GPUI Component — Rust GUI Kit

Introduction

GPUI Component provides a comprehensive set of pre-built UI widgets for the GPUI rendering framework. It brings production-ready buttons, inputs, tables, modals, and more to Rust desktop development.

What GPUI Component Does

• Provides 40+ ready-to-use UI components (buttons, inputs, dropdowns, tables, modals)
• Renders at native speed using GPU-accelerated drawing via GPUI
• Supports light and dark themes with a flexible theming system
• Handles keyboard navigation and focus management
• Works on macOS, Linux, and Windows

Architecture Overview

GPUI Component is a pure-Rust library built on GPUI, a GPU-accelerated UI framework originally created for the Zed editor. Each component is a composable Rust struct implementing GPUI view traits. The theming layer uses a token-based design system where colors, spacing, and typography are centralized.

Self-Hosting & Configuration

• Add the crate as a Git dependency in Cargo.toml
• Requires Rust nightly and platform-specific GPUI prerequisites
• Themes are configured by providing a custom ThemeColors struct
• Components accept builder-pattern configuration
• Example apps in the repository demonstrate usage patterns

Key Features

• GPU-accelerated rendering for smooth 120fps interfaces
• Comprehensive component library for desktop UI patterns
• Token-based theming with built-in light and dark modes
• Composable architecture for custom components
• Active development aligned with the GPUI framework

Comparison with Similar Tools

• egui — Immediate-mode and browser-portable; GPUI Component is retained-mode with richer design
• Iced — Elm architecture; GPUI Component uses a view-model pattern closer to native toolkits
• Dioxus — Targets web and desktop via HTML-like syntax; GPUI Component renders directly to GPU
• GTK/Qt bindings — Mature ecosystems but require FFI; GPUI Component is pure Rust

FAQ

Q: Is GPUI the same framework used by Zed? A: Yes. GPUI was created for the Zed code editor.

Q: Does it work on Windows? A: Yes, though macOS has the most mature support.

Q: Can I use it for web applications? A: No. GPUI Component targets native desktop only.

Q: How stable is the API? A: Evolving alongside GPUI. Expect breaking changes before 1.0.
