Enterprise feature management platform with advanced targeting, experimentation, and real-time flag evaluation for controlled rollouts.
LaunchDarkly is the most mature and widely adopted feature management platform, trusted by engineering teams at companies of all sizes to control feature releases with precision. The platform enables developers to wrap new features in feature flags, then gradually roll them out to specific user segments, monitor performance, and instantly roll back if issues arise.
Beyond simple on/off toggles, LaunchDarkly supports percentage rollouts, multivariate flags, and complex targeting rules based on user attributes, segments, and custom rules. The platform's experimentation capabilities allow teams to run A/B tests on features and measure their impact on key metrics before committing to a full rollout.
LaunchDarkly also offers robust governance features including audit logs, approval workflows, and flag lifecycle management to help organizations manage feature flags at scale. With SDKs for every major language and framework, the platform integrates seamlessly into any tech stack and evaluates flags in milliseconds with no performance impact.
