CADENCE vs LaunchDarkly
LaunchDarkly vs CADENCE: Feature Flags vs Business Impact Testing
LaunchDarkly is the market leader in feature flag management. It helps engineering teams deploy safely with progressive rollouts, kill switches, and flag-based targeting. It is an excellent tool for what it does.
But feature flags and A/B testing solve different problems. Feature flags answer "should we ship this?" — a deployment question. A/B testing answers "does this improve business outcomes?" — a learning question. LaunchDarkly has added experimentation features, but testing remains secondary to its core flag management platform.
CADENCE was built from day one to answer the business impact question. We include feature flags as part of the experimentation workflow, but our focus is on measuring outcomes and communicating results — not managing deployment infrastructure.
Quick Comparison
LaunchDarkly is a feature flag management platform with experimentation add-ons. CADENCE is an A/B testing platform with feature flags included. LaunchDarkly optimizes for safe deployment; CADENCE optimizes for learning and business impact.
Feature Comparison

Where CADENCE Wins
Purpose-built A/B testing. CADENCE was designed for experimentation from the ground up. The visual editor, test calendar, backlog, and Impact View create a complete testing workflow. LaunchDarkly's experimentation is an add-on to a flag management platform, and it shows in the workflow.
Business impact measurement. CADENCE's Impact View shows revenue impact, conversion lift, and executive-ready summaries. LaunchDarkly shows basic experiment metrics but lacks the business-outcome translation layer that makes results actionable for non-technical stakeholders.
Visual testing without code. CADENCE's visual editor lets marketers and product managers create and run tests without engineering involvement. LaunchDarkly's experiments require code changes, which means every test needs an engineering ticket.
Testing workflow. The calendar prevents experiment collisions, the backlog surfaces high-impact ideas with scoring, and templates make common test patterns repeatable. LaunchDarkly has none of these workflow features because its core audience is engineering, not testing programs.
Where LaunchDarkly Might Be Better
Feature flag management at scale. If your primary need is managing hundreds of feature flags across multiple services and platforms, LaunchDarkly is purpose-built for that. CADENCE's feature flags are simpler and designed for experiment-scoped use.
Multi-platform server-side SDKs. LaunchDarkly supports server-side SDKs across dozens of languages and platforms. CADENCE's SDK is client-side JavaScript focused, which covers most web A/B testing but not server-side experimentation across backend services.
The Verdict
If you need A/B testing with business-outcome reporting and a complete testing workflow, choose CADENCE. If you need enterprise-grade feature flag management with experimentation as a secondary capability, choose LaunchDarkly.
