Why migrate from LaunchDarkly to GrowthBook

Companies interviewed that migrated from LaunchDarkly to GrowthBook generally did so not merely to reduce costs, but to combine feature flagging, experimentation, and product analytics in a single platform. Users cited the ability to turn flags into experiments, measure releases with standardized metrics connected to their own data warehouses, and retire multiple homegrown or third-party tools, with Upstart reportedly consolidating three systems. The account argues that AI-driven development increases the need for controlled rollouts, monitoring, rollback capabilities, and agent-accessible workflows, which GrowthBook supports through APIs and MCP integrations for creating, managing, and cleaning up flags. Migration also prompted teams to address accumulated stale flags, improve release practices such as targeting and gradual rollouts, and establish ongoing flag hygiene. Although flag cleanup was described as the largest effort, GrowthBook’s LaunchDarkly Importer, migration scripts, and support were presented as reducing the technical work required to transfer projects, environments, flags, targeting rules, and rollout configurations.
