No frameworks. No build tools. Just JavaScript with superpowers.

Fine-Grained Reactivity

Update only what changes. No virtual DOM. No diffing. Just precise, surgical DOM updates exactly where they're needed.

🧠

Built entirely on native JavaScript. What you already know is what you use—no new paradigms to learn.

🧩

State, effects, collections, forms—use only what you need. Compose primitives to build exactly what your app requires.

🔍

Nothing hidden. See exactly when and how the DOM updates. Understand reactivity by reading simple, clear source code.

🚀

Drop it in with a script tag or bundle it with your build process—your choice, your workflow.

🌱

Learn reactivity by understanding it, not memorizing framework abstractions. Build intuition that transfers anywhere.
