FigCraft

Interface design; an open-source, clean-room reimplementation of Figma, rebuilt in pure Rust.
Frames, auto layout, components and variants, vector networks, styles, variables and prototypes,
in a native app that opens instantly and works offline. Open source, and yours.

FigCraft on getartcraft.com · ArtCraft · All Crafting Apps

[!NOTE] ArtCraft is a community of artists from all walks of life. Designers, illustrators, developers, musicians, game makers — if you make things, you're one of us. Come say hi on Discord.

🎛️ Familiar by design

The toolbar, layers panel, Design panel, menus and shortcuts sit where your hands expect them. If you know Figma, you already know FigCraft.

⚡ Native and fast

A Rust engine with a persistent document model: edits touch only what changed, so creating a node in a 20,000-node file takes a fraction of a millisecond. No Electron, no web view.

🔌 Offline and private

Your files are plain .figcraft archives on your own disk. No account, no cloud, no telemetry. SVG, PNG, JPG, WebP and PDF in and out.

🤖 Agent-ready

Every menu item, tool and drag is a command, so the same engine runs from the UI, the CLI, a JSON control channel or an MCP server.

Features

Layouts that build themselves Auto layout in both directions, with wrap and grid, padding, gaps, alignment, Hug / Fill / Fixed sizing, min and max sizes, absolute positioning, and drag handles for padding and spacing right on the canvas. Constraints and layout grids for everything else.	Components that scale Main components, instances with overrides that survive edits, component sets with variants, properties, swap instance, detach, reset overrides and go to main component. Local styles and variables (colour, number, string, boolean) with modes.
Vectors without compromise Real vector networks: the Pen and Pencil tools, vector edit mode with bend, split, heal-on-delete and handle mirroring, boolean groups (union, subtract, intersect, exclude), flatten, outline stroke, arrowheads, dashes and per-side strokes. Rectangles with smooth (squircle) corners, polygons, stars and arcs.	Paints and effects Solid, linear, radial, angular and diamond gradients with on-canvas handles, image fills (fill, fit, crop, tile), multiple fills and strokes, every blend mode, drop and inner shadows, layer and background blur, masks.
Type that sets beautifully Text edited in place on the canvas, mixed styles within a paragraph, auto width and auto height, line height, letter and paragraph spacing, decoration, case and text styles, shaped with HarfRust and the open fonts from craft-fonts plus your system fonts.	Prototype and hand off Connections, triggers, actions and Smart Animate-style transitions, flows and a presentation view. Inspect mode with measurements, CSS and SVG. Export any layer at any scale to PNG, JPG, WebP, SVG or PDF.

Built for agents

Every menu item, tool and gesture runs a command from one registry of 270+ commands. The UI, the CLI, the JSON control channel and the MCP server all call the same commands, so anything you can click, a script or an AI agent can do too.

# Headless: render and export
figcraft-cli render landing.figcraft -o landing.png --scale 2
figcraft-cli export landing.figcraft -o out/ --format svg

# Run a script of commands without a window
figcraft-cli run build-card.json --out card.figcraft

# Every command, with its parameters
figcraft-cli commands --filter autoLayout

# Let an agent drive it over MCP (headless, or attached to the running app)
figcraft-cli mcp
figcraft-cli mcp --attach 47800

The desktop app also offers a loopback-only control channel (figcraft --control <port>) for inspecting UI state, driving tools with pointer and key events, and taking screenshots. See docs/control-protocol.md, docs/mcp.md and docs/cli.md.

Under the hood

Engine first: a pure-data document model and a command engine, with a thin, swappable egui UI on top. Layering is checked at build time across the workspace crates (cargo xtask layers).
Persistent data: the document lives in an immutable ordered map, so undo snapshots are cheap and layout, component sync and text measurement only revisit what changed.
Its own renderer: tiny-skia on every core for the canvas and exports, with layer blending, effects and masks; booleans from linesweeper, geometry from kurbo, text from skrifa and HarfRust.
Runs in the browser: the whole engine and UI compile to WebAssembly.
Never crashes: no unwrap, expect or panic in shipped code, enforced by clippy; commands run behind a guard so a bug fails one action, not your session.
Clean-room: implemented from public documentation and observed behaviour only. No proprietary code, file formats, icons or images.

Get started

git clone https://github.com/storytold/figcraft
cd figcraft
cargo run --release -p figcraft            # the desktop app
cargo test --workspace                     # the test suite
cargo xtask ci                             # fmt, clippy, tests, layering and asset checks

Fonts for the UI and the Text tool come from craft-fonts, cloned next to this repository (../craft-fonts); without it FigCraft falls back to your system fonts.

git clone https://github.com/storytold/craft-fonts ../craft-fonts

For the web build, install trunk and run cargo xtask wasm.

New contributors and AI agents: start with AGENTS.md, then docs/.

Installers for macOS (universal, signed and notarized), Windows (x64, x86 and arm64), Linux (AppImage, .deb, .rpm, Flatpak and tarball), FreeBSD and the web are attached to each GitHub release. Maintainers: docs/releasing.md explains how releases are built, signed and published.

[!IMPORTANT] Status: FigCraft is in early alpha. Most of Figma's editor surface exists in some form, and the main menu is almost fully wired (docs/parity.md), but that measures wiring, not behaviour. Multiplayer, comments, version history, plugins and Dev Mode depth are not there yet. The honest, area-by-area picture is in the roadmap. Expect rough edges and please file issues, or tell us what broke on Discord.

The Crafting Apps

FigCraft is one of the Crafting Apps: free, open-source creative tools from the ArtCraft team, each written from scratch in Rust and each able to stand on its own.

And ArtCraft itself, our AI image and video studio for artists who want real control.

The Crafting Apps share the same conventions: clean-room and pure Rust, native on macOS, Windows, Linux and FreeBSD, in the browser via WebAssembly, and fully drivable by agents.

Come make things with us

Our Discord is where people who make things hang out: designers sketching their first app, developers who just want a button to look right, illustrators, filmmakers, type nerds, and plenty of people still working out what they like to make. Share what you're building, ask for help, tell us what's broken or what you wish FigCraft could do. You're welcome here.
