Facebook’s mobile apps are built for specific operating systems. No longer solely dependent on the Web, Facebook has finer control over mobile app development specific to your iPhone or Android. But by switching to native development two years ago, the company could no longer run A/B tests. So developers built Airlock.

Facebook just released new details about Airlock, the testing framework that allows its developers to compare data from various app implementations and decide which version of the application works best.

The narrative describes challenges many developers face when it comes to fixing the inner workings of applications to best perform for customers. But by going under the hood with its own A/B testing platform, Facebook shows its users how, exactly, it builds a UI people Like.

“We’re one of the biggest app developers and encountering new challenges,” a spokesperson for Facebook told us. “So we’re sharing our experiences so that when other companies hit these challenges they can learn from our process and understand how we did it.”

Even Facebook Makes Mistakes
