The fine-grained reactive open source framework for building lightning-fast apps — no virtual DOM, no JSX, no transpilation.
Why Sigment?
React With JSX
function App() {
return (<div>Hello World!</div>);
}Sigment (No JSX)
function App() {
return div('Hello World!');
}⚙️ Sigment is built without a virtual DOM or JSX. It uses real DOM operations and plain JavaScript functions, allowing you to write clean, modern code with zero build tools.
- ✅ Clean code: No mixing of HTML inside JavaScript
- ⚡ Short & readable: Less boilerplate and fewer lines of code
- 🚀 Faster compile time: JSX adds a transpile step — Sigment skips it
⚡ Fine-Grained Reactivity
Only the parts that need to change update — no diffing, no overhead.
🚫 No Virtual DOM
Sigment updates the DOM directly, making your UI faster and simpler.
📦 Ultra-Lightweight
A minimal runtime and zero config setup means less to worry about.
🧠 Developer Friendly
Built for modern developers — readable syntax, powerful tools, and no need for build steps.
🛠 No JSX, No Transpiler
Just write JavaScript — tag functions like div() and button() build your DOM directly.
