Top 5 Real-Time Databases Compared
Blog post from Convex
The comparison of five real-time databases highlights their strengths, limitations, and ideal use cases, aiding developers in selecting the most suitable platform for their applications. Convex is favored for full-stack JavaScript/TypeScript projects requiring real-time synchronization and consistency, especially with React or Next.js, while Firebase Realtime Database is ideal for MVPs and prototypes needing lightweight sync, though it lacks ACID transactions. Supabase offers a familiar SQL-based environment with PostgreSQL, but may experience update lags under load, and Realm caters to offline-first mobile apps with local storage and cloud sync capabilities. InfluxDB is designed for time-series data, excelling in fast ingestion and analytics, but is not suited for CRUD apps or reactive UIs. The choice of a real-time database should align with the specific needs of the development team and the application's goals, with the flexibility to migrate if requirements evolve.
