You can also manually hibernate branches that won't be used for extended periods. Learn more about the [benefits of scale to zero](/core-concepts/scale-to-zero). ## Project-Level Settings Configure scale to zero defaults for all branches in your project. These settings apply to both base branches and child branches, providing a foundation for cost optimization across your entire project. Project-level compute settings showing scale to zero configuration options Set up automatic hibernation for inactive branches across the project. * **Enable for base branch**: Enable scale to zero for the base branch in the project * **Enable for child branches**: Enable scale to zero for all child branches in the project * **Inactivity period**: Define the duration of inactivity before hibernating the branch (base or child) ## Branch-Level Settings Override project defaults with branch-specific compute settings. Each branch can have its own scale-to-zero configuration or be manually hibernated for extended periods. Branch-level compute settings showing scale to zero and manual hibernation options Customize compute settings for individual branches. * **Scale to zero**: Enable or disable scale to zero for this branch * **Inactivity period**: Define the duration of inactivity before hibernating the branch * **Hibernate branch**: Instead of enabling scale to zero, manually hibernate the branch
