Segments

What is a Segment?

A Segment is a re-usable rule that defines a specific subset of your audience. It allows you to group users based on their attributes and share that definition across multiple feature flags.

Instead of recreating the same targeting rules for every feature flag, you can create a Segment once and reference it whenever needed.

In technical terms, a Segment is a collection of conditions that evaluate to true or false for a given context. (See Glossary)

Benefits

• Reusability: Define a rule once and use it in multiple feature flags.
• Consistency: Ensure that audience definitions (e.g., "Beta Users") are identical across all features.
• Efficiency: Apply complex targeting rules quickly without manual repetition.
• Maintainability: Update the Segment definition in one place, and the change automatically applies to all feature flags using it.

Example

Suppose you want to target all internal employees for an internal beta feature. You can create a Segment named Internal Employees.

Rule Definition:

• Context: user
• Attribute: email
• Operator: ends with
• Value: @yourcompany.com

Once this Segment is created, you can simply add the Internal Employees segment to any feature flag rule. This avoids the need to manually check the email domain for every single flag targeting this group.
