Dependent Features


Dependent features were first introduced in Unleash 5.7 for Pro and Enterprise users.


Dependent features allow to define a child feature flag that depends on a parent feature flag.
A feature flag can have only one parent dependency but multiple child flags can share the same parent. For a child flag to be activated, its parent dependency must be enabled.

Parent dependency criteria

  • Project Association: Both parent and child flags should belong to the same project.
  • Single Level Dependency: The parent flag can’t have its own parent, ensuring a straightforward, single-level dependency.

Managing dependencies


Introduce dependencies either through the UI or API, also applicable when copying a child feature with an existing parent dependency.

Eliminate them through the UI or API. Dependencies are also removed when archiving a child feature. A parent feature can’t be removed if it would leave a child feature orphaned. To remove both, batch archive them. If Unleash confirms no other child features are using the parent, archiving proceeds.

The Update feature dependency project permission, auto-assigned to admin and project members, allows managing dependencies.

Metrics calculation

Metrics are influenced solely by the evaluation of child features.

Client SDK Support

To make use of dependent feature, you need to use a compatible client. Client SDK with variant support:
