Laravel Chorus is a real-time synchronization engine designed specifically for Laravel applications. It seamlessly synchronizes subsets of your database to your users’ devices, enabling lightning-fast user interfaces and robust offline capabilities.

​
The Problem Chorus Solves

Traditional web applications require constant server round-trips for data operations, resulting in:
  • Slow user interfaces with loading states for every action
  • Poor offline experience when network connectivity is limited
  • Frustrating delays that break the flow of user interactions
  • Complex state management for real-time features

​
The Chorus Solution

Chorus transforms your application by maintaining a synchronized local copy of relevant data on each client:

Instant Interactions

UI updates immediately without waiting for server responses

Real-time Sync

Changes broadcast instantly to all connected clients

Offline Support

Full functionality even without internet connection

Secure by Design

Built-in data filtering and multi-tenant isolation

​
Key Features

Selective Synchronization - Choose exactly which models and fields to sync with custom filters and multi-tenant isolation. Real-time Broadcasting - Powered by Laravel Reverb for instant WebSocket updates with efficient delta synchronization. Offline-First Architecture - IndexedDB storage with optimistic updates, conflict resolution, and automatic sync when reconnected. Developer Experience - Laravel-native implementation with simple trait-based configuration, React hooks, and TypeScript support.

​
How It Works (Overview)

  1. User performs an action (create, update, delete)
  2. UI updates instantly using optimistic updates
  3. Request sent to server in the background
  4. Server processes and stores changes in database
  5. Change event (harmonic) created and broadcast via WebSocket
  6. All connected clients receive and apply the update
  7. Local IndexedDB synchronized with server state

​
Use Cases

Chorus is perfect for applications requiring instant user feedback and real-time collaboration: messaging platforms, collaborative editing tools, project management dashboards, real-time analytics, social feeds, and ERP systems with live inventory.

​
Performance Benefits

Users see immediate feedback for all actions, eliminating frustrating loading states and creating a native app-like experience.
Fewer database queries as clients work with local data. Server only handles writes and change broadcasts.
Only changes (deltas) are transmitted, not full datasets. Smart caching reduces redundant network requests.
WebSocket connections handle thousands of concurrent users efficiently. Local processing reduces server CPU load.

​
When to Use Chorus

Perfect for applications requiring real-time updates, Personal Apps, instant UI feedback, collaborative features, offline capabilities, and high-frequency user interactions. Not ideal for simple CRUD applications, complex server-side business logic, or extremely sensitive data that shouldn’t be cached locally.
