Fast and reliable feature management for the modern enterprise.
LaunchDarkly enables development and operations teams to deploy code at any time, even if a feature isn't ready to be released to users. Wrapping code with feature flags gives you the safety to test new features and infrastructure in your production environments, without impacting the wrong end users.
When you are ready to release more widely, simply update the flag status and the changes are made instantaneously by our real-time streaming architecture.

See What You Can Do with LaunchDarklyFeature flagging is a straightforward concept that can become difficult to manage as your use case scales.
