A segment defines a reusable set of users. You can define a segment based on common user attributes such as location, client device, browser, client application version, or simply using user IDs.
Segments are ideal for targeting a commonly identified set of users across features or dynamic configs. For example, you may create a segment of users that represent your team members or company employees to test a new feature with your colleagues before launching to external users. You may also create different segments of users for English and Spanish speaking countries to deliver a dynamically configured, localized application experience to each geographically identified segment of users.
To get started, see the Statsig guide to create your first segment.
To learn about all that you can do with segments, see the Statsig tutorial on working with segments.
