Why AtomJS?

AtomJS was built from the idea that UI frameworks should be powerful, but also clear and predictable.

Modern frameworks like React and Vue dominate front-end development, but both come with tradeoffs:

React gives developers flexibility, but has grown increasingly complex with hooks, context, and meta-layers that can feel abstract and confusing.
Vue makes things approachable, but often hides important details behind reactive magic, which can make debugging or scaling harder.

AtomJS takes a different path:

The Philosophy of AtomJS

Class-based components — AtomJS embraces a class-driven API, where components are explicit, self-contained, and easy to extend.
Explicit over implicit — no hidden reactivity layers or magical behaviors. What you write is what runs.
Lightweight core — a virtual DOM, JSX runtime, and DOM rendering utilities without unnecessary extras.
TypeScript first — built with TypeScript from the ground up for strong typing and great developer experience.
Simplicity — designed so you can read the source, understand it, and build confidently.

React developers who want a simpler, more class-oriented API.
Vue developers who appreciate simplicity but want more control and transparency.
Framework explorers who enjoy understanding how things work under the hood.
Teams that value TypeScript, predictability, and long-term maintainability.

AtomJS is still young — but growing fast.
Right now, the focus is on the core runtime: rendering, JSX support, and component basics.
