Native SDK

v0.5.3

Native SDK is a toolkit designed for building high-performance, native desktop applications using declarative UI and a TypeScript-based logic model. It replaces heavy web-based runtimes with a custom engine that draws directly to OS windows, ensuring native performance without relying on browsers or WebView.

Native rendering engine with no browser or WebView overhead

Declarative markup and TypeScript/Zig core for logic

Deterministic state management with record and replay capabilities

Zero

Zero is a systems programming language built by Vercel Labs specifically for AI agents. It features explicit effects, predictable memory, and structured compiler output — making it small, fast, and easy for agents to use, understand, and repair code.

Explicit effects system — agents know exactly what a program can do, with no hidden side effects

Structured compiler output — JSON diagnostics and typed safe fixes so agents can parse errors and apply reliable repairs

Small native tools with predictable memory — compiles to native executables with zero runtime overhead
