Overview

GPUI Kit is a comprehensive Rust desktop application framework designed for building exceptional, high-performance cross-platform applications. It leverages GPUI, a powerful rendering foundation, to deliver a production-ready UI system, robust data handling, advanced layout capabilities, and sophisticated editing features. Built on a reusable core of behavior, state, and infrastructure, GPUI Kit offers a flexible and extensible ecosystem for developers.

Key Features

• Rich Component Library: Over 75 meticulously crafted components and primitives, including forms, navigation, overlays, data displays, and editing tools, all with polished interactions and smart defaults.
• Production-Ready & Battle-Tested: Developed and refined through a commercially shipped desktop application, ensuring stability and reliability.
• Cross-Platform Compatibility: Deploy a single Rust codebase seamlessly across macOS, Windows, and Linux.
• WebAssembly Support: Enables applications and component showcases to run in the browser using wasm32-unknown-unknown.
• Full Accessibility: Integrated AccessKit support ensures applications meet accessibility standards with robust testing.
• Advanced UI Testing: Render components in headless windows, simulate user input, and verify state, focus, layout, and accessibility with integrated UI testing.
• High Performance: GPU-accelerated interfaces achieve 120 FPS for smooth and responsive user experiences, even under heavy load.
• Specialized Components: Includes advanced features like virtual scrolling data tables (handling hundreds of thousands of rows), virtual lists with variable item sizes, and a high-performance code editor with LSP and Tree-sitter integration.
• Flexible Architecture: Offers three distinct layers: gpui-component for complete styled UIs, gpui-base for custom design systems, and gpui-shell for JavaScript-extensible applications.
• Extensibility: Supports JavaScript extensions via gpui-shell, allowing for dynamic panel loading and business logic scripting.
• Native Look and Feel: Modern controls inspired by macOS and Windows, combined with semantic theming and adaptable sizing.

Typical Use Cases

GPUI Kit is ideal for developers building:

• Modern Desktop Applications: Create feature-rich, visually appealing, and highly responsive desktop applications with a native feel.
• Data-Intensive Tools: Develop applications that require efficient handling and display of large datasets, such as system monitors, IDEs, or data analysis tools.
• Complex Editor Experiences: Build sophisticated code editors, rich text editors, or custom IDE components.
• Customizable and Extensible Software: Design applications that can be extended by third-party plugins or custom scripts via the gpui-shell integration.
• Cross-Platform Solutions: Ship a unified application experience across multiple operating systems from a single codebase.
• Design System Development: Leverage gpui-base to construct unique, branded design systems while benefiting from GPUI's core rendering and behavior.
