Xojo App iOS, Mac, Windows, Web Sharing data

What is the best way to share data between applications (iOS, Mac, Windows…). When I don’t use Xojo I use Firebase or AWS services.

What do you use in Xojo Development ?

We use a database as the common location, typically with a standard api in front of it so the database isn’t exposed to the internet.

Sorry I don’t understand ¿?

Do you use Xojo Cloud Server?

We do use Xojo Cloud for a few things.

I should clarify that we don’t have one app that does all of these things though. For example, the app that we use for showing the schedule, event location and session feedback for our Xojo Developer Conference is an iOS app and a web app on a Xojo Cloud server. The web app is both a server for the web version and an api for the iOS version to interface with a PostgreSQL database.

Another example would be our Feedback desktop app. It uses a php api to interface with its backend database. Not currently on a Xojo Cloud server, but it will be.
