How LaunchDarkly feature flags work
LaunchDarkly enables developers to securely manage software features with feature flags on a massive scale. Here’s the quickest way to get started.
Watch: First Feature Flag in < 5 Minutes
Install the right LaunchDarkly SDK for your application code.
Create a feature flag in the LaunchDarkly UI, generating a flag key.
Put software features behind a feature flag with the flag key in your code.
Turn features on/off in LaunchDarkly without needing to redeploy, with changes processed in 200ms worldwide.
How LaunchDarkly experiments work
LaunchDarkly enables anyone—not just data scientists—to run valid product experiments. And it integrates A/B tests with the development workflow. Here’s the quickest way to get started.
Watch: Get Started With Experiments
Wrap every new feature in a feature flag.
Define the performance data you want to collect: conversions, clicks, page load time, etc.
Create a targeted experiment sample or select a random percentage of users tied to a funnel stage.
Record data for assigned metrics and tweak the experiment as needed.
Illustrate data stories with reliable data, giving key stakeholders a shared view of results.
Release the winning feature variation to the full intended audience immediately.
Developer First
Implement LaunchDarkly in just 5 minutes.
With a few lines of code, you can integrate your app and toggle your first feature flag on.
import * as LaunchDarkly from "launchdarkly-js-client-sdk"
const context = {
kind: "user",
key: "context-key-123abc",
name: "anonymous"
};
const client = LaunchDarkly.initialize("<add your client-side key as an env variable>", context);
35+ languages and frameworks

Custom roles and policies
Manage access and permissions across large orgs of diverse teams.
Customizable release dashboard
Organize and filter feature flags by tags or other attributes.
Flag change approvals
Mandate approvals for specific flag changes in accordance with governance standards.
Through our global flag delivery network, which leverages 100+ CDN locations, we ensure the utmost speed and security when evaluating flags—anywhere, anytime.
Private attributes and purpose-built client-side SDKs protect user data. We comply with security standards like SOC II, FedRAMP, HIPAA, and GDPR.
