Experiment
on any feature.
Measure the impact of what you ship, with experimentation loved by engineers and product teams.
Eliminate experimentation friction.
Bring experimentation into your release process, using the feature flags you already trust.
Maximize impact, not risk.
Test any feature, model, or prompt. Learn from every release, adapt quickly, and improve over time.
Trust the data.
Replace hunches with statistically sound data. Get reliable insights and ship with confidence.
How it works
Build experiments where your features live; not in a separate tool.
Plan collaboratively in the same tool you use to ship features.
Preview the right audience and preview assignment logic before launch.
Test anything, from page layouts to AI-powered features.
Rest easy while your experiment runs. Gain Insights that drive progress.
Monitor metrics, traffic, and experiment health in real time.
Visualize experiment results and slice by segments for further analysis.
Spot trends early and shift traffic to winning variations with multi-armed bandit experiments.
Make data-informed decisions. Ship winners with one click, or remix your test in real time.
Instantly ship when statistical significance is reached, no redeploys required.
Add more variants and metrics, or adjust targeting as you learn.
Optimize AI-driven features by adjusting logic, inputs, or prompts across iterations, without starting over.
Dive into the why behind each release, then turn insight into your next big win.
Slice results by device, geo, cohort, or any attribute you define.
Visualize results, share with your team, and turn insights into action.
Export everything to your warehouse for custom analysis on business data.
Built for experimentation teams
Engineers
- Leverage feature flags to conduct experiments directly in your workflow.
- Test anything from a simple feature to AI-powered features.
- Ship statistically valid results safely, instantly, without redeploys.
Product Managers
- Visualize experiment results and understand user behavior.
- Slice data by cohort, region, or device to uncover deeper insights.
- Connect feature launches to key business metrics, like conversion and retention.
Data Teams
- Choose the right model—Bayesian or Frequentist—for every test.
- Use trusted statistical models to deliver reliable results and segment data for deeper insights.
- Analyze results using source of truth business data from your warehouse.
Real results from real releases
"LaunchDarkly helped to democratize the experimentation practice and bring together data, product, and engineering teams working together around the same project."
David Tieba
Head of Product Analytics
"LaunchDarkly has given us much more flexibility than our previous tools for feature flagging and A/B testing. We’re able to experiment more effectively and make better data-driven decisions.”

Riley Duncan
Sr. Data Analytst
"By connecting to Snowflake, we can move more quickly when new models are released, which means we can say yes to more ideas. We can take real risks on these things.”
Jon Noronha
Co-founder and Chief Product Officer
"LaunchDarkly helps us safely roll out and experiment with AI and product features without requiring engineering deploys for every variation.”
Vincent L.
Data Scientist, Information Technology and Services Company
"We can test new features with specific users, run A/B tests, and turn off features instantly if something breaks. This means fewer production issues, faster feedback, and more control over our releases.”

Mutual exclusion
Ensure experiments don’t interfere with each other by simply controlling which users see which tests.
Multi-armed bandits
Automatically shift traffic toward winning variations to maximize impact faster.
AI experimentation
Run experiments across prompts, models, and agents to learn what performs best in production.
Data insights made clear.
Slice, segment, and visualize results. Share clear insights that turn learnings into action.

Now that we can join our LaunchDarkly experiments to our Snowflake data, we can measure real user and business outcomes. We can take bigger risks in the kinds of AI features we build, and we can validate that they're worth it because we can see downstream impacts all the way through.
