A new compile-time UI framework called Gea promises to deliver the fastest reactive web development experience yet. Built on the philosophy that JavaScript alone is enough, Gea eliminates the need for virtual DOM, hooks, signals, or compiler directives. Instead, it analyzes JSX at build time to create surgical DOM updates that directly mutate only the elements that change.

Weighing in at just ~13 kb gzipped with router, Gea achieves its speed through zero-runtime overhead. The framework compiles ordinary JavaScript classes and functions into reactive components, with stores implemented as Proxy-wrapped classes that support deep mutations. This approach means developers don't need to learn new concepts—everything works like standard JavaScript, with the compiler handling reactivity automatically.

Gea comes as a complete toolkit including a client-side router, 35+ accessible UI components built on Zag.js, mobile primitives, and VS Code extension support. The framework also ships with AI agent skills for tools like Cursor and Codex, enabling AI-assisted development. With MIT licensing and a one-command setup via npm, Gea positions itself as a zero-dependency alternative to established frameworks like Solid, Svelte, Vue, and React.
