title: Signals Overview
description: An extremely lightweight and blazing fast fine-grain reactivity system for React.
package: 'signals'

## What is Signals?

The architectural landscape of frontend state management in 2026 reflects a
fundamental tension between React’s top-down, component-based reconciliation model
and the industry’s growing demand for fine-grained, localized reactivity. While
React continues to dominate the enterprise ecosystem, powering over 79 million
websites worldwide, its reliance on the Virtual DOM (VDOM) for state synchronization
introduces inherent performance bottlenecks at scale.

Cerberus Signals fills the gap that current external libraries have missed by
creating a fine-grained, ultra-lightweight, approach that out-performs in all areas
with an easy to use DX to provide full control and flexibility where you need.

## Installation


```bash
npm install @cerberus/signals@npm:@cerberus-design/signals
```


### Dependency Requirements

The Signals library only requires the use of React to be installed in your project.

## React

Our Signals library was built to ensure compatibility with React compiler and the
19+ API design. We have APIs that support both client and server rendering to meet
whichever need your use case might have.

## Typescript

Signals is built with typescript and provides additional meaningful type exports
in addition to the APIs. If any demo requires the use of the `use client` directive
you will see it displayed in the code preview.

## Server-side Rendering

Any API which uses the `createX` naming convention is server-side compatible.
Client-focused APIs are designed primarily as hooks to improve the developer experience
and overall understanding.
