What is LaunchDarkly?

Discover how LaunchDarkly can enhance your workflow

LaunchDarkly lets teams ship features safely using flags, targeting and gradual rollouts. Engineers decouple deploy from release, run canary or percentage rollouts and kill features instantly if metrics regress. Experimentation measures impact on key events while governance provides roles, audit trails and approval workflows. SDKs cover major languages and mobile; relay proxies help at scale. Integrations connect CI/CD, observability and incident tools. A free Developer tier serves small projects; paid plans add higher limits, environments and advanced experimentation. Enterprises standardize on LaunchDarkly to reduce incident risk, move faster and prove impact with data.
