You can now use Custom flags to personalize or experiment with content outside of Contentful, including features, design elements, layouts, or content living in third-party systems.

With Custom flags, you can manage changes without having to replace content entries. Instead of swapping Contentful entries, you can use an ID in your code paired with plain text or JSON to make the change.

NOTE: Custom flags are only available on specific pricing plans. For more information, reach out to your Sales representative.

For more information about working with Custom flags, see the Custom flag change types page and the developer documentation.
