How GrowthBook compares to LaunchDarkly?
LaunchDarkly customers switch to GrowthBook for trusted experiments, predictable costs, and better control over their stack.
“We don’t need any code changes, we don’t need an app release. We just configure the new tests and launch right away.”
“Our goal was to consolidate everything into a single platform while saving money and ensuring compliance and security.”
“Being able to turn a feature on and off with a flip of a switch is fantastic... That’s so much easier than having to do a deploy or a roll-back.”
“Experimentation showed what customers actually do rather than what we assume they’ll do.”
“People only see the wins, but there’s actually greater value in avoiding losses. We’ve stopped changes that could have cost millions.”
"GrowthBook allowed us to uplevel our code, speed up decision-making, and focus on what we do best—building a world-class AI lending marketplace."
"The fact that we could retain ownership of our data was very, very important. Almost no solutions out there allow you to do that."
“GrowthBook lets us build experiments exactly how we want. The ability to target based on culture and geography, as granular as needed, is a major win for us.”
"The fact that GrowthBook offered us the ability to keep that data in-house was a key reason why we chose to work with them."

FAQs
Follow these links to learn more about how GrowthBook compares to LaunchDarkly for feature flagging and how to migrate from LaunchDarkly.
Moving from LaunchDarkly to GrowthBook is straightforward and most teams are up and running the same day. GrowthBook's dedicated importer pulls in your projects, environments, feature flags, and targeting rules directly from LaunchDarkly via API. After that, swap the LaunchDarkly SDK for the GrowthBook equivalent and you're ready to go.
Yes, both platforms meet standard enterprise security requirements, but GrowthBook alsomeets stricter data residency requirements. GrowthBook supports full self-hosting; your data never leaves your own infrastructure. LaunchDarkly runs on vendor-managed cloud infrastructure with no full self-hosting option.
Yes, GrowthBook works natively with all major data warehouses — Snowflake, BigQuery, Redshift, Postgres, and more. LaunchDarkly's warehouse-native experimentation is currently limited to Snowflake, which requires high-level account permissions to set up.
GrowthBook is much less expensive than LaunchDarkly, especially as your team grows. LaunchDarkly’s design creates vendor lock-in, making it difficult to switch platforms once costs increase. As one reviewer put it, "they can literally charge any amount of money and your alternative is having your own SaaS product break." GrowthBook uses predictable, per-seat pricing without the vendor lock-in.
Companies choose GrowthBook over LaunchDarkly to run more experiments with stronger statistical methods and lower, predictable cost. GrowthBook includes Bayesian and frequentiststatistical engines with sequential testing, CUPED, post-stratification and more advanced statistical methods. LaunchDarkly offers experimentation as a paid add-on with limited testing options.
GrowthBook is built for product experimentation, while LaunchDarkly is built for enterprise release management. GrowthBook helps teams rollout and measure the impact of every feature using their own data warehouse, while LaunchDarkly only controls how and when features ship.
