Yes, but it’s not something like Firebase that’s gonna allow you to quickly manipulate data entries (like say editing a profile), its better for storing and accessing collections of data that app code or software automation tools tie together into meaningful information. Airtable is better at storing common user content like posts, and Firebase has the security rules necessary to make it useful for storing user profile data. For example, user data can be stored in firebase, organized by a path related like “Users Database>UserID>content”, and have airtable host user posts. Make sure each record in airtable is organized by an automumbered ID, put links of those to your firebase under a Content>Post IDs path (sepatated in commas, e.g. “2, 1”). Then finally, make each airtable record have a field for “UserID” and you’ll be able to link posts back to who actually posted it.
