ConfigCat

Through A/B testing, we can let users guide our decisions, thus removing much of the decision-making strain. As a result of this testing method, we can analyze, test, and refine experimental features on a sample of users without exposing them to everyone. Using ConfigCat’s feature flag services makes the entire A/B testing process easier with the added ability to target specific user segments. With this, we can toggle experimental features on or off quickly from a 10-minute trainable feature flag management interface to switch between states without redeploying our code.
