Decouple deployments from releases in React

Are you upping your JavaScript game with React? Looking to build more dynamic web applications across multiple platforms? Do you want to use feature flags (feature toggles) to deploy new features to a subset of users, instantly roll back code, and A/B test in production? We've got you. Start feature flagging with LaunchDarkly's React SDK.

Why feature flag management?

LaunchDarkly's feature management platform enables you to use feature flags on a massive scale across a variety of complex use cases. Unlike environment variables, LaunchDarkly flags let you progressively roll out new features to targeted groups of users, disable problematic code paths in 200ms, and take complete control over every feature in your React app.

Introducing feature flag management for React

A best practice in modern software development that reduces risk, accelerates code delivery, and lowers your stress.

Make feature management a reality

Safe continuous delivery

Gain the confidence to ship faster. In separating code deployments from feature releases, LaunchDarkly feature flags allow you to safely test new functionality in production before a formal software launch.

Instant rollbacks

Resolve incidents in real-time. Use feature flags like kill switches to turn off defective code with a single toggle. No engineers scrambling to put out fires, no emergency fixes, no redeploying your entire app.

Progressive rollouts

Use React feature flags to roll out components and features to a specific subset of users. As you gain confidence in a feature's performance, gradually roll it out to the broader userbase.

Collaborative software delivery

Empower business stakeholders to turn features on/off for users. Enhance the customer experience and save engineers time. Developers, deploy when you want. Let the business release later.
