title: Feature Restrictions
---
New self-hosted and [ZITADEL Cloud instances](https://zitadel.com/admin) are unrestricted by default.
Self-hosters can change this default using the DefaultInstance.Restrictions settings section.
Users with the role IAM_OWNER can change the restrictions of their instance using the [Feature Restrictions Admin API](/reference/api/admin).
Currently, the following restrictions are available:
- *Disallow public organization registrations* - If restricted, only users with the role IAM_OWNERS can create new organizations. The endpoint */ui/login/register/org* returns HTTP status 404 on GET requests, and 409 on POST requests.
- *AllowedLanguages* - The following rules apply if languages are restricted:
- Only allowed languages are listed in the OIDC discovery endpoint */.well-known/openid-configuration*.
- Login UI texts are only rendered in allowed languages.
- Notification message texts are only rendered in allowed languages.
- Custom Texts can be created for disallowed languages as long as ZITADEL supports that language. Therefore, all texts can be customized before allowing a language.
Feature restrictions for an instance are intended to be configured by a user that is managed within that instance.
However, if you are self-hosting and need to control your virtual instances usage, [read about the APIs for limits and quotas](/self-hosting/manage/usage_control) that are intended to be used by system users.
