API Backend

An API backend is the engine room of an application. It holds the database, enforces the rules, and exposes endpoints — an API — that the front-end calls whenever it needs to save a record, fetch a list, or check a permission. When you submit a form and it just works, a backend is doing the work behind it.

Building and running a backend is traditionally the hard part: servers, databases, security, and uptime all have to be handled. It is also the part that a front-end-only tool leaves you to solve.

ybuild generates the API backend along with the interface and runs it as a managed service. You never provision a server or wire up endpoints by hand — the backend ships already hosted on ybuild, powering your app on your own domain.

Do I need to build the API backend myself with ybuild?

No. ybuild generates the API backend — database, endpoints, and rules — and runs it as a managed service, so your app works on your own domain without you setting up or maintaining any servers.
