GPUI Kit
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.

gpui-kit The one crate applications depend on
├── gpui-base Unstyled behavior, state, and infrastructure
└── gpui-component GPUI Component: the complete styled UI system
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; gpui-component-shell supplies the styled catalog.
See the executable application recipe and AI-assisted development acceptance checks for a tested starting point and verification commands.
- 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.
