and yours.

🎛️ Familiar by design The menus, shortcuts, panels and tools are where your hands expect them, from ⌘J to ⇧⌘D. If you know Photoshop, you already know PhotoCraft. ⚡ Native and fast A GPU compositor on wgpu (Metal, Vulkan, DX12, WebGPU), copy-on-write tiles and multithreaded filters. No Electron, no web view, no waiting. 🗂️ Real PSD files Open, edit and save layered Photoshop documents. Re-saving keeps the render of 307 of the 309 psd-tools test files. 🤖 Agent-ready Every action is a command, so you can drive the same engine from the UI, the CLI, a JSON control channel or an MCP server.
