Frequently Asked Questions (FAQs)
-
What is an open source backend platform?
An open source backend platform is a set of tools that help you build the “server side” of your app. “Open source” means the code is public. You can see it, change it, and host it yourself. These platforms usually give you a database, user login (authentication), and file storage. This saves you a lot of time.
-
Why should I use a backend platform instead of building my own?
Building your own backend is hard. You must manage security, databases, user logins, and servers. This takes a lot of time. A backend platform gives you all these things ready to use. You can focus on building the features that make your app special. It helps you launch your app much faster.

Is a free backend platform good for a real application?
Yes, free platforms can be very good. Many of the tools on this list have free tiers that are perfect for new apps. Tools like PocketBase are completely free.
