Protected prompt labels

Langfuse now supports protected prompt labels for better access control over your prompt deployment workflow

Protected prompt labels give project admins and owners the ability to prevent labels from being modified or deleted, ensuring better control over prompt deployment.

Once a label such as production is marked as protected:

viewer and member roles cannot modify or delete the label from prompts, preventing changes to the production prompt version.
admin and owner roles can still modify or delete it, effectively changing the production prompt version

Admins and owners can update a label’s protection status in the project settings.

Availability

Protected labels are available on all Team (Cloud) and Enterprise (Cloud and Self-Hosted) plans. Check your project settings and upgrade if needed to start using this feature.
