# Overview

> Learn the basics of feature flags in FlagSync for flexible feature management.

## 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](/experiments/overview) and [Metrics](/metrics/overview) by serving variants (e.g., "On" or "Off") to users.
