LaunchDarkly

Fast and reliable feature management for the modern enterprise

What is LaunchDarkly?

LaunchDarkly serves a suite of tools that help you ship your code safer, faster, and more effectively with whatever language and frameworks you use today.

How can LaunchDarkly help you?

  • Feature flags let you reduce the risk of releasing new features by rolling them out progressively across subsets of your users over time.
  • Guarded releases monitor the performance of flag releases and configure LaunchDarkly to take action on the results.
  • AI Configs help you customize, test, and roll out new large language models (LLMs) within your generative AI applications.
  • Experimentation lets you validate the impact of features you roll out to your app or infrastructure. You can measure things like page views, clicks, load time, infrastructure costs, and more.
