What is LaunchDarkly
LaunchDarkly lets engineering teams manage feature flags, run experiments, and control software releases in real time. It supports progressive rollouts and instant rollbacks without redeploying code. Teams use it to reduce deployment risk and ship updates faster.
Overview
LaunchDarkly provides a platform for managing feature flags across production environments. Developers wrap new functionality in flags and toggle them on or off for specific user segments without changing code. The platform includes SDKs for over 35 languages and frameworks, making integration straightforward across most stacks. Built-in experimentation capabilities let teams measure the impact of changes using statistical analysis. Real-time monitoring and alerting help catch performance issues early during rollouts. AI configuration controls allow teams to manage model parameters and routing logic alongside traditional feature releases.
How to use LaunchDarkly
Teams integrate the SDK into their application, create feature flags in the dashboard, and define targeting rules based on user attributes or percentages. They can then roll features out gradually, monitor performance metrics, and roll back instantly if issues arise. Experiments run on top of flags to compare variants and validate changes with real user data.
