Hello! I'm new in Prisma, and i don't know if it is what i need... I have a frontend application with react native but i don't have any data or server yet so i need some way easy to store and request data at first... would prisma solve it?

Yes if you are already familiar with graphql

You need a db with prisma

You can use the demo servers to mess around without managing a db

... and most of the examples come with docker-compose file including a mysql container 🙂

Thanks! This was my other question, can i use the demo database for a production app? Can i use firebase as database? Which one do you recommend?

You should not use demo one in prod, also you can't use firebase too. You can easily launch a heroku system from the Prisma dashboard. More integrations are on the way

Would prisma Cloud replace heroku? Or each one have some specific function?

No no, Prisma cloud is for management of your services. They don't provide hosting yet but makes easy to spin a server in one of the cloud providers
