Native SDK.

Native SDK

Native SDK is a complete toolkit for building native desktop and mobile applications using declarative markup and Zig. Unlike frameworks that rely on embedded browsers or WebViews, Native SDK renders directly to real OS windows through its own engine—delivering sub-100ms launch times and binaries under 6 MB while maintaining expressive, customizable UI design.

Product Highlights

• True Native Rendering: Every interface is drawn by Native SDK's own engine into real OS windows—no WebView, no embedded browser, no heavy runtime overhead.
• Minimal Binary Size: Complete apps compile to static release binaries as small as 3.5 MB, with zero interpreters, parsers, or script engines bundled.
• Cross-Platform Codebase: One codebase compiles for macOS, Linux, Windows, iOS, and Android, with mature desktop support and experimental mobile capabilities.
• Predictable State Architecture: Events produce messages, messages update state, and state renders the interface—making apps simple to debug, maintain, and generate with AI assistance.
• Live Development Workflow: Edit markup while your app runs with hot reloading, keeping state intact and accelerating iteration cycles.
• Built-In Automation: Every app embeds an automation server enabling AI agents to snapshot, assert, click, and screenshot running windows for reliable testing and generation.

Use Cases

• Internal Tools & Dashboards: Build lightweight, fast-launching applications for team workflows, system monitoring, and data visualization without the resource overhead of electron-based alternatives.
• Creative Software: Develop music players, media editors, and design tools with custom chrome, hardware-inspired aesthetics, and responsive native performance.
• Markdown & Document Editors: Create split-pane editors with live native widget previews—rendering headings, tables, and task lists as true OS-native components rather than HTML.
• AI-Assisted Development: Leverage declarative markup and typed update functions to enable reliable code generation by LLM agents, with built-in scaffolding and evaluation harnesses.
• Cross-Platform Utilities: Ship single-binary applications that feel native on every desktop platform while maintaining consistent behavior and appearance through design tokens.

Target Audience

Native SDK is designed for developers who want the productivity of modern declarative UI frameworks without sacrificing native performance—particularly those building tools, creative applications, and internal software where startup speed, binary size, and platform authenticity matter. It also serves teams exploring AI-assisted development workflows who need predictable, inspectable state management that agents can reliably generate and manipulate.
