## What it is
Cerebral is a declarative state and side effects management library for JavaScript frontend frameworks like React, Vue, Angular, Preact, and Inferno. It models application logic as composable sequences of actions and ships with a debugger offering time-travel inspection of state and sequences.

## Use cases
- manage state in a React app with declarative side effect sequences
- time-travel debug application state changes
- share state management logic across React, Vue, and Angular
- structure complex async flows as composable action chains
- organize a frontend app into modules with scoped state
- add typed state management to a Vue 3 application

## When to choose
- you want declarative, composable sequences instead of imperative async logic
- you need a debugger with time-travel for state and side effects
- you work across multiple view frameworks and want one state pattern
- you value full type safety in state management

## When to avoid
- you want a library with active feature development - it is in maintenance mode
- your team already uses Redux, Zustand, or Pinia conventions
- you need a large ecosystem of middleware and community extensions
- you prefer minimal unopinionated state containers
