That depends on two factors:
- the numbers of users to be allowed in your tenant (MindSphere limit). Check the Usage Transperency app for more details. https://<yourtenantname>-usagetransparencyapp.eu2-rc.mindsphere.io/tenant/limits
- the Mendix license you are currently using for your application (Mendix limit). See https://docs.mendix.com/developerportal/deploy/licensing-apps-outside-mxcloud for more information.
The smallest limit is winning.
