Why LaunchDarkly.
Scale is hard. AI makes it harder. We’re built for both.
Basic flags work early. At scale, they lack the features, reliability, and guardrails that teams need to move faster and stay safer. At AI speed, it’s chaos. That’s when you need LaunchDarkly.

Target
Take control in production.
Own what ships, when, and to whom in real time—including dynamic and AI-driven behavior.
Target rollouts by user, team, or cohort.
Serve the right features to the right users at the right time, based on any attribute you define.
Make changes without redeploying.
Flip features on or off instantly with sub-200ms propagation across all environments.
Control behavior in any stack or environment.
Integrate flags directly into backend, frontend, mobile, or edge services using 25+ native SDKs.
Control rollout and limit risk.
Use progressive rollouts to validate changes, simulate impact before launch, and instantly shut down features with kill switches if something breaks.
Test and validate in production.
Simulate flag states, preview targeting rules, and confidently test changes before scaling to all users.
Integrate into your workflow.
Work where you code with MCP, Git, CLI, API, or UI—and connect to CI/CD pipelines and 80+ integrations to automate and standardize releases.
De-risk
Ship confidently. Recover instantly.
De-risk every release and recover instantly when needed—even as systems and behavior change in real time.
Scale
Ship faster, no matter how big you grow.
Make teams feel safer and more self-sufficient so they can move faster—while maintaining control across systems.
Scale and standardize releases.
Launch quickly, expand confidently, and standardize rollouts across teams with templates, pipelines, and reusable patterns.
Keep systems clean and maintainable.
Track flag usage, set TTLs, and automatically clean up stale flags to help reduce tech debt over time.
Govern and operate with confidence.
Use RBAC, approvals, and audit logs to control access—and deploy in any environment, including behind your firewall.
