ChudoPaint is a community-built, cross-platform raster image editor. It aims to provide a familiar Paint-like workflow with a capable layer system, while remaining fast, approachable, and open source.

Status: early foundation. The first milestone establishes the Tauri + React application, quality gates, and contributor workflow. The editor itself is not available yet.

• Run natively on Windows, macOS (Intel and Apple Silicon), and Linux.
• Build an accessible raster editor for everyday image work.
• Support transparent layers, PNG import/export, drawing tools, and undo/redo.
• Keep the editor core independent from the React UI where practical.
• Make decisions and development welcoming to contributors.

The initial scope and future milestones are documented in Docs/Plan.md.

• Tauri 2 and Rust for the desktop shell and native operations
• React and TypeScript for the interface
• Vite for frontend development and builds

Install the following before developing locally:

• Node.js 22 or newer
• Rust stable toolchain
• Tauri's platform-specific prerequisites from the official guide

On Linux, install the required WebKitGTK development packages for your distribution.

npm install
npm run tauri dev

Useful checks:

npm run format
npm run lint
npm run typecheck
cargo fmt --manifest-path src-tauri/Cargo.toml -- --check
cargo clippy --manifest-path src-tauri/Cargo.toml -- -D warnings

Create a distributable package locally with:

npm run tauri build
