- Download the Windows build from getartcraft.com (official source only).
- Run the installer or unzip the package — it is a native Rust binary, no runtime required.
- Open the app, create a document or open a real file (e.g. .psd in PhotoCraft, .svg in VectorCraft).
- No account, no signup, no subscription — the family has none.
GPU compositing runs through wgpu (DX12/Vulkan). A GPU with a supported driver helps; it is not mandatory.
Based on the project's stated rendering stack (wgpu: Metal/Vulkan/DX12/WebGPU; WASM browser builds). The project publishes no hard minimum specs.

Edit without destroying the original
LightCraft is an open-source, non-destructive photo editor, part of the ArtCraft family rebuilt in pure Rust. Non-destructive is the core promise: adjustments live as editable steps on top of the original image rather than being baked in, so nothing is ever permanently destroyed by an edit.
It is positioned as a free, clean-room take on the Lightroom-style workflow — the photo-library-and-adjustments model that photographers know — and ships natively for macOS, Windows and Linux with a WebAssembly browser build. Like its siblings it exposes a CLI, JSON control channel and MCP server for scripting and agent-driven edits.
Key facts at a glance
- Non-destructive editing — adjustments are editable steps, the original is never destroyed
- Lightroom-style library and adjustment workflow, free and open source
- Native macOS, Windows and Linux builds plus WebAssembly browser version
- Agent-native: CLI, JSON control channel and MCP server
- Part of the ArtCraft family — one install, one format ecosystem
Quick start — first five minutes
- Download LightCraft from getartcraft.com (macOS, Windows, Linux) or use the browser build — free, no subscription.
- Import a photo into the library and open it in the editor.
- Apply adjustments — exposure, tone, color — as non-destructive steps; the original file stays untouched.
- Compare before/after and reorder or edit adjustment steps anytime.
- Export the processed image; script batch adjustments via CLI/JSON/MCP for consistent looks across a shoot.
Common uses
- Process a shoot with non-destructive adjustments, free
- Keep originals untouched while experimenting with looks
- Batch-apply a consistent grade across a set of photos via scripts
- Learn Lightroom-style editing on a free tool
Non-destructive as a design principle
Destructive editing bakes mistakes into pixels. LightCraft keeps every adjustment as a reorderable, editable step over the original — the model Lightroom users know. You can revisit a grade from last month and change it without starting over.
Batch with one consistent look
The family's CLI/JSON/MCP surface means a shoot's worth of photos can take the same adjustment stack through a script — reproducible looks across an entire set, which is exactly where non-destructive models shine.
Honest gaps
Alpha-stage, like its siblings. The project does not claim Lightroom parity — expect missing library features, catalog management depth and advanced print workflows. For editing individual photos non-destructively it is usable today.
