What are Convex and Back4App?
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.
Back4App is a Backend-as-a-Service platform that provides all the backend tools needed for mobile and web applications. You get a database, user authentication system, file storage, APIs, and server-side functions without setting up your own servers.
The platform uses Parse Server, which is open-source technology trusted by many developers. This means you are not locked into proprietary systems. You can choose between NoSQL and PostgreSQL databases depending on your project needs.
Back4App handles the technical infrastructure like hosting, scaling, backups, and security. You connect your frontend application through easy-to-use SDKs for JavaScript, React, Flutter, Android, iOS, and other platforms. The service offers both free and paid plans, making it accessible for projects of any size.
