# Licensed feature availability
As of GitLab 9.4, we've been supporting a simplified version of licensed
feature availability checks via `ee/app/models/license.rb`, both for
on-premise or GitLab.com plans and features.
## Restricting features scoped by namespaces or projects
GitLab.com plans are persisted on user groups and namespaces, therefore, if you're adding a
feature such as [Related issues](../user/project/issues/related_issues.md) or
[Service Desk](../user/project/service_desk.md),
it should be restricted on namespace scope.
1. Add the feature symbol on `STARTER_FEATURES`, `PREMIUM_FEATURES`, or `ULTIMATE_FEATURES` constants in
`ee/app/models/gitlab_subscriptions/features.rb`.
1. Check using:
```ruby
project.feature_available?(:feature_symbol)
```
## Restricting global features (instance)
However, for features such as [Geo](../administration/geo/index.md) and
[Database Load Balancing](../administration/postgresql/database_load_balancing.md), which cannot be restricted
to only a subset of projects or namespaces, the check is made directly in
the instance license.
1. Add the feature symbol to `STARTER_FEATURES`, `PREMIUM_FEATURES` or `ULTIMATE_FEATURES` constants in
`ee/app/models/gitlab_subscriptions/features.rb`.
1. Add the same feature symbol to `GLOBAL_FEATURES`.
1. Check using:
```ruby
License.feature_available?(:feature_symbol)
```
## Restricting frontend features
To restrict frontend features based on the license, use `push_licensed_feature`.
The frontend can then access this via `this.glFeatures`:
```ruby
before_action do
push_licensed_feature(:feature_symbol)
# or by project/namespace
push_licensed_feature(:feature_symbol, project)
end
```
