LaunchDarkly Has a Free Feature Flag Service — Ship Features Safely Without Redeploying

LaunchDarkly Has a Free Feature Flag Service — Ship Features Safely Without Redeploying Deploying code should not equal releasing features. LaunchDarkly decouples deployment from release, letting you control who sees what — without touching your CI/CD pipeline. Feature flags let you wrap new features in toggles. Ship the code, then gradually roll it out to 1%, 10%, 50%, 100% of users. If something breaks, kill the flag instantly — no rollback needed. Why Feature Flags Matter Canary releases — test with 1% of users before full rollout Kill switches — instantly disable broken features A/B testing — show different variants to different user segments Trunk-based development — merge incomplete features behind flags Scheduled launches — flip a flag at midnight, no engineer needed Free Tier (Starter Plan) Up to 1,000 monthly active users Unlimited feature flags Unlimited environments (dev, staging, prod) Server-side and client-side SDKs Flag targeting and segmentation Quick Start: Node.js imp
