The projects I’m actively building and improving.

GPUI Kit

☆ 14.2k stars

Fast, polished native apps in Rust.

Since 2024, I’ve been building and maintaining GPUI Kit, a desktop application framework built on GPUI, formerly known as GPUI Component.

It brings UI components, layouts, editors, and application development tools together for macOS, Windows, and Linux. My work on GPUI’s core includes MSAA path anti-aliasing, linear gradients, Tab focus navigation, and vector path construction, alongside the application layer I continue to build in GPUI Kit.

Interfaces
Components, data tables, docking, and charts for building desktop interfaces.
Applications
A code editor and application tools, used in native apps such as Longbridge Pro.
Extensions
GPUI Shell lets applications support plugins and extensions written in JavaScript.

Contributions

I contribute improvements from real projects back to the tools and frameworks I build on—from Rails and GitLab to Rust desktop software.

Zed & GPUI

Since February 2024, I’ve contributed more than 100 merged PRs to Zed and GPUI, spanning the editor, its rendering framework, and native platform integration. Much of this work connects the needs of Zed with what I learn building Longbridge Pro and GPUI Kit.

  • Graphics and rendering. Helped lay the foundation for arbitrary path drawing in GPUI through vector path construction, MSAA anti-aliasing, and a reworked path renderer. Together, these provide the groundwork for custom vector graphics and chart rendering, with smoother edges and lower GPU memory overhead.
  • Text and typography. Improved CJK wrapping, multi-line truncation, font rendering, and interactive text styles—making text more reliable across layouts and states.
  • Interaction and performance. Added keyboard focus navigation and activation, and improved view caching to reduce unnecessary rendering during scrolling and mouse interaction.
  • Native platforms and editor experience. Improved Windows integration and macOS rendering, alongside everyday Zed workflows such as theme switching, file navigation, and terminal tasks.

I’m also developing proposals for native window composition, GPUI overlays above native child views, and glass-surface rendering. These are ongoing upstream proposals, extending how GPUI works with embedded native content.

Zed featured my work in Community Champion Spotlight: Jason Lee, recognizing my contributions to both the framework and its wider ecosystem.

“… outstanding contributions to gpui and the ecosystem around it.”
