What is a feature gate?

A feature gate is a mechanism for teams to configure what system behavior is visible to users without changing application code. Feature gates are also commonly called feature flags or feature toggles.

When to use feature gates

Feature gates are commonly used as on/off switches to turn a certain system behavior on or off in production. Teams often use feature gates to turn on certain features or behavior for a small percentage of the total user base. Teams may do this to gradually ramp up a software release across their user base to limit the impact of any unanticipated system behavior, or to enable a restricted behavior only for a specific set of users.

To get started, see the Statsig guides to:

• Build your first feature gate
• Analyze your first A/B test
• Log events to create custom metrics
• Use environments
