Zed GPUI

A hardware-accelerated UI framework for building high-performance desktop applications in Rust.

GPUI is the rendering engine behind the Zed editor, designed to bypass the overhead of traditional web-based shells by leveraging the GPU directly. It treats the UI as a scene graph, utilizing Metal on macOS and Vulkan or DX12 on other platforms to achieve consistent 120 FPS performance. By integrating Rust's memory safety with a custom layout engine and text shaper, GPUI enables developers to build complex interfaces that maintain low latency and a minimal memory footprint (often under 100MB for the entire application).
