how many user can registration on per bubble project? is same like list of things? only 10.000 user?
No particular limit AFAIK.
The 10,000 limit on a list, is not the number of “thing” in a table, it is the number of things in a list of things.
So you could potentially have 25,000 users, but if you had a list of “friends” on the user, there would be a limit if 10,000 on THAT list.
