Instant
Instant is a real-time backend as a service and relational graph database designed to synchronize data across clients automatically. It functions as a data synchronization layer that provides authentication, permissions, and relational data storage for web and mobile applications.
The platform includes an optimistic UI framework that updates local interfaces immediately during writes and handles automatic server rollbacks. It also features a real-time presence system to broadcast transient user states, such as cursor positions and online status, to other connected clients.
The system manages data consistency through a client-side cache for offline persistence and real-time relational synchronization. Security is handled via role-based access control to manage record visibility and modification rights at the server level.
Local development and testing are supported through container-based orchestration to deploy a local server environment.
Features
- Graph-Relational Databases - Implements a relational graph database that synchronizes structured data across clients in real time.
- Real-time Data Synchronization - Automatically synchronizes relational data changes from the server to all connected clients in real time.
- Backend-as-a-Service Platforms - Provides a comprehensive cloud platform integrating relational database synchronization, authentication, and permission management.
- Client-Side Storage - Uses a client-side storage mechanism to persist application data and enable offline functionality.
- Offline Caching - Provides local data persistence to keep applications functional during network outages with automatic synchronization upon reconnection.
- Offline-First Persistence - Implements an offline-first pattern that caches data locally and synchronizes changes once connectivity is restored.
- Role-Based Access Control - Secures data at the server level by filtering record visibility and modification rights based on user roles.
- User Access Management - Manages user permissions and record visibility to ensure authorized access to relational data.
- Optimistic UI Orchestrators - Provides an orchestration layer that gives instant UI feedback while managing background persistence and state rollbacks.
- Optimistic UI Updates - Updates the local interface immediately during data writes and automatically rolls back changes on server failure.
- Optimistic Update Engines - Implements a mechanism for immediate local state changes with automatic server-driven rollbacks to ensure a responsive user experience.
- Presence Broadcasters - Streams transient user activity states like cursor positions through low-latency channels to synchronize presence.
- Collaborative Presence States - Tracks and broadcasts transient user states such as online status and cursor positions to synchronize collaborative activity.
- Presence Tracking - Tracks and broadcasts real-time user activity and online status to coordinate presence in collaborative applications.
- Data & Databases - Management of modern serverless database applications
