Check: https://console.firebase.google.com

You need: JavaScript, Firestore (firebase), Real time database (firebase), Google account

i added firestore but how do i add real time database and javascript?

Similar to Firestore, except you choose Realtime database and create a database, for example, in the United States or in a country near Turkey if you want it to work better for all of Turkey. This allows you to structure a data hierarchy, and to create accounts you use Authentication (you add it like Firestore or RTDB, but select authentication).

ok, later

wow, that's so cool :v

(just like in the roblox)
