Feature Flags

A technique to enable or disable features at runtime without deploying new code.

What it means

Feature flags (also called feature toggles) let you wrap new features in conditional logic so you can turn them on/off for specific users, segments, or percentages without redeploying code. They enable gradual rollouts, A/B testing, beta programs, and kill switches for problematic features. Tools like LaunchDarkly, Statsig, and PostHog make feature flags easy to implement.

Why it matters

Feature flags reduce deployment risk, enable data-driven product development, and create marketing opportunities. A gradual rollout lets you generate buzz ('Early access to our new feature!'), collect testimonials from beta users, and create content around new launches - all before the full release.

What are feature flags?

Feature flags are a development technique that lets you enable or disable product features at runtime - without deploying new code. They support gradual rollouts, A/B testing, and risk mitigation.

Why should startups use feature flags?

They reduce deployment risk, enable testing with real users, support beta programs, and create marketing moments around gradual feature launches.
