I’m considering developing a mobile app where I want to store user data, content, images, files, and other data sets. Unfortunately, I read that you only offer 500GB for Business, Enterprise & Organizations for €250 a month… 
Can I expand this and get more data storage, or unlimited data storage? Because I’m currently planning a large project with millions of users and downloads, or are there alternative solutions available (such as external storage integration)?
Better to go with Firebase. Adalo is not meant for something like that

@eugen Do you mean programming the entire app entirely with Firebase? Or do you mean connecting the Adalo app to Firebase for the database?
Can use Adalo as frontend and firebase as backend. But Adalo is slow to process even few data, imagine millions of users and GB

@Eugen Thank you for the solution. My last question is, I’m going to upload screenshots and display statistics, and users will only be able to view the screenshots, but all users have to register. So, in this case, would you recommend Firebase?
Personally I’m not sure Firebase is the best choice as a backend for Adalo app.
I’d say Xano first (as there is user integration), maybe Supabase.
@Eugen did you had an experience integrating Firebase with Adalo in production app? Any advantages you see for such solution?

Hi @Victor
I’ve only tried Firebase once for testing (not in a production app), but my impression was that it performed noticeably faster than Xano, especially when handling large amounts of data.
That said, I do see your point , Adalo doesn’t have native integration with Firebase, so getting user authentication and data mapping right can require extra effort compared to Xano, which is plug and play. I guess it really comes down to priorities: if performance and scalability are critical, Firebase can be a strong option, but if ease of integration with Adalo is more important, Xano (or Supabase) probably makes more sense.

@Eugen ok, thanks for the reply.
My biggest concern about FB is that it is a NoSQL database, which means that the whole data management concept is completely different. Adalo can work only with relational databases, and I believe it should be possible to present a FB collection to Adalo as a table, but IMO creating a full-scale setup will be a pain. Moreover creating server-side optimizations will be quite difficult (e.g. in Supabase you can have smth like views, or cascade delete, or triggers, but in Firebase all this kind of stuff should be done with cloud functions probably).
Anyway - thanks for sharing. I wonder if anyone else had an experience integrating FB with Adalo.
Best,
Victor.

Hi @Sabrouch3147 ,
I can’t comment on Firebase usage because I personally haven’t used Adalo that way however thought you might be interested in a recently added Adalo capability (BYOD - Bring Your Own Database). A few weeks ago I created a video demonstrating this feature. Still early days on this but I can confirm it works for basic use cases. 
Happy to answer questions, feel free to email me at jason.gilmore@adalo.com.
