Experimentation
Fuel product decisions with real-time data
LaunchDarkly removes silos and complexity from the experimentation process, allowing any team to easily set up and run valid experiments and make improvements based on outcomes.
TARGET AND PERSONALIZE
Context-aware targeting gives you
total control of your releases.
Context-based targeting
Targeting isn’t just about users. LaunchDarkly’s context-based model allows you to create targeting rules that are as simple or as complex as the needs of your application require. Target users, devices, environments, company, location or just about anything else.
Targeting segments
Segments make it easier to group similar targets into a cohort and create feature flag rules for it. You can even import large user segments from product analytics software providers—and sync changes to those segments between your provider and LaunchDarkly.
Progressive rollouts
LaunchDarkly provides the tools to release features gradually and help you gather insights that ensure a feature’s success. Progressively make a feature available to an increasing number of users over time via percentage-based rollouts or expanding segments.
Prerequisites
Prerequisites create feature flag hierarchies that can simplify targeting. Create rules that target each child individually or target a whole subset of child flags via their parent. Prerequisites also help prevent potential errors when two flags are dependent on each other.
Flag organization and management
Effortlessly find, contextualize, and arrange
all your feature flags across your entire organization.
Compare and copy
Compare feature flag configuration settings, including targets and variations, between flags set up in two different environments. For example, compare and clone rules from a staging environment into a production environment, without potentially costly manual errors.
Live Events
Live Events shows you a real-time stream of events arriving in LaunchDarkly from your app. Quickly verify that your flags are set up correctly. Live Events will help you collect more data and decide what to do next or even identify flags that are no longer in use.
Audit logs
The audit log in LaunchDarkly keeps a record of every change made to every flag in your codebase, making it easier to maintain regulatory compliance and retain critical contextual information.
Flag defaults
Create flag configurations that embody best practice and then reuse those flag defaults across multiple projects. Speed up flag creation, remove uncertainty, and reduce risk.
