This article explains how to use LaunchDarkly feature flags to manage SaaS entitlements across subscription tiers, enabling flexible tenant configurations without maintaining separate code versions.

• LaunchDarkly feature flags enable dynamic entitlement management for Free, Pro, and Business tiers
• Tenant contexts pass subscription tier information to LaunchDarkly for targeting rules
• Tier segments map tenants to their subscription level using context attributes
• Feature flags target tier segments to grant or deny feature access per subscription
• Multivariate flags support rate-limiting features that vary by tier
• Individual tenant exceptions can override baseline entitlements for special cases
• Server-side SDKs evaluate flags using tenant context to control feature access
• Security layers prevent unauthorized access through backend validation and secure mode

LaunchDarkly enables SaaS providers to maintain single-version solutions with configurable entitlements, improving agility and reducing customization overhead.
