FirebaseBuild Apps Faster with Google's Platform are the best for Real-Time Databases. So, let’s take a closer look at all 4 tools.
Convex is a backend platform that gives you everything needed to build modern web and mobile applications. It includes a real-time database, serverless functions, file storage, and built-in features like authentication and scheduling. Unlike traditional backend setups, Convex updates your app automatically whenever data changes, without requiring complex code.
The platform is built around TypeScript, which means you get full type safety from your frontend to your backend. This reduces errors and makes development faster. Convex also includes vector search for AI applications, webhooks for integrations, and components that add functionality with simple commands.
There is a free plan for individual developers and small projects, plus paid plans for teams that need more resources and support. Self-hosting is also possible with the open-source version.
Supabase is a complete backend platform that gives you all the tools needed to build modern applications. At its core is a Postgres database, which is known for being stable and feature-rich. You can store data, create tables, and manage relationships without writing complex code.
Beyond the database, Supabase includes user authentication with support for email, social logins, and phone numbers. It also has file storage for images and documents, real-time features for live updates, and edge functions to run custom code. Everything connects through simple APIs that are automatically created from your database structure.
What makes Supabase different is that it is completely open-source. You can host it yourself or use their cloud service, and you never get locked into their platform.
Firebase is a cloud-based platform that provides backend services for applications. Think of it as a complete toolkit that handles everything your app needs on the server side. Instead of building your own servers, databases, and authentication systems from scratch, Firebase gives you ready-to-use services.
The platform includes a real-time database where your app data updates instantly across all devices. It has user authentication that works with email, phone numbers, Google, Facebook, and other providers. Firebase also offers cloud storage for images and files, push notifications to reach users, crash reporting to find bugs, and performance tracking to see how your app runs.
All these services work together smoothly. You can pick only what you need, making it flexible for any project size from small hobby apps to large business applications.
SurrealDB is a database that handles multiple types of data storage without needing different database systems. Think of it as one tool that can work like a traditional database with rows and columns, a document store like MongoDB, and a graph database for connected data—all at the same time.
It is built with Rust programming language, which makes it fast and reliable. You can use it directly from web browsers, mobile apps, or servers. The database includes built-in security features, so you can control who sees what data without writing extra code.
SurrealDB supports real-time updates, meaning your application sees changes instantly without constantly checking for updates. This makes it perfect for chat apps, live dashboards, and similar tools.
