What is a Feature Flag? Definition for Product Analytics and Experiments
A feature flag is a switch that controls whether a feature is enabled for users. It lets teams release code separately from feature exposure, target specific cohorts, run experiments, and roll back risky changes quickly.
Feature flags are also called feature toggles, flags, or release toggles.
What feature flags are used for
Feature flags can support:
- Gradual rollouts
- Beta programs
- A/B tests
- Permission-based access
- Regional launches
- Kill switches
- Internal testing
- Plan-based features
- Progressive delivery
Instead of shipping a feature to everyone at once, teams can expose it carefully and measure the impact.
Feature flags and analytics
Analytics is important because feature exposure should be measured. Teams need to know whether the flagged feature improves activation, conversion, engagement, retention, performance, or revenue.
Without analytics, a feature flag only controls rollout. With analytics, it becomes a learning tool.
Feature flag risks
Flags need ownership and cleanup. Old flags can create code complexity. Poor targeting can expose features to the wrong users. Missing measurement can hide bad outcomes.
