Convex

Convex rethinks the backend-as-a-service category with a TypeScript-native, reactive database that eliminates the gap between frontend and backend development.

Key Features:

• TypeScript Everywhere - Write backend functions in the same language as your frontend
• Reactive Queries - UI updates automatically when data changes
• ACID Transactions - Full transactional guarantees for data integrity
• File Storage - Built-in file handling with CDN distribution

The Convex difference:

• No API Layer - Call backend functions directly from React components
• Automatic Caching - Optimal data fetching without manual optimization
• Real-time by Default - Subscriptions are the primary pattern, not an add-on
• Scheduled Functions - Cron jobs and delayed execution built in

Convex shines when building real-time, interactive applications. The tight TypeScript integration means type safety from database to UI. For projects where data changes frequently and should reflect immediately, Convex eliminates entire categories of synchronization bugs.
