Global flag delivery architecture

Unrivaled speed, security, and performance.

It starts with your application.

LaunchDarkly’s SDKs embed directly within your application runtime. Whether frontend or backend, container or mobile, our SDKs leverage our flag delivery architecture to control feature releases consistently from anywhere around the world.

Release or roll back any feature in 200ms

Our streaming architecture uses server-sent events (SSE) to deliver feature flag updates to all servers and clients in an environment within 200ms.

Ready to release a new feature?

Turn on the feature flag and enable all clients to receive the change within 200ms.

Is a feature degrading system performance?

Disable the feature in near-real-time—compared to minutes or hours with alternatives—without rolling back your entire deployment.

Need to ship an urgent update on your biggest day of the year?

Ship it to every user instantly!

100+ global points of presence

Our flag delivery network combines a third-party CDN with LaunchDarkly’s distributed core architecture components to enable fast responses and consistent experiences.

• Initialize within an application in 25ms
• Release changes within 200ms
• Deliver toplight experiences to every user, no matter where they are

Multi-region resilience

LaunchDarkly’s architecture provides several layers of resilience across the platform to ensure your systems and clients stay operational at all times, even in the unlikely event of an issue with the LaunchDarkly service. Our self-healing SDKs retrieve and cache flag values and targeting rules in memory. Your applications are always able to resolve flag values and evaluate rules, no matter the circumstances.
