Wix offers amazing features. But limiting the database blocks the potential. Years ago we were developing a mobile and web app, which we wanted to connect to wix. But not allowing database to fetch and send data to firebase is disappointing.
You can connect WIX to any database that has an open api. It doesn’t have to be the one WIX uses - it can be any database.
