Best Backend Hosting Platforms for Mobile & Web Apps

When you build a mobile app in React Native or Flutter, you need a backend database and API to support user data. You effectively have two choices: BaaS or PaaS.

BaaS: Backend as a Service

Platforms like Firebase, Supabase, and Appwrite provide ready-made backend infrastructures. You get authentication, databases, and storage right out of the box.

The Catch: Vendor lock-in. You write code specific to their SDKs. Also, executing custom, long-running business logic can be difficult or expensive on entirely serverless BaaS ecosystems.

PaaS: Custom Backend API

If you prefer full control, you write an Express.js, Django, or Spring Boot API yourself, and pair it with a hosted Postgres or Mongo database.

The Solution: You deploy this custom API to a PaaS like Remoud. Remoud manages the server, Docker container, routing, and SSL, while you maintain 100% control over your backend codebase without vendor-specific SDK limits.

Which Is Right For You?

If you need prototyping speed above all else, Supabase or Firebase might win. But if you have specific complex backend logic or demand the freedom to migrate in the future, writing your own Node.js or Python API and deploying on Remoud is the safer long-term choice.
