GPUI Kit 
English | 简体中文
Build fantastic, high-performance desktop apps with Rust and GPUI.
GPUI Kit is a comprehensive Rust desktop application framework. It combines a
production-ready UI system with application-grade data, layout, and editing
capabilities, all built on a reusable foundation of behavior, state, and
infrastructure. GPUI Kit ships 75+ documented components and primitives,
WebAssembly support, AccessKit accessibility, UI integration testing, and an
optional JavaScript extension runtime.

 [code] 
`gpui-kit` pins the matching GPUI release and re-exports GPUI, base, component,
and assets, so a Rust application lists a single dependency. JavaScript extension
hosts add `gpui-shell` separately; its default `components` feature supplies the styled catalog.
See the executable application recipe and AI-assisted development acceptance checks for a tested starting point and verification commands.
## Features
- **75+ Components and Primitives**: Forms, navigation, overlays, data display, editing, feedback, and layout, with polished interactions and productive defaults.
- **Production Ready**: Used to build Longbridge Pro from day one and continuously refined in a publicly shipped commercial desktop application.
- **WebAssembly**: Run applications and the same component showcases on the web with `wasm32-unknown-unknown`.
- **Accessibility**: AccessKit roles, names, states, relationships, and actions are built into the interaction layer and covered by tests.
- **UI Integration Testing**: Render real components in headless windows, drive pointer and keyboard input, and assert state, focus, layout, and accessibility.
- **Native Feel**: Modern controls inspired by macOS and Windows, backed by semantic themes and multiple sizes.
- **120 FPS**: GPU-accelerated interfaces that remain smooth under load.
- **Data Tables**: Virtual scrolling, fixed and resizable columns, sorting, and cell selection across hundreds of thousands of rows.
- **Virtual Lists**: Render only the visible range, including lists whose items have different sizes.
- **Code Editor**: Stable performance at 200K lines with Tree-sitter highlighting and LSP diagnostics, completion, and hover.
- **Dock Layout**: Resizable panels, draggable tabs, nested splits, and edge docks — all serializable.
- **Rich Content**: Native Markdown and HTML rendering, syntax highlighting, and built-in charts.
- **Design Freedom**: Use the complete visual system or build your own on the behavior and infrastructure in `gpui-base`.
- **JavaScript Extensions**: `gpui-shell` lets a shipped Rust host load panels and business logic as scripts, with every capability granted explicitly.
- **Cross Platform**: Ship one Rust codebase to macOS, Windows, and Linux.
## Framework Architecture
### Three layers. One ecosystem.
Use `gpui-component` to keep the application coherent with one complete visual
and interaction system. Use `gpui-base` when your product needs to create and
own that system itself. Use
