At Unstoppable Domains, we used an in-house feature flag solution for several years. After some research and testing, we decided to migrate to Launch Darkly, a popular feature flagging service. In this post, we’ll discuss why we made the switch and how we’ve benefited from using Launch Darkly. ChallengeOur in-house solution for managing feature flags was very simple: a database table with two main columns, flag_name and is_enabled. The transition was smooth - we migrated a batch of feature flags every week and completed the full transition of 50 flags within a quarter.
