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)
- User performs an action (create, update, delete)
- UI updates instantly using optimistic updates
- Request sent to server in the background
- Server processes and stores changes in database
- Change event (harmonic) created and broadcast via WebSocket
- All connected clients receive and apply the update
- 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 e-commerce with live inventory.Performance Benefits
Instant User Experience
Instant User Experience
Users see immediate feedback for all actions, eliminating frustrating loading states and creating a native app-like experience.
Reduced Server Load
Reduced Server Load
Fewer database queries as clients work with local data. Server only handles writes and change broadcasts.
Bandwidth Efficiency
Bandwidth Efficiency
Only changes (deltas) are transmitted, not full datasets. Smart caching reduces redundant network requests.
Scalable Architecture
Scalable Architecture
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.Ready to get started?
