Native Shell (NSH)

Native SDK is an open-source toolkit for building native desktop applications. It uses declarative markup in `.native` files for views, plain TypeScript compiled to native code at build time or Zig for application logic, and an engine that renders directly into real operating-system windows without a browser, WebView, or JavaScript runtime in the application binary. The CLI can scaffold, run, check, and build applications, with live view updates during development and an optimized release-binary build. Its component catalog includes controls such as buttons, tabs, text fields, dialogs, charts, and virtual lists, while styling is organized around replaceable design tokens. The toolkit also includes an embedded automation server for agents.

shadcn/ui is an open-source collection of accessible UI components and a code distribution platform for building custom component libraries. It distributes component source code directly into consuming projects, where developers can customize, extend, and build on the components across supported web frameworks. Documentation is available at ui.shadcn.com/docs, and the project is licensed under the MIT license.

Looseleaf is a React, Tailwind v4, and Radix component library with a shadcn registry, making accessible interface components look hand-drawn on paper. It provides 123 components, 61 layout blocks, coded icons and illustrations, stickers and stamps, a sketchpad, a chat kit, and the Kevin Sans typeface. Components retain shadcn/ui parts, props, and data-slot names, and can be added to a project with the shadcn CLI; the generated source is copied into the application rather than installed as a dependency. Its drawing layer places an SVG behind the real DOM label. Seeded TypeScript recipes generate the artwork with CSS-variable colors, while pre-drawn layers controlled by CSS handle hover, press, and focus states. The library includes accessibility features such as keyboard support, visible focus, reduced motion, forced colors, RTL, text contrast, target sizing, and multiple density options. The code, artwork, and Kevin Sans are licensed under MIT; IBM Plex Mono is licensed under SIL Open Font License 1.1. The project is developed and distributed through its GitHub repository, documentation site, and shadcn registry.

OpenShell is an open-source runtime from NVIDIA and a structural safety safeguard for running fleets of autonomous AI agents in isolated sandboxes, complementing model-based policy checks. It lets agents read files, install packages, call APIs, and use credentials while enforcing declared filesystem, process, and network policies. Each agent runs in a sandbox where kernel-level controls govern file access, system calls, and network connections. OpenShell also uses formal verification to review policy changes before approval, flagging newly permitted access such as connections to additional hosts with credentials or calls to new API methods. Credentials are withheld from agents and added only to requests bound for approved endpoints. The project provides a CLI, local gateway, sandbox lifecycle management, policy tooling, inference-provider routing, Kubernetes deployment, extensibility APIs, and Python, TypeScript, Go, and Rust SDKs.

GPUI Kit is an open-source Rust framework for building cross-platform desktop applications with GPUI. It provides a single dependency that re-exports the matching GPUI release, base infrastructure, styled components, and assets. Its architecture separates gpui-base for unstyled behavior, state, and infrastructure; gpui-component for the complete styled UI system; and gpui-shell for JavaScript extensions hosted by a Rust application. The project includes more than 75 documented components and primitives, data tables, virtual lists, a code editor, dock layouts, Markdown and HTML rendering, syntax highlighting, and charts. Applications can target macOS, Windows, Linux, and WebAssembly. The interaction layer includes AccessKit accessibility support, while its UI integration tests render components in headless windows and exercise pointer and keyboard input while checking state, focus, layout, and accessibility. The repository includes a component showcase and standalone examples, including dock layouts, editors, Markdown, and HTML rendering.
