What Are Feature Flags?

Feature flags enable teams to toggle features, roll out updates gradually, and run A/B tests without redeploying code.

In FlagSync, they power Experiments and Metrics by serving variants (e.g., “On” or “Off”) to users.

​
Why Feature Flags Matter

Safe Rollouts

Test features with a subset of users before full release.

Experimentation

Compare variants (e.g., “Buy Now” vs. “Add to Cart”) in A/B/n tests.

Quick Adjustments

Enable or disable features instantly—e.g., during maintenance.

Targeted Rollouts

Roll out to specific groups or percentages, ensuring stability before full deployment.
