A simultaneous connection is equivalent to one mobile device, browser tab, or server app connected to the database. Realm imposes hard limits on the number of simultaneous connections to your app's database. These limits are in place to protect both Realm and our users from abuse.


The Standard plan limit is 10,000 and cannot be raised. The Standard plan has a limit of 10,000 simultaneous connections per account.



This limit isn't the same as the total number of users of your app because your users don't all connect at once. If you need more than 10,000 simultaneous connections, please contact us at [email protected]
