WordCraft — Open-Source Word Processor (Free, Rust)
Who this is for: Writers, students and office workers who need real document processing without a Microsoft 365 subscription — and want documents that automate cleanly.
Open-source Word in pure Rust — a clean-room reimplementation of the Word processing workflow, free, scriptable, agent-native.
Quick answer: WordCraft is a free, open-source, clean-room reimplementation of the Word processing workflow in pure Rust — document editing from the ArtCraft family, native on macOS/Windows/Linux plus browser, scriptable via CLI/JSON/MCP. Alpha stage with documented gaps.
Official source — WordCraft
getartcraft.com → the app's page → Download for desktop (Windows build)
- 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.

The Word workflow, rebuilt clean
WordCraft is an open-source, clean-room reimplementation of the Word processing workflow, rebuilt in pure Rust. It is the document-editing member of the ArtCraft family — the 'Word' of the suite — positioned as a free alternative to the Microsoft Word workflow.
Like its siblings, WordCraft runs natively on macOS, Windows and Linux with a WebAssembly browser build, and exposes a CLI, JSON control channel and MCP server, so document work can be scripted and driven by AI agents. Family-native file formats keep documents open and diffable.
Key facts at a glance
- Clean-room reimplementation of the Word processing workflow in pure Rust
- Document editing with the family's open, diffable file formats
- Native macOS, Windows and Linux plus WebAssembly browser build
- Agent-native: CLI, JSON control channel and MCP server
- Free, no subscription — part of the ArtCraft family
Quick start — first five minutes
- Download WordCraft from getartcraft.com (macOS, Windows, Linux) or use the browser build — free, no subscription.
- Create a new document and work with standard formatting — headings, styles, lists, tables.
- Open existing documents in the family's open format and continue editing.
- Script document generation (reports, letters, mail-merge style jobs) via CLI/JSON/MCP.
- Export or share — documents stay open and diffable, not trapped in a binary.
Common uses
- Write and format documents without a Microsoft 365 subscription
- Generate documents from scripts or AI agents (reports, letters)
- Keep documents in version control with diffable formats
- Learn Word-style document processing free
Documents that diff
Word files are opaque to version control. WordCraft's open, diffable format means a document is a reviewable artifact: what changed between versions is visible in Git instead of being a mystery. For teams that generate documents from templates, that is a real workflow change.
Generation, not just typing
The CLI, JSON control channel and MCP server make document generation scriptable: reports, letters and template fills can be produced by a script or an AI agent, then opened for final human review.
Honest gaps
Alpha-stage. Full Word feature parity — advanced styles, mail merge depth, track changes, macros — is not claimed. Check the project status before migrating complex client documents.
